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

             Summary: Provide option to eagerly copy the new index files in CopyOnRead
                 Key: OAK-3069
                 URL: https://issues.apache.org/jira/browse/OAK-3069
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: lucene
            Reporter: Chetan Mehrotra
            Assignee: Chetan Mehrotra
             Fix For: 1.2.3, 1.3.3, 1.0.17


Currently the CopyOnRead feature lazily starts copying the index files upon first access.
This at times does not work efficiently because the index gets updated frequently and hence
by the time copy is done index would have moved on. Due to this most of the index read turn
out to be remote reads and cause slowness

We should provide an option on per index basis to enable copying the files eagerly before
exposing the new index to the query engine such that any read done is done locally
