## Summary This PR adds comprehensive ScyllaDB support to the Flink Cassandra Connector, validating ScyllaDB as a drop-in replacement for Apache Cassandra. All connector features (sources, sinks, batch formats, exactly-once semantics) have been tested against ScyllaDB 2025.1.4 (latest open source version). ## Motivation ScyllaDB is a high-performance, drop-in replacement for Apache Cassandra that maintains full CQL protocol compatibility. ## Implementation Approach Following @echauchot's [guidance](https://github.com/apache/flink-connector-cassandra/pull/32#issuecomment-3452345147) to **"add ITests on ScyllaDB using testContainers"** without modifying production code, this PR introduces: ### Test Infrastructure (4 new files) 1. **ScyllaDBTestEnvironment**: Test environment using ScyllaDB containers (319 lines) 2. **ScyllaDBTestContext**: Test context factory for source tests (162 lines) 3. **ScyllaDBSourceITCase**: Integration tests for source operations (414 lines) 4. **ScyllaDBConnectorITCase**: Integration tests for sink operations and batch formats (795 lines) ### Implementation Strategy To avoid modifying the existing Cassandra test infrastructure, the new ScyllaDB tests mirror the structure of their Cassandra counterparts. All ScyllaDB test files are standalone copies with ScyllaDB-specific configuration: - **ScyllaDBTestEnvironment** (319 lines): Duplicates `CassandraTestEnvironment` with ScyllaDB-specific container configuration (image: `scylladb/scylla:2025.1.4`, flags: `--reactor-backend=epoll --smp 1`, increased timeouts) - **ScyllaDBTestContext** (162 lines): Duplicates `CassandraTestContext` to provide type-compatible test context factory for source tests - **ScyllaDBSourceITCase** (414 lines): Duplicates `CassandraSourceITCase` with all 11 test methods running against ScyllaDB - **ScyllaDBConnectorITCase** (795 lines): Duplicates `CassandraConnectorITCase` with all 20+ sink and batch format tests running against ScyllaDB Original PR that got stale, can be found [here](https://github.com/apache/flink-connector-cassandra/pull/32) As suggested, inviting @dannycranmer or @zentol for a review.
