-------------------------------------
Summary: Fix Accord bugs
Key: CASSANDRA-21813
URL: https://issues.apache.org/jira/browse/CASSANDRA-21813
Project: Apache Cassandra
Issue Type: Bug
Reporter: Alan Wang
Assignee: Alan Wang
- NativeLibrary.trySkipCache does not drop data properly for files larger than
2 GiB
- FileHandle.dropPageCache can drop hot data
- SSTableReader.trySkipFileCacheBefore was using uncompressed position
- TxnRead select and merge can produce wrong results resulting in incorrect
reads
- When CAS has a condition on a regular column and a static column and the
regular column does not exist, the value for the static column is treated as
NULL in Accord
- Exists for Accord LWTs checked whether the CAS read returned any data for the
partition, not whether the targeted row (its clustering, or the static row)
existed
- Fix conditional batch statements for Accord, in the case when doing a
partition level delete or range deletion deletes shadow subsequent inserts
which is different from the behavior with Paxos
- For operations that we do an auto read on and the row the statement targets
is missing, the static row’s read is dropped causing incorrect results
