Description RethinkDB is an open-source, scalable, distributed database built to store JSON documents. VoltDB is an ACID-compliant OLTP database that can process millions of transactions per second on commodity servers that are loosely connected over a fast network. It is a highly scalable alternative to legacy SQL databases such as Oracle and MySQL. VoltDB is accessed using SQL, the industry standard data language, and is also accessible using popular key-value and document-style interfaces.
