It's been a busy summer here at VoltDB! Since spring the VoltDB Engineering team has released VoltDB four times (we're operating on 3 week sprints) and delivered numerous product and performance enhancements.

Some of the major features we've recently released include:

  • Pause-less rejoin of failed nodes. Failed nodes can now be rejoined to the k-safe cluster without significant impact to the operational throughput of the cluster. This feature is available in the Enterprise edition of VoltDB.
  • Significant performance improvements around ad hoc SQL, which is SQL executed outside of stored procedures, via the @AdHoc system procedure invocation or through JDBC.   Some of our internal workloads saw three orders of magnitude improvement in ad hoc throughput.
  • SQL LIKE support.  Provides the ability to search for a specified pattern in a column.
  • CSV Loader.   The ability to load data into VoltDB from a text file containing comma-separated tabular values.
  • New PHP Client. A new lightweight C-extension-based PHP client with a streamlined interface.

We've also introduced numerous other features including:
