+ test("arrow zstd compression round-trips through the JDBC client") {
+ // End-to-end coverage of the compressed Arrow IPC path: the engine
compresses batches with
+ // the upstream-named codec config, and the JDBC client transparently
decompresses them from
+ // the batch body compression metadata (no server-side codec hint on the
wire).
Review Comment:
Addressed. I renamed the existing test to engine-side coverage and added a
server-side test covering JDBC client <=> Kyuubi server <=> Spark engine.
