I am using Java ORC tool (https://orc.apache.org/docs/java-tools.html) to convert JSON records into ORC files. I am querying the ORC files on Amazon Athena. It is working like a charm.
My question: can I use the same Java ORC tool to convert JSON records into a bucketed ORC table?
If not, should I use Apache Hive to perform the conversion from JSON records into a bucketed ORC table?
I want to see if bucketed ORC files increase the performance of my queries on Amazon Athena.
I look forward to hearing from you.
All the best,
