Andrey Kisilevskiy enabled ScyllaDB compatibility for the Cassandra sink connector in Apache Pulsar, broadening database support for users seeking a drop-in replacement for Cassandra. He contributed both to the apache/pulsar-site repository by adding detailed documentation and to apache/pulsar by implementing integration tests using Java and containerization. His work introduced a ScyllaDB container for automated testing, updated test cases to validate ScyllaDB functionality, and improved CI coverage for these scenarios. This approach ensured early detection of compatibility issues and streamlined validation processes, enhancing reliability for teams integrating ScyllaDB with Pulsar in production environments. No bugs were reported.
