It tends to do very well for that. Storage and modifications are what is more expensive.. On Tue, Apr 12, 2016 at 8:07 PM, Gross, Daniel wrote: > Hi, > > > > I am new to Cassandra. > > > > I am wondering how well does Cassandra perform in e-commerce applications > that

Re: ntpd clock sync

NTP gradually speeds or slows the clock to arrive at actual time. So the clock still hits every second but 1s may really be 0.8s or 1.2s. In your case, it will sync up within a day. NTP is very clever so you never have newer files back-dated to be older than older files or vice versa. Spencer

Re: Files not removed after compaction

You can't delete by year unless tables are organized by year. For deleting tables, cassandra keeeps a copy of the file history which you can delete. Also, you could delete all the extra rows using CQL. On Wed, Jun 10, 2015 at 7:15 PM, Jeff Ferland j...@tubularlabs.com wrote: Compaction

Re: java exception on startup

We don't use thrift clients anymore, so it doesn't matter so much. But it's trying to read a file that doesn't exist or had bad perms. You'd have to get the source for the cassandra files anyway and try to figure out what file it's looking for. Probably some datafile that gets populated by
