<p>The LogService is a system which manages a collection of logs. Each
of these logs has a defined state which allows certain operations on that
log or corresponds to actions that the system is taking on that log.</p>
+
<h3 id="open">OPEN</h3>
+
<p>This is the first state for a Log which is created in the LogService. A
Log which is OPEN can be read from or written to. This Log has a corresponding
Raft Group (a quorum of servers) who are participating in the hosting of this
Log.</p>
+
<p>The only transition out from this state is to the CLOSED state.</p>
+
<h3 id="closed">CLOSED</h3>
+
<p>The CLOSED state indicates that a Log is no longer accepting writes. The
Log is still available to be read from the Raft Group.</p>
+
<p>A log can be transitioned from OPEN to CLOSED via the client API, but it
can also be done automatically by the LogService. When a node which was
participating in the Raft Group for this Log becomes unreachable, we consider
this Group to be unhealthy and proactively close it to prevent any additional
writes which may block due to too few nodes to accept a write.</p>
+
<p>The transition from OPEN to CLOSED is one-way: a Log cannot transition back
to the OPEN state from the CLOSED state. A CLOSED log may be deleted from the
system.</p>
+
<p>From the CLOSED state, a log can be transitioned to the ARCHIVING state or the DELETED
state.</p>
+
<h3 id="deleted">DELETED</h3>
+
<p>This is a simple state that is short lived. It tracks the clean up
of any state from the hosting this Log. There are no transitions out
of this state.</p>
+
<h3 id="archiving">ARCHIVING</h3>
+
<p>The ARCHIVING state is reached by the archive API call from
the LogService client. An archival of a log is equivalent to an export
of that log from the beginning of the log file to a known location. See
below for a tangent on exporting versus archiving.</p>
+
<p>This state indicates that the LogService is in the process of copying all
records in the Log from the starting offset of the archival request to the
specified location (a user-provided location or a preconfigured location).
We expect the location to be in some remote storage system such as HDFS or S3.</p>
+
<p>The only transition out from this state is to ARCHIVED.</p>
+
<h3 id="archived">ARCHIVED</h3>
+
<p>A Log can only reach the ARCHIVED state from the ARCHIVING state. This state
is automatically transitioned into when the archival of a log is done in
its entirety.</p>
+
<p>The action of archiving a log is an asynchronous process, managed by the leader
of the Raft Group, thus watching for this state on a log indicates when the
asynchronous archival is complete and the log can be safely read from the
archived location.</p>
+
<p>The only transition out from this state is to DELETED.</p>
+
<h2 id="archive-and-export">Archive and Export</h2>
+
<p>The archive and export API calls are very similar in nature but have
important distinctions in their implementation. As mentioned above,
an archival of a log is an export of the entire log to a specific location.</p>
+
<p>An archival of a log is specification of export in that:</p>
+
<ul>
<li>An archival of a log requires it to be CLOSED.</li>
<li>An archived log cannot receive new writes.</li>
</ul>
+
<p>An export of a log is more generic in that:</p>
+
<ul>
<li>A log does not need to be CLOSED to be exported.</li>
<li>A log can be repeatedly exported (e.g. to multiple locations).</li>
<li>More data can be appended to a log that was exported (but new data would not be reflected in the exported version of the log).</li>
</ul>

<p>The Ratis LogService is an distributed, log implementation built on top of Apache
Ratis. The LogService is a “recipe” on top of Apache Ratis, providing a higher-level
API as compared to Ratis itself. The LogService provides the ability to create named,
durable, append-only data structures with the ability to perform linear reads.</p>
+
<p>Like Ratis, the LogService is designed to be embedded into another application as
a library, as opposed to a standalone daemon. On a confusing note, there are Java
daemons provided for the LogService, but these are solely to be used for testing.</p>

+
<p>This document aims to describe what the intended security deployment model of the Ratis LogService.</p>
+
<p>We will use integration into Apache HBase as an exemplar.</p>
+
<h2 id="background">Background</h2>
+
<p>TLS is technology capable of giving us “strong authentication” over network communication. One-way TLS can provide
encrypted communication while two-way or “mutual” TLS can provide encrypted communication and authentication.</p>
+
<p>One feature of Ratis is that it is decoupled from the RPC transport in use. gRPC is the foremost transport, and
can be configured to use one-way or two-way/mutual TLS. gRPC is the only transport for Ratis which
supports TLS today.</p>
+
<p>However, the majority of components under the “Hadoop Umbrella” rely on Kerberos to guarantee strong authentication.
In this respect, use of TLS is jarring. However, gRPC does not support SPNEGO (which allows Kerberos authentication)
which all but requires the use of two authentication mechanisms when combining Ratis with other projects (like HBase).</p>
+
<p>We anticipate the use of the Ratis LogService as an “embedded WAL” inside of HBase RegionServers and Masters
will result in HBase services using Kerberos authentication to talk to HDFS as well as TLS for Ratis-internal
communication (intra-server Ratis communication and client-server Ratis communication).</p>
+
<h2 id="mutual-tls">Mutual TLS</h2>
+
<p>Mutual TLS relies on a common certificate authority (CA) to issue all certificates which forms a circle
of trust. Certificates generated by the same CA can be used to set up a mutual TLS connection. A certificate
generated by one CA cannot be used to set up a mutal TLS connection to a service using a certificate
generated by a different CA outside of the circle of trust. [1]</p>
+
<p>To control the clients and servers with one instance of the LogService, we want to use a single CA to generate
certificates for clients and servers. We will consider this as an invariant going forward.</p>
+
<h2 id="hbase-examplar">HBase Examplar</h2>
+
<p>We expect the following material to be provided for every HBase service using Ratis:</p>
+
<ul>
<li>File containing an X.509 certificate in PEM format</li>
<li>File containing the PKCS private key in PEM format</li>
<li>File containing the X.509 certificate for the CA</li>
</ul>
+
<p>OpenSSL is capable of creating each of these; however, for this document, we will assume
that you already have these pre-made. The server certificate and private key are unique to every
host participating in the HBase cluster. The server certificate and truststore are not sensitive,
but the private key is sensitive and should be protected like a password.</p>
+
<p>Every component in HBase using the Ratis LogService would need to ensure that each LogService StateMachine is
configured to use the server keystore and truststore. The LogService state machines would need to constructed
with the appropriate configuration options to specify this TLS material:</p>

this TLS material via the HBase configuration (hbase-site.xml), passing it down into the WALProvider
implementation. As the WALProvider is the broker that doles out readers and writers, and would also, presumably
manage the creation of the StateMachines, it can set up the proper Ratis configuration from the HBase configuration.</p>

<p>The Ratis LogService is an distributed, log implementation built on top of Apache
Ratis. The LogService is a “recipe” on top of Apache Ratis, providing a higher-level
API as compared to Ratis itself. The LogService provides the ability to create named,
durable, append-only data structures with the ability to perform linear reads.</p>

<p>Like Ratis, the LogService is designed to be embedded into another application as
a library, as opposed to a standalone daemon. On a confusing note, there are Java

<p>The LogService is a system which manages a collection of logs. Each
of these logs has a defined state which allows certain operations on that
log or corresponds to actions that the system is taking on that log.</p>
+
<h3 id="open">OPEN</h3>
+
<p>This is the first state for a Log which is created in the LogService. A
Log which is OPEN can be read from or written to. This Log has a corresponding
Raft Group (a quorum of servers) who are participating in the hosting of this
Log.</p>
+
<p>The only transition out from this state is to the CLOSED state.</p>
+
<h3 id="closed">CLOSED</h3>
+
<p>The CLOSED state indicates that a Log is no longer accepting writes. The
Log is still available to be read from the Raft Group.</p>
+
<p>A log can be transitioned from OPEN to CLOSED via the client API, but it
can also be done automatically by the LogService. When a node which was
participating in the Raft Group for this Log becomes unreachable, we consider
this Group to be unhealthy and proactively close it to prevent any additional
writes which may block due to too few nodes to accept a write.</p>
+
<p>The transition from OPEN to CLOSED is one-way: a Log cannot transition back
to the OPEN state from the CLOSED state. A CLOSED log may be deleted from the
system.</p>
+
<p>From the CLOSED state, a log can be transitioned to the ARCHIVING state or the DELETED
state.</p>
+
<h3 id="deleted">DELETED</h3>
+
<p>This is a simple state that is short lived. It tracks the clean up
of any state from the hosting this Log. There are no transitions out
of this state.</p>
+
<h3 id="archiving">ARCHIVING</h3>
+
<p>The ARCHIVING state is reached by the archive API call from
the LogService client. An archival of a log is equivalent to an export
of that log from the beginning of the log file to a known location. See
below for a tangent on exporting versus archiving.</p>
+
<p>This state indicates that the LogService is in the process of copying all
records in the Log from the starting offset of the archival request to the
specified location (a user-provided location or a preconfigured location).
We expect the location to be in some remote storage system such as HDFS or S3.</p>
+
<p>The only transition out from this state is to ARCHIVED.</p>
+
<h3 id="archived">ARCHIVED</h3>
+
<p>A Log can only reach the ARCHIVED state from the ARCHIVING state. This state
is automatically transitioned into when the archival of a log is done in
its entirety.</p>
+
<p>The action of archiving a log is an asynchronous process, managed by the leader
of the Raft Group, thus watching for this state on a log indicates when the
asynchronous archival is complete and the log can be safely read from the
archived location.</p>
+
<p>The only transition out from this state is to DELETED.</p>
+
<h2 id="archive-and-export">Archive and Export</h2>
+
<p>The archive and export API calls are very similar in nature but have
important distinctions in their implementation. As mentioned above,
an archival of a log is an export of the entire log to a specific location.</p>
+
<p>An archival of a log is specification of export in that:</p>
+
<ul>
<li>An archival of a log requires it to be CLOSED.</li>
<li>An archived log cannot receive new writes.</li>
</ul>
+
<p>An export of a log is more generic in that:</p>
+
<ul>
<li>A log does not need to be CLOSED to be exported.</li>
<li>A log can be repeatedly exported (e.g. to multiple locations).</li>
<li>More data can be appended to a log that was exported (but new data would not be reflected in the exported version of the log).</li>
</ul>

-<!-- raw HTML omitted -->
-<!-- raw HTML omitted -->
-<p>This document aims to describe what the intended security deployment model of the Ratis LogService.</p>
-<p>We will use integration into Apache HBase as an exemplar.</p>
-<h2 id="background">Background</h2>
-<p>TLS is technology capable of giving us “strong authentication” over network communication. One-way TLS can provide
-encrypted communication while two-way or “mutual” TLS can provide encrypted communication and authentication.</p>
-<p>One feature of Ratis is that it is decoupled from the RPC transport in use. gRPC is the foremost transport, and
-can be configured to use one-way or two-way/mutual TLS. gRPC is the only transport for Ratis which
-supports TLS today.</p>
-<p>However, the majority of components under the “Hadoop Umbrella” rely on Kerberos to guarantee strong authentication.
-In this respect, use of TLS is jarring. However, gRPC does not support SPNEGO (which allows Kerberos authentication)
-which all but requires the use of two authentication mechanisms when combining Ratis with other projects (like HBase).</p>
-<p>We anticipate the use of the Ratis LogService as an “embedded WAL” inside of HBase RegionServers and Masters
-will result in HBase services using Kerberos authentication to talk to HDFS as well as TLS for Ratis-internal
-communication (intra-server Ratis communication and client-server Ratis communication).</p>
-<h2 id="mutual-tls">Mutual TLS</h2>
-<p>Mutual TLS relies on a common certificate authority (CA) to issue all certificates which forms a circle
-of trust. Certificates generated by the same CA can be used to set up a mutual TLS connection. A certificate
-generated by one CA cannot be used to set up a mutal TLS connection to a service using a certificate
-generated by a different CA outside of the circle of trust. [1]</p>
-<p>To control the clients and servers with one instance of the LogService, we want to use a single CA to generate
-certificates for clients and servers. We will consider this as an invariant going forward.</p>
-<h2 id="hbase-examplar">HBase Examplar</h2>
-<p>We expect the following material to be provided for every HBase service using Ratis:</p>
-<ul>
-<li>File containing an X.509 certificate in PEM format</li>
-<li>File containing the PKCS private key in PEM format</li>
-<li>File containing the X.509 certificate for the CA</li>
-</ul>
-<p>OpenSSL is capable of creating each of these; however, for this document, we will assume
-that you already have these pre-made. The server certificate and private key are unique to every
-host participating in the HBase cluster. The server certificate and truststore are not sensitive,
-but the private key is sensitive and should be protected like a password.</p>
-<p>Every component in HBase using the Ratis LogService would need to ensure that each LogService StateMachine is
-configured to use the server keystore and truststore. The LogService state machines would need to constructed
-with the appropriate configuration options to specify this TLS material:</p>
