Hi
I need some help setting up dynamic multicore replication.
We are changing our setup from a replicated single core index with
multiple document types, as described on the wiki[1], to a dynamic
multicore setup. We need this so that we can display facets with a zero
count that are unique to the document 'type'.
So when indexing new documents we want to create new cores on the fly
using the CoreAdminHandler through SolrJ.
What I can't figure out is how I setup solr.xml and solrconfig.xml so
that a core automatically is also replicated from the master to it's
slaves once it's created.
I have a solr.xml that starts like this:
<?xml version='1.0' encoding='UTF-8'?>
<solr persistent="true">
<cores adminPath="/admin/cores">
</cores>
</solr>
and the replication part of solrconfig.xml
master:
<requestHandler name="/replication" class="solr.ReplicationHandler">
<lst name="master">
<str name="replicateAfter">startup</str>
<str name="replicateAfter">optimize</str>
<str name="confFiles">schema.xml</str>
</lst>
</requestHandler>
slave:
<requestHandler name="/replication" class="solr.ReplicationHandler">
<lst name="slave">
<str name="masterUrl">http://localhost:8081/solr/replication</str>
<str name="pollInterval">00:00:20</str>
</lst>
</requestHandler>
I think I should change the masterUrl in the slave configuration to
something like:
<str
name="masterUrl">http://localhost:8081/solr/${solr.core.name}/replication</str>
So that the replication automatically finds the correct core replication
handler.
But how do I tell the slaves a new core is created, and that is should
start replicating those to?
Thanks in advance.
Thijs
