Samarth Jain updated PHOENIX-1927:
----------------------------------
Attachment: PHOENIX-1927.patch
In 4.3.1, we don't have the iterator.peek() call that was made to fix perf
regression seen in https://issues.apache.org/jira/browse/PHOENIX-1899. Also,
calling iterator.peek() in the call() method will negate the effect of delaying
Scanner creation since it will end up creating the scanner itself.
Attaching a patch that does a couple of things:
1) Always delays creation of scanners until requested.
2) Removes the iterator.close() call from ChunkedResultIterator.java.
The perf regression that you saw [~jamestaylor], it is likely we might still
have it. If this patch validates that lease expirations are no longer an issue,
then we can build something slightly more sophisticated/specialized for index
creation or upsert selects.
[~mujtabachohan] - can you please give this patch a try? It is against the
latest of 4.3. Thanks!
