------------------------------------------------
Summary: Support index merge optimizations
Key: PHOENIX-1801
URL: https://issues.apache.org/jira/browse/PHOENIX-1801
Project: Phoenix
Issue Type: New Feature
Reporter: Rajeshbabu Chintaguntla
Assignee: Rajeshbabu Chintaguntla
Priority: Minor
When we have multiple indexes some times there is chance that we may select an
index with that we may need to scan through huge number of records to find
matching records. But in some cases merging two or more indexes results may
give better result.
Support similiar index merge optimizations as in mysql
https://dev.mysql.com/doc/refman/5.0/en/index-merge-optimization.html
This can be supported with local indexes without much overhead. We have
supported the same feature in hindex(https://github.com/Huawei-Hadoop/hindex/)
which is giving better results as well.
