Re: Question upon gracefully restarting c* node(s)

The sequence does have some objective benefits - especially stopping transports and then gossip, it tells everything you’re going offline before you do, so requests won’t get dropped or have to speculate to other replicas. -- Jeff Jirsa > On Jan 7, 2018, at 7:22 PM, kurt greaves

Re: Question upon gracefully restarting c* node(s)

None are essential. Cassandra will gracefully shutdown in any scenario as long as it's not killed with a SIGKILL. However, drain does have a few benefits over just a normal shutdown. It will stop a few extra services (batchlog, compactions) and importantly it will also force recycling of dirty

Re: 3.0.15 or 3.11.1

Hi, Can you please provide dome JIRAs for superior fixes and performance improvements which are present in 3.11.1 but are missing in 3.0.15. In addition,could you also provide the probable implications of the open memory leak issue in Cassandra 3.11. CASSANDRA-13929: BTree$Builder /

Re: Rebuild to a new DC fails every time

If you're on 3.9 it's likely unrelated as streaming_socket_timeout_in_ms is 48 hours. Appears rebuild is trying to stream the same file twice. Are there other exceptions in the logs related to the file, or can you find out if it's previously been sent by the same session? Search the logs for the

Re: 3.0.15 or 3.11.1

Re: 3.0.15 or 3.11.1

Thanks Guys! Sorry for the late reply. I'm interested in TWCS where I understand is more stable in 3.11.1 than in 3.0.15, tombstone compaction and slow logs. I don't plan to use MVs and SASI in the near future, as I understand are not Production ready. Is it okay to use the above features?
