Few things worth mentioning in the cassandra world this week: 1) If you somehow missed the cassandra-on-the-rocks(db) thread, you should check it out: https://lists.apache.org/thread.html/6860e04d6ff58fb0f65fdaa6e9b53aedf0d432a88bed32107e7ccec8@%3Cdev.cassandra.apache.org%3E . FB/Instagram are proposing pluggable storage engines to make using alternate backends (like RocksDB) possible/supported. This is common in other databases (think MySQL with MyISAM+InnoDB), but is new to Cassandra. If you have a strong opinion, you should reply to that thread.
2) There's a ticket on trying to be more clever with storage/replication factors @ https://issues.apache.org/jira/browse/CASSANDRA-13442 , that's probably interesting if you're storage-bound. 3) The diagnostic events ticket ( https://issues.apache.org/jira/browse/CASSANDRA-12944 ) has some interesting tests added ( https://github.com/spodkowinski/cassandra/blob/WIP-12944/test/unit/org/apache/cassandra/examples/HintsServiceEventsExampleTest.java ). Maybe that's a month old, but it's an interesting concept. Corentin asked for a reviewer in IRC for: https://issues.apache.org/jira/browse/CASSANDRA-13432 And since he asked, I figured other people may want some reviews too. Here are a few others that are PA and no reviewer: https://issues.apache.org/jira/browse/CASSANDRA-13467 (backporting a logging change from 3.6) https://issues.apache.org/jira/browse/CASSANDRA-10968 (snapshotted manifests are wrong) https://issues.apache.org/jira/browse/CASSANDRA-13434 (rpm fixes) https://issues.apache.org/jira/browse/CASSANDRA-13435 (rpm fixes) https://issues.apache.org/jira/browse/CASSANDRA-13067 (using aws EFS will fail on startup due to long overflow) Less LHF'y, but potentially very important: https://issues.apache.org/jira/browse/CASSANDRA-13262 (incorrect results when including the same column in cql twice) https://issues.apache.org/jira/browse/CASSANDRA-13425 (nodetool refresh maintains levels) https://issues.apache.org/jira/browse/CASSANDRA-12126 (CAS inconsistencies on read - also includes a lot of CAS testing) https://issues.apache.org/jira/browse/CASSANDRA-11995 (commitlog replay bug) https://issues.apache.org/jira/browse/CASSANDRA-11521 (streaming for bulk reads) - Jeff
