Hi,
We are evaluating NoSQL datastore for our project. We have short listed few among which Cassandra and OrientDB are one of the candidates. Our key requirements are...
1> Very low single read and write latency (< 5 ms)
2> Very low NON-KEY single read and write latency (< 5 ms). In Cassandra we are allowed to denormalize and store data in multiple tables.
3> Data size in each table - 50,000M rows
4> Auto sharding/rebalancing
5> Multi-data center replication support
6> Product should be very very stable
7> Should be Apache 2 Licensed where ALL the above key features are available in the FREE/Community edition.
Can anyone help with little details around these criteria. Any pointer to benchmark data of both done together would also help.
Regards,
LP
