----------------------------------------

             Summary: When data columns get TTLed, we need inline index validation to publish
a metric for this
                 Key: PHOENIX-5841
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5841
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Gokcen Iskender


We do index writes as full row writes. This means all columns keep get re-written to index
and they have a current timestamp.

However, if there is a column that did not get updated for a long time (like Created_By type
of columns that don't change) the regular scan that IndexScrutiny uses doesn't return this
column even though we might see it in the raw scan.

IndexScrutiny mark these rows as invalid because data table had TTL columns and index table
have it.

Index inline validation also marks these as "Index has extra columns" if the column got TTLed.
