Hi Dhruva,

There are definitely some performance improvements to Storage Engine in
Cassandra 3.10 which make it worth the upgrade. Note that Cassandra 3.11
has further bug fixes and it may be worth considering a migration to that
version.

Regarding the issue of building a Cassandra 3.10 RPM, it sounds like the
team have built their own custom spec file? Has the team looked at using
the project spec file and associated instructions in Apache Cassandra
GitHub mirror?

https://github.com/apache/cassandra/tree/cassandra-3.10/redhat

Kind regards,
Anthony
