Difference between VoltDB and Warp 10

1. VoltDB :
VoltDB is distributed in-memory NewSQL RDBMS and an ACID-compliant RDBMS that uses a shared nothing architecture. This database was designed by Michael Stonebraker, Sam Madden, and Daniel Abadi. Initially VoltDB database included graphs for cluster throughput and latency as well as CPU and memory usage. VoltDB is based on H-Store and scales with the increasing core-per-CPU counts on multi-core servers.

2. Warp 10 :
Warp 10 is a TimeSeries DBMS specialized on timestamped geo data based on LevelDB or HBase. Server operating systems of Warp 10 is Linux, OS X, Windows. It is the most advanced Time Series Platform. Warp 10 is an open-source Geo Time Series Platform designed to monitor systems and the Internet of Things (IoT) and handle data coming from sensors.
