Worked on expanding Apache Pulsar’s database compatibility by enabling ScyllaDB support for the Cassandra sink connector and developing comprehensive integration tests. In the apache/pulsar-site repository, contributed detailed documentation outlining ScyllaDB compatibility, allowing users to adopt ScyllaDB as a drop-in replacement for Cassandra without code changes. Enhanced the apache/pulsar repository by adding integration tests using Java and containerization, introducing a ScyllaDB container and updating test cases to validate seamless interoperability. This work improved continuous integration coverage, enabling early detection of regressions and smoother validation of ScyllaDB scenarios, ultimately supporting broader adoption and reliability for Pulsar deployments with ScyllaDB.
