Queue-like data structures are known to be one of the worst anti patterns for Cassandra: http://www.datastax.com/dev/blog/cassandra-anti-patterns-queues-and-queue-like-datasetsOn Sat, Feb 22, 2014 at 4:03 PM, Jagan Ranganathan <firstname.lastname@example.org> wrote:
Hi,I need to decouple some of the work being processed from the user thread to provide better user experience. For that I need a queuing system with the following needs,
- High Availability
- No Data Loss
- Better Performance.Following are some libraries that were considered along with the limitation I see,
- Redis - Data Loss
- ZooKeeper - Not advised for Queue system.
- TokyoCabinet/SQLite/LevelDB - of this Level DB seem to be performing better. With replication requirement, I probably have to look at Apache ActiveMQ+LevelDB.After checking on the third option above, I kind of wonder if Cassandra with Leveled Compaction offer a similar system. Do you see any issues in such a usage or is there other better solutions available.Will be great to get insights on this.Regards,Jagan
