> ThriftServerQueryTestSuite runs 800+ SQL golden file tests sequentially in a
> single SparkSession. The default spark.cleaner.periodicGC.interval is 30
> minutes, which is too infrequent for the memory pressure in this long-running
> suite (~50 min). This causes intermittent OOM (java.lang.OutOfMemoryError:
> Java heap space) during scalar subquery tests, with 100+ failed page
> allocations (64MB each).
> Reduce the periodic GC interval to 60 seconds for this test suite to allow
> more frequent garbage collection and prevent memory buildup.
