Subject [jira] [Commented] (SOLR-6266) Couchbase plug-in for Solr

Karol Abramczyk commented on SOLR-6266:
---------------------------------------

Joel,

I confirmed today, that Couchbase replicates each document to only one of the running CAPIServers.
My test configuration was Solr 1 and 2 running CAPIServers 1 and 2. Couchbase test bucket
had 2 documents A and B. Only CAPIServer 1 was configured for replication with Couchbase,
but in CouchbaseBehaviour.getNodesServingPool() method it was placing info about itself and
CAPIServer 2 as well. So you were right about the Couchbase replication. But it also seems
that only one CAPIServer configured with Couchbase is sufficient as long as it knows about
the other CAPIServers in this cluster. We could register operating CAPIServers in ZooKeeper,
to have this info available for every node. I didn't check what happens if more CAPIServers
is configured with Couchabse XDCR.

> It would be great if users could connect Couchbase and Solr so that updates to Couchbase
can automatically flow to Solr. Couchbase provides some very nice API's which allow applications
to mimic the behavior of a Couchbase server so that it can receive updates via Couchbase's
normal cross data center replication (XDCR).
> One possible design for this is to create a CouchbaseLoader that extends ContentStreamLoader.
This new loader would embed the couchbase api's that listen for incoming updates from couchbase,
then marshal the couchbase updates into the normal Solr update process. 
> Instead of marshaling couchbase updates into the normal Solr update process, we could
also embed a SolrJ client to relay the request through the http interfaces. This may be necessary
if we have to handle mapping couchbase "buckets" to Solr collections on the Solr side.
