The runtime overflow guard test (testLargeIndexSummary) required ~2 GiB of off-heap memory to trigger the Integer.MAX_VALUE boundary in IndexSummaryBuilder.maybeAddEntry. SafeMemoryWriter's 50% buffer growth strategy caused ~5 GiB peak memory during reallocation (old + new buffer), exceeding CI medium node limits (3.5-5 GB). Extract the hardcoded Integer.MAX_VALUE threshold in IndexSummaryBuilder into a @VisibleForTesting field (maxEntriesSize), allowing the test to exercise the same guard logic with a 2 MB threshold instead. Rename both large summary tests to reflect their distinct code paths: runtime truncation vs constructor-initiated downsampling. patch by Sam Lightfoot; reviewed by Brandon Williams,Dmitry Konstantinov,Michael Semb Wever for CASSANDRA-20599 |
