I have run the test using Cassandra Spark connector and modified Spark (with this patch). The test passes (without modification to Cassandra Spark connector or client code).

@sunchao Please take another look.

@sunchao https://github.com/tedyu/spark/runs/8459534296 shows that all tests have passed.

@sunchao Can this PR be merged ?

There was a proposed change deadlock_detector.cc . However, it seems no current test goes through that code path. Edit: I am looking closer at the tests since the test stability...

From commit c6b90bbb173be7011498fe09d0e63018fecf6f85 3) Disable batching if the table contains non-FK trigger as per the following [change](https://github.com/yugabyte/yugabyte-db/commit/7c428da49ce9009df8faf9788c53c9c71cb7178b). which seems to apply to the schema given above.

Please turn `yb_enable_upsert_mode` off for large data loading. cc @paullee-yb

I looked at related code. Initial thought is adding new func to ServerGroupsInterface which exposes the 403 error. Let me see if I can find better approach.

I looked at `pg_regcomp` When it returns, `freev` is called which would in turn call `rfree`. There doesn't seem to be memory leak.
