Hi folks, Cassandra JIRA is huge, active, and ever-changing. It's easy to miss tickets you may care about, or if you want to start contributing, sometimes it's hard to know where to start. I'm going to make an attempt to pick a few dozen JIRAs each week (or month?) that would benefit from some more eyeballs - if you have any tickets that you feel haven't gotten the attention they deserve, feel free to add them to the list.
Topics for discussion (not necessarily a "go write a patch" type ticket, but things that could use interested parties discussing options): https://issues.apache.org/jira/browse/CASSANDRA-12944 - Internal diagnostic events. Pretty involved proposal attached. https://issues.apache.org/jira/browse/CASSANDRA-12912 - Warnings when the superuser logs in https://issues.apache.org/jira/browse/CASSANDRA-9608 - Get Cassandra ready for java9 - if anyone has time to help find issues with jdk9, the oracle team asked for feedback some time ago, I'm not sure if they're still interested, but it'd be good for us to identify issues anyway. https://issues.apache.org/jira/browse/CASSANDRA-13315 - talks about using more meaningful names for consistency levels (as aliases) https://issues.apache.org/jira/browse/CASSANDRA-13241 - talks about dropping default chunk size for better IO performance (may have a blocking subtask of making compression info more efficient before we do it, but you may still be interested in the discussion) Patches that could use a reviewer: LHF (MAY be suitable for someone who is a solid programmer, even if they're not super familiar with Cassandra internals - even if you're not a regular contributor, you can review and +1 if you're confident that the fix is correct and has been reasonably tested - see the 'How to review' checklist http://cassandra.apache.org/doc/latest/development/how_to_review.html ): https://issues.apache.org/jira/browse/CASSANDRA-13307 - Making CQLSH downgrade protocol version automatically https://issues.apache.org/jira/browse/CASSANDRA-13067 - AWS EFS fixes (presents as huge filesystem, overflows internal variables) https://issues.apache.org/jira/browse/CASSANDRA-13263 - Incorrect ComplexColumnData hash code implementation https://issues.apache.org/jira/browse/CASSANDRA-12719 - Typo in docs examples Proposed New features without a reviewer: https://issues.apache.org/jira/browse/CASSANDRA-13269 - Snapshot support for secondary index https://issues.apache.org/jira/browse/CASSANDRA-13270 - Add function hooks to deliver Elasticsearch as a Cassandra plugin https://issues.apache.org/jira/browse/CASSANDRA-13304 - Add checksumming to the native protocol https://issues.apache.org/jira/browse/CASSANDRA-13268 - Add 2i to static columns Enhancements without a reviewer: https://issues.apache.org/jira/browse/CASSANDRA-9989 - Optimize BTree builder https://issues.apache.org/jira/browse/CASSANDRA-9988 - BTree Leaf-only iterator https://issues.apache.org/jira/browse/CASSANDRA-12837 - Multithreaded support for rebuild_index Bugs without a reviewer: https://issues.apache.org/jira/browse/CASSANDRA-13323 - IncomingTcpConnection closed on single bad message https://issues.apache.org/jira/browse/CASSANDRA-13020 - Hint delivery fails when prefer_local enabled The new "official" docs sections that could use some contributors! This may be the lowest barrier to entry if you want to get involved - the docs are kept in source control ( https://github.com/apache/cassandra/tree/trunk/doc ) , so we can change them with patches against those files submitted through JIRA. No github pull requests, please, just submit a patch on JIRA (see https://issues.apache.org/jira/browse/CASSANDRA-13160 or https://issues.apache.org/jira/browse/CASSANDRA-12449 as examples): Some examples that are just stubbed out: http://cassandra.apache.org/doc/latest/architecture/index.html http://cassandra.apache.org/doc/latest/architecture/dynamo.html http://cassandra.apache.org/doc/latest/architecture/storage_engine.html http://cassandra.apache.org/doc/latest/data_modeling/index.html http://cassandra.apache.org/doc/latest/operating/read_repair.html http://cassandra.apache.org/doc/latest/operating/repair.html http://cassandra.apache.org/doc/latest/operating/hints.html http://cassandra.apache.org/doc/latest/operating/backups.html http://cassandra.apache.org/doc/latest/operating/bulk_loading.html I'll try to do this regularly. Again, if you have any tickets you feel need attention, please reply! - Jeff
