Summary: Improve drop local index performace
Key: PHOENIX-3566
URL: https://issues.apache.org/jira/browse/PHOENIX-3566
Project: Phoenix
Issue Type: Improvement
Reporter: Rajeshbabu Chintaguntla
Assignee: Rajeshbabu Chintaguntla
Fix For: 4.10.0
When we drop local index we need to scan whole data table and in the
coprocessor prepare index deletes and write back to the same table which adds
lot of overhead to the system. We can improve the performance by just dropping
meta data so during compaction we can check we can just write the existing
indexes data back.
