Summary: CDC DDL to support maxLookback for CDC index
Key: PHOENIX-7671
URL: https://issues.apache.org/jira/browse/PHOENIX-7671
Project: Phoenix
Issue Type: Improvement
Reporter: Viraj Jasani
TTL of the CDC index is same as the maxLookback configured at the cluster
level. If the data table has different value of maxLookback than cluster level,
the table level maxLookback is not used as TTL by the cdc index of the same
data table. Any table property sync from the data table to index table can only
be efficiently done if the table property is stored in SYSTEM.CATALOG.
The maxLookback is not stored in SYSTEM.CATALOG, however it can be stored in
HBase TableDescriptor.
The purpose of this Jira is to provide CDC DDL statement with maxLookback value
that should be used as CDC index maxLookback (and therefore it's TTL) value,
regardless of the maxLookback value configured at the cluster level. This
allows various CDC indexes to have their own TTL values.
