voltDB性能

VoltDB has good performance with many connection in parallel. How can VoltDB deal with many connections? 

The high level of performance in VoltDB is due to the parallelism introduced by partitioning of data and each partition having its own query execution engine. Since each partition is guaranteed to have everything pertinent to a given partition key, there is no need for locking or latching. In addition, we have an internal connection context management module that takes care of managing the connections to queries and queueing mechanism. We have tested to 500K+ concurrent client connections.
