----------------------------------------
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.
