[jira] [Created] (OAK-760) MongoBlobStore: read from a secondary member when possible

Thomas Mueller created OAK-760:
----------------------------------

             Summary: MongoBlobStore: read from a secondary member when possible
                 Key: OAK-760
                 URL: https://issues.apache.org/jira/browse/OAK-760
             Project: Jackrabbit Oak
          Issue Type: Improvement
            Reporter: Thomas Mueller


Currently, the MongoBlobStore always read from the primary in a replica set.

To improve read performance, reads should be distributed to all members in a replica set.

One possible solution is: first try to read the data on any member. If not found, force reading from the primary.

This is related to OAK-759, but not for the MongoMK (nodes) but for the MongoBlobStore (data store).
