Summary: Create secondary primary index
Key: ASTERIXDB-2016
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2016
Project: Apache AsterixDB
Issue Type: Improvement
Components: IDX - Indexes
Reporter: Ali Alsuliman
This change is regarding introducing secondary primary index. The secondary
primary index is a secondary B-Tree that is built on the primary keys of the
dataset but only stores the {PK} instead of the regular case {SK,PK}. The
purpose of this secondary is to optimize queries like SELECT count(*). Instead
of scanning the primary index, the secondary primary index would be used to
answer such queries.
