-------------------------------------------------
Summary: Support Index on a generated column that extracts a
scalar value from the JSON column
Key: PHOENIX-7044
URL: https://issues.apache.org/jira/browse/PHOENIX-7044
Project: Phoenix
Issue Type: Sub-task
Components: phoenix
Reporter: Ranganath Govardhanagiri
Assignee: Ranganath Govardhanagiri
As per the Design doc attached we can implement the below proposal:
Using index expressions: Phoenix lets index’s PK to be defined as certain
expressions. Aggregate (sum()), stateless(a constant value) or
non-deterministic(rand()) is not allowed. But expressions like (mycol/2) is
allowed. The Json function could be used as expression with some code changes.
