Re: [VOTE] Release Apache Cassandra 4.0.0 (third time is the charm)
+1 (nb) for Charmed Cassandra. Very proud of this community for holding to the commitment to quality. A lot of us were there at ApacheCon 2019 in Las Vegas. Sitting on the hallway carpet at the Flamingo, debating what a release should look like for the project. Here we are!

Re: [DISCUSS] CEP-11: Pluggable memtable implementations
> CEP indicates the flushing behavior is suddenly more tied to the Memtable implementation level rather than being configurable at the table level The specific things that change with the proposal are: - Flushes are supplied with a reason (e.g. memory full, schema change, prepare to stream). - The memtable can reject a flush request. - The logic to initiate "memory full" and "period expired" flushes moves to the memtable where it conceptually belongs. Is the latter what worries you? For reusability, the current logic is extracted in a base class that the skiplist/trie/7282 implementations derive from. > I'm not sure if the "isDurable" + "shouldSkip" is interesting instead of "shouldWrite"(etc). But I also wonder in cases where point-in-time restore is required how one could achieve it without a commit log(can persistent memory memtable be rolled back?). That's exactly the reason why the two flags are separate. To use PITR, you use the commit log but make sure that it does not treat the segments covered by the persistent memtable as dirty(i.e. writesAreDurable but not writesShouldSkipCommitLog); commit log segments are written only to be archived, and PITR restores a memtable snapshot and applies the mutations after it. Am I misunderstanding the question? > Although I do feel like persistent memory exceptions make stuff more complex. The persistent memtables were the reason that drove this functionality, but think about it also as an easy way to do pluggable storage engines. I may not be up to date with the consensus in the community on this, but I don't see us investing the effort to have fully-fledged pluggable storage engines of the CASSANDRA-13475 type any time soon. To make the memtable a storage engine you need two things: - an opt out of flushing, so that the memtable is the only component that serves reads, - an opt out of the commit log, so that the memtable is the only component that serves writes, plus some solutions for the secondary uses of sstables (streaming) and commit log (PITR, CDC). The proposal gives it that, with a little more control than just opt-out. It can work for the pmem (opt out of both) and rocksdb (opt out of flushing only) use cases, but for me it will also be useful to experiment with a memtable that includes its own version of a commit log (opt out of commit log only).
