-----------------------------------
Summary: Fix perf regression due to PHOENIX-29
Key: PHOENIX-76
URL: https://issues.apache.org/jira/browse/PHOENIX-76
Project: Phoenix
Issue Type: Bug
Affects Versions: 3.0.0
Reporter: James Taylor
Assignee: Anoop Sam John
Fix For: 3.0.0
Many queries got slower as a result of PHOENIX-29. There are a few simple
checks we can do to prevent the adding of the new filter:
- if the query is an aggregate query, as we don't return KVs in this case, so
we're only doing extra processing that we don't need. For this, you can check
statement.isAggregate().
- if there are multiple column families referenced in the where clause, as the
seek that gets done is better in this case because we'd potentially be seeking
over an entire stores worth of data into a different store.
