Tune a Couchbase Datasource

The Couchbase V1 connector uses the Cross-Datacenter Replication (XDCR) feature of Couchbase to retrieve data stored in Couchbase continuously in real-time.

Because the Couchbase connector retrieves data continuously, two properties are available to control the frequency of commits to Solr, which makes the documents available for user queries. The properties define the maximum number of documents to queue for a commit (set to 50,000 by default) and the maximum amount of time to wait between commits (set to 120 seconds, or 2 minutes). Documents will be committed when one of those thresholds is reached first, meaning that if 2 minutes have passed and there are only 20,000 documents, a commit will occur. Similarly, if only 1 minute has passed and there are 50,000 documents in the queue, a commit will occur. These properties can be adjusted for your own requirements if needed.
