Review request for atlas, David Kantor and Neeru Gupta.


Bugs: ATLAS-1390
    https://issues.apache.org/jira/browse/ATLAS-1390


Repository: atlas


Description
-------

This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.

IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.

IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.


Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage to java dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.

 By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

Still going through the review, will apply the patch and see if the build is fine. Should be good for a commuit if it doesn't interfere with any atlas functionality.

    If it's dependent on Java 8 why not use JDK Function here.
    
    Also consider renaming it AtlasToIBMPropertyConversion or something similar

    Complete parameterization instead of concatenation and parameter hybrid.

> This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.

> 
> Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.
> 
>  By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

    But we should still set the attribute which affects memory usage for compiled query cache.

> This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.

> Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.
> 
>  By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

The executeGremlin call has changed and internally it uses a script engine (the same one) too. So doesn't make sense to pass around the script engine anymore only the bindings.

> This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.

> Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.
> 
>  By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

> This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.

> Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.
> 
>  By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

> This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.

> Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.
> 
>  By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

Bugs: ATLAS-1390
    https://issues.apache.org/jira/browse/ATLAS-1390


Repository: atlas


Description
-------

This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.

IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.

IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.


Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.

 By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

Yes, I added changes to support this.

Neeru fixed this particular issue in the titan1 changes.

> This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.

> Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.

> This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.
> 
> 
> Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.
> 
>  By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

Review request for atlas, David Kantor and Neeru Gupta.


Bugs: ATLAS-1390
    https://issues.apache.org/jira/browse/ATLAS-1390


Repository: atlas


Description (updated)
-------

This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.

IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.

IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.


Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage the java version dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.

 By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.

Review request for atlas, David Kantor and Neeru Gupta.


Changes

removed unused code.


Bugs: ATLAS-1390
    https://issues.apache.org/jira/browse/ATLAS-1390


Repository: atlas


Description
-------

This work item adds IBM Graph as a graph database that can be used by Atlas.  There are some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.  The code here is the result of many months of development effort.  It was contributed to by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private fork of Atlas and is now being added to the public Atlas so that others can benefit from it.

IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan though in that all of the interactions with it requires calling a REST API.  This implementation is optimized to make as few REST API calls as possible by combining the update operations into a single Gremlin script that gets sent when the transaction is committed.  It also has full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect committed changes.

IBM Graph also has some restrictions that a normal Titan instance would not.  Because it is a shared environment, there is a restriction that only queries with an initial indexed predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped when ibm-graph is being used as the graph backend.


Note that this implementation depends on Tinkerpop 3 classes, which require Java 8.  To manage to java dependency, we're following a similar route to what we did for Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still create a jar file which is basically empty.  This is needed so that there is a jar in place to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.  If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project are only run if the ibm-graph profile is enabled though.

 By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention, you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml to configure the IBM Graph service.  This is described in the readme.
