-------------------------------------
Summary: Filter regions to scan for local indexes based on data
table leading pk filter conditions
Key: PHOENIX-3941
URL: https://issues.apache.org/jira/browse/PHOENIX-3941
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
Had a good offline conversation with [~ndimiduk] at PhoenixCon about local
indexes. Depending on the query, we can often times prune the regions we need
to scan over based on the where conditions against the data table pk. For
example, with a multi-tenant table, we only need to scan the regions that are
prefixed by the tenant ID.
We can easily get this information from the compilation of the query against
the data table (which we always do), through the
statementContext.getScanRanges() structure. We'd just want to keep a pointer to
the data table QueryPlan from the local index QueryPlan.
