--------------------------------

             Summary: Multi-shard serving
                 Key: BLUR-4
                 URL: https://issues.apache.org/jira/browse/BLUR-4
             Project: Apache Blur
          Issue Type: Improvement
            Reporter: Aaron McCurry


Basically allow the same shard index to be served by more than one shard server.

This will be fairly easy for table read only tables (tables that are only updated via MapReduce),
because the shard server will automatically refresh the index once the MapReduce job commits
the indexes.

Tables that allow for NRT updates via the mutate call in Thrift will need to have some mechanism
built to allow for the follower shard servers to get NRT updates from the leader server.
