[jira] [Created] (ARROW-6863) [Java] Provide parallel searcher

Liya Fan created ARROW-6863:
-------------------------------

             Summary: [Java] Provide parallel searcher
                 Key: ARROW-6863
                 URL: https://issues.apache.org/jira/browse/ARROW-6863
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Java
            Reporter: Liya Fan
            Assignee: Liya Fan


For scenarios where the vector is large and the a low response time is required, we need to search the vector in parallel to improve the responsiveness.

This issue tries to provide a parallel searcher for the equality semantics (the support for ordering semantics is not ready yet, as we need a way to distribute the comparator).

The implementation is based on multi-threading.
