> 8 CTAS queries were executed sequentially to write TPC-H text data into
> Parquet. After successfully writing a few tables, CTAS failed with OOM.
> Restarting Drillbits fixed the problem and re-run of pending CTAS queries
> completed. This process was done twice in-order to complete all 8 tables to
> be written. Overall source was 30TB in size.
> Queries attached. Query profile for one of the CTAS which failed is attached.
> Logs indicated that the Drillbit was out of Direct Memory.
> Can share more details as required.
