Rajesh Balamohan commented on HIVE-17745:
-----------------------------------------
Image attached is from correct profiler snapshot. ThreadLocal is from
LazyBinaryUtils->writeVLong. That needs to be fixed as well.
> FileSinkOperator: do not invoke updateProgress for every record

> Depending on the query and the number of records, {{updateProgress}} shows up
> in profiler as hotspot. It would be good to consider updating the progress on
> completing "x" number of records instead of invoking it for every record.
