  • Escalation is a way to bring extra attention to a Severity 1 incident. When a customer notifies Support that they wish to escalate, a review call will be set up with VoltDB Support, the VP of Engineering and any appropriate resources to develop an action plan for issue resolution.
  • A Hot Fix is a patch release to the customer’s current version. Hot fixes will be provided only for Severity 1 incidents which cannot be alleviated with a workaround, or when a customer is unable to upgrade to the next release.

VoltDB Long-Term Support (LTS) releases are supported for 3 years, with extended support available. All non-LTS releases are supported for 1 year.

Customers should plan to upgrade before their version reaches End-of-Life. The LTS program is designed to provide a longer term to allow for planning and choice when deploying or scheduling upgrades.

Customers who continue running VoltDB software that is past End-of-Life will still receive support, but any defects that require a fix would be corrected in an update to an LTS release and the customer will need to upgrade to apply the correction.
