Joel Bernstein commented on SOLR-6266:
--------------------------------------
Andrzej, you may be right, but let's confirm. It seems like the right design
for XCDR would be to only replicate each document once across datacenters. Then
let the receiving node handle the intra-cluster replication. I'll try to get
confirmation on which approach is used.

> 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.
