Comparison with Riak,

[Kishorekumar Neelamegam]

Hey

We currently use Riak, which has clustering(HA) available. I can scale to any number of nodes in a simple way.

How do you ScyllaDB compare to Riak ? 

[Tzach Livyatan]

The main different between Scylla (and Cassandra) to Riak, is Scylla is Key->Key->Value, while the Riak is Key->Value.

This apply difference in data modeling which I can expend on if you wish.

Scylla HA is base on Cassandra HA mechanisms, including the concepts of replication factor, consistency level, symmetrical nodes, etc.

Baso did a decent job describing[1] the difference between the Riak and Cassandra, which apply to Scylla for the most parts, with the exception of Merkle trees, which Scylla have a slightly different take on than Cassandra.

Also, Cassandra supports Geo-Replication out of the box, Basho requires commercial license for this.

Is Geo-Replication fully implemented in Scylladb right now ?

Do you mean support for replication across multiple data centers? If so, that indeed supported.

Avi,

Is Geo Replication Opensource ? Or provided  under Enterprise support package ? 

[Avi Kivity]

It is open source and available in the standard package.
