scalardb-phoenix

A storage implementation of Scalar DB using Apache Phoenix. Apache Phoenix is an add-on for Apache HBase that provides a programmatic ANSI SQL interface.

Limitation

• The atomic unit of Scalar DB with the Cassandra storage implementation (default) is a partition. However, the atomic unit of this storage implementation is PartitionKey + ClusteringKey, which is difference from the default storage implementation (Cassandra).
• Conditional update with multiple conditions is not supported.
