[jira] [Created] (OAK-11108) Tree store: support parallel indexing

Thomas Mueller created OAK-11108:
------------------------------------

             Summary: Tree store: support parallel indexing
                 Key: OAK-11108
                 URL: https://issues.apache.org/jira/browse/OAK-11108
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: indexing
            Reporter: Thomas Mueller


The tree store (unlike the flat file store) allows relatively easily to index in parallel, that is using multiple threads. 

We already have implemented this by splitting the flat file store, but this requires that we split at the exact "border" of lucene documents. Splitting takes time, is complicated (where is the border exactly?), and doesn't always work eg. if index definitions have conflicting "borders" (eg. indexing folders and indexing assets and pages at the same time).
