Summary: Improve performance of Selftune ORC Writer
Key: GOBBLIN-1898
URL: https://issues.apache.org/jira/browse/GOBBLIN-1898
Project: Apache Gobblin
Issue Type: Improvement
Components: gobblin-core
Reporter: William Lo
Assignee: Abhishek Tiwari
The ORCWriter's new self tuning feature leads to slower write frequency when it
comes to ingesting datasets with a low volume of records.
This is primarily caused by the assumption that the native ORC writer will be
saturated, which leads to the memory footprint of STRIPE_SIZE +
avgSizeOfRecord*rowsBetweenMemoryCheck.
However, this is generally not the case when there are only a few records to
write due to a low volume dataset, and causes slow writes. We should utilize a
newer API on ORCWriter brought in by [https://github.com/apache/orc/pull/1057]
