Yonik Seeley commented on SOLR-2355:
------------------------------------
Some sample configuration:
{code}
<updateRequestProcessorChain name="distrib">
<processor class="com.lucid.update.DistributedUpdateProcessorFactory">
<!-- example configuration...
"shards should be in the *same* order for every server
in a cluster. Only "self" should change to represent
what server *this* is.
<str name="self">localhost:8983/solr</str>
<arr name="shards">
<str>localhost:8983/solr</str>
<str>localhost:7574/solr</str>
</arr>
-->
</processor>
<processor class="solr.LogUpdateProcessorFactory">
<int name="maxNumToLog">10</int>
</processor>
<processor class="solr.RunUpdateProcessorFactory"/>
</updateRequestProcessorChain>
{code}
Now on any update command, you can set update.processor=distrib and have
distrib indexing controlled by the "shards" and "self" params, either
configured in solrconfig, or passed in w/ the update command.
Or if you don't want to have to specify update.processor=distrib, you can set
it as the default update processor for any update request handlers:
{code}
<!-- CSV update handler, loaded on demand -->
<requestHandler class="solr.CSVRequestHandler" name="/update/csv"
startup="lazy">
<lst name="defaults">
<str name="update.processor">distrib</str>
</lst>
</requestHandler>
{code}
> simple distrib update processor

> Priority: Minor
> Attachments: DistributedUpdateProcessorFactory.java,
> TestDistributedUpdate.java
>
>
> Here's a simple update processor for distributed indexing that I implemented
> years ago.
> It implements a simple hash(id) MOD nservers and just fails if any servers
> are down.
> Given the recent activity in distributed indexing, I thought this might be at
> least a good source for ideas.
