VoltDB 2.0 was released last week and I wanted to take this opportunity to summarize the important new features, including enhancements for database durability and recovery; key performance and interoperability improvements; and many enhancements geared at helping developers use VoltDB productively. Here are the details:

• Durability and recovery.  Version 2.0 introduces a new feature called Command Logging that allows VoltDB databases to be fully recoverable in the face of severe failures caused by hardware and software crashes.  Available in VoltDB Enterprise Edition, Command Logging ensures that every transaction applied to a VoltDB database is separately logged to disk.  Following a

In the last couple of releases of VoltDB, we’ve made steady improvements to our Export feature. Export allows you to build into your VoltDB applications an automatic flow of data from VoltDB to companion datastores (for example, to an analytic database).

VoltDB provides powerful interoperability features that allow you to select, enrich and distribute data to downstream file systems and databases.

The target for exporting data from VoltDB may be another database, a repository (such as a sequential log file), or a process (such as a system monitor or accounting system). No … Read more
