-------------------------------------
Summary: Improve explain plan
Key: PHOENIX-1809
URL: https://issues.apache.org/jira/browse/PHOENIX-1809
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
Two changes:
1) We already output the limit information, so it's redundant to display the
PageFilter filter. Instead we should skip that filter in ExplainTable when we
generate the explain plan - there are about 5 places in the code that need to
be changed that expect this in the explain plan.
2) Instead of the hacky boolean we pass through MergeSortTopNResultIterator to
control the output of the server-side order by/limit, we should output that
information in ExplainTable as well. We'd need to pass through the LIMIT
information there too. Then the MergeSortTopNResultIterator would only output
the CLIENT MERGE SORT step.
