[jira] [Created] (OPENJPA-2220) Persistent field fetching statistic
tool
Helen Xu created OPENJPA-2220:
---------------------------------
Summary: Persistent field fetching statistic tool
Key: OPENJPA-2220
URL: https://issues.apache.org/jira/browse/OPENJPA-2220
Project: OpenJPA
Issue Type: Task
Components: performance
Affects Versions: 2.3.0
Reporter: Helen Xu
Assignee: Helen Xu
This task is to create a statistic tool which monitors the persistent fields fetching and finds out the fields which are never accessed. Based on the statistic data, user can set the field access type to LAZY to improve the performance by eliminating the data loading and processing time.

The documentation refers the availability of this feature or OpenJPA Tools repository.
I think this is the first time we are referring to OpenJPA tools from our main documentation pages.
Several useful tools in the past has been floating around. Please open a separate discussion thread on how best we could organize our tools and ensure that they reach the users.

--------------------------------------
After thinking more about this last night I'm thinking we could also exclude fields that are currently marked lazy.... telling the user that they didn't access a field marked as LAZY seems like noise. Thoughts?

We should also exclude version and primary key fields as I could see where those fields aren't used directly by application code, but they are still important to the runtime.

Rick Curtis commented on OPENJPA-2220:
--------------------------------------
I committed revision 1356860 to trunk.
This first iteration of this tool is limited in usage. Currently it is not configurable. Once it is on the classpath, it starts running. When you take it off the classpath, it stops running. It is also depended upon runtime (ie: javaagent or container enhancement) enhancement.
I modified a number of things from the original patch to make it more usable... When the code first gets loaded up you'll see this message[1] so a user is notified when it is running. Also, when the statistics are dumped you'll see a message along these lines[2].
I'll also note that I modified the pom to spit out another jar file that allows this tool to work in a WebSphere environment.

Thanks for your comments.
I'll make the code change to exclude the PK fields. Version fields are excluded.
For the boolean field, the enhancer also generate the getXXXX method. it is covered in the test case.

I am inviting a discussion on tools to get a better focus/attention of other members on such activity. The tools are "unsupported" in some way -- meaning the processes (distribution, documentation, release) around them arr not as matured as that of OpenJPA.

Pinaki Poddar commented on OPENJPA-2220:
----------------------------------------
I think it is a good/useful feature. And I appreciate your contribution.
I would suggest to expand the scope of this idea to collect more statistics on field access patterns. It has been a long-held wish for many original OpenJPA developers to collect such detailed statistics, so that based on the access pattern of correlated fields we can prescribe which fetch groups will best serve an applications need.
A nit: to determine whether a field is persistent, the patch code checks AccessCode and if the bean-method starts with "getX" etc. That check should include boolean fields which may start with "is". You should find the logic somewhere (do not remember exactly where, but around AccessCode or classes that use it), some code that determines whether a named field is persistent.

I thought we came the consensus that if the tool has a dependency on a version of the runtime, it needs to live with the runtime code?. If it has no runtime dependency, it would live in the seperate openjpa-tools repository?
