----------------------------------------
Summary: Store table metadata last modified timestamp in PTable /
System.Catalog
Key: PHOENIX-6186
URL: https://issues.apache.org/jira/browse/PHOENIX-6186
Project: Phoenix
Issue Type: New Feature
Reporter: Geoffrey Jacoby
Assignee: Geoffrey Jacoby
Fix For: 4.16.0
There are many reasons why it's useful to know when a particular table's
metadata was last modified. It's helpful when solving cache coherency problems,
and also in order to interact with external schema registries which may have
multiple versions of a particular schema and require a timestamp to resolve
ambiguities.
This JIRA will add a last modified timestamp field to System.Catalog, to be
updated both when creating a table/view and also when adding or removing a
column. Changing purely internal Phoenix properties will not update the
timestamp.
