Purpose
When querying the
$row_trackingsystem table with filters,IllegalArgumentException: Row tracking field name '_ROW_ID' conflicts with existing field namesis thrown. Spark silently catches this exception and falls back to post-scan filtering,
so query results are correct but predicates are not pushed down.
