Viraj Jasani updated PHOENIX-7671:
----------------------------------
Description:
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.
The purpose of this Jira is to sync the value of maxLookback from data table to
index table's TableDescriptor while creating the index. Similarly, when the
maxLookback value of the data table is altered using ALTER TABLE DDL, same
value should be applied to all indexes.
The major compaction of CDC index should therefore consider data table's
maxLookback value (from data table's descriptor) as it's TTL value.
