+1 to Tupshin's proposal: 10k nodes (massive clusters) really is the next frontier. I don't expect the vnodes to add that much to the gossip dissemination as the tokens per-node are sent out only a handful of times (when a node joins the ring, mostly). Without having hard data to back myself up, I

Hi Haryadi, Personally I'd love to see your approach extended to test up to 10K nodes, or so. There are not too many known instances of scaling past 1000 nodes, and as the need for scale grows, and as scale out hardware becomes more commonplace (high density, but with lots of small servers...aka

Thanks, Benedict. Is this only true as of 3.x (new storage engine), or was the equivalent efficiency also true with 2.x? It would be good to have an explicit statement on this efficiency question in the spec/doc since the spec currently does say: "The option also *provides a slightly more compact

As I understand it "COMPACT STORAGE" only has meaning in the CQL parser for backwards compatibility as of 3.0. The on disk storage is not affected by its usage. > On Apr 11, 2016, at 3:33 PM, Benedict Elliott Smith > wrote: > > Compact storage should really have been named "not wasteful stora

Hi Jonathan, Thanks for the reply! We don't need a patched version of Cassandra. Specifically, this is what we'd like to get help from you if possible: Cassandra devs: "Here are recent JIRA entries that discuss scale-dependent bugs: CASSANDRA-X, -Y, -Z (where XYZ are JIRA bug#)" Our side: We

2016-04-11 Thread Benedict Elliott Smith
Compact storage should really have been named "not wasteful storage" - now everything is "not wasteful storage" so it's void of meaning. This is true without constraint. You do not need to limit yourself to a single non-PK column; you can have many and it will remain as or more efficient than "comp

COMPACT STORAGE in 4.0?

2016-04-11 Thread Jack Krupansky
My understanding is Thrift is being removed from Cassandra in 4.0, but will COMPACT STORAGE be removed as well? Clearly the two are related, but COMPACT STORAGE had a performance advantage in addition to Thrift compatibility, so its status is ambiguous. I recall vague chatter, but no explicit depr

The answer will depend on how conservative you are. The most conservative choice overall would be to go with the 2.2.x line. 3.0.x if you want to the new nice and shiny 3.0 things, but can tolerate some risk (the branch has a lot of relatively new core code, and hasn’t yet been tried out by as

As an operator, I’d imagine it’s mostly the same as always - stability will vary by workload, so test with your workload until you’re confident. If x.y.Z where Z >= 6 was basically the guideline most people used before, then it’s probably worth considering 3.5 and 3.7 as worth testing in your sp
