Re: why dose it still have to seach in SSTable when getting data in memtable in the read flow？

Hi, Cassandra uses last-writetime-win strategy. In memory data doesn't mean it is the latest data due to custom write time, if data is also in Sstable, Cassandra has to read it and reconcile. Jasonstack On Mon, 27 Mar 2017 at 7:53 PM, 赵豫峰 wrote: > hello, I get the message

Re: Does anyone store larger values in Cassandra E.g. 500 KB?

1. usually before storing object, serialization is needed, so we can know the size. 2. add "chunk id" as last clustering key. Vikas Jaiman 于2016年10月21日周五 下午11:46写道： > Thanks for your answer but I am just curious about: > > i)How do you identify the size of the object

StatusLogger is logging too many information

Hi, Currently StatusLogger will log info when there are dropped messages or GC more than 200 ms. In my use case, there are about 1000 tables. The status-logger is logging too many information for each tables. I wonder is there a way to reduce this log? for example, only print the thread pool
