Versions#

This documentation covers a number of Starburst products around Presto. Products follow different release cycles and version numbering schemes. Some restrictions exist around combining different versions and ideally you use versions that are designed to be combined and are all documented together here.

List of versions#

LTS and STS releases#

Starburst Enterprise Presto (SEP) is available and maintained in long-term support (LTS) and short-term support (STS) releases. The following processes around Presto open source releases and SEP releases, availability and support apply.

General#

  • All Presto open source releases use a integer number such as 338.

  • A SEP release is created for each Presto open source release. It uses the source of the open source release, and adds the extensions and plugins.

  • Every release of SEP is created as an STS release first.

  • All STS releases use the Presto number with an appended -e, such as 338-e.

  • Some STS releases are promoted to LTS.

  • All LTS releases appended a patch number, such as 338-e.0, 338-e.1, 338-e.2, and so forth.

  • LTS and STS releases include all release artifacts such as tar.gz archive, rpm archive, container images, and additional tooling such as Kubernetes and CFT-related resources.

  • New features are never backported, but only become available in newer releases. As a result LTS users, who want to stay with LTS versions only, need to wait until the next LTS release is available, to gain access to new features. Alternatively you can change to use an STS version with the new feature and keep updating with each STS release until an LTS version is released.

STS releases#

  • Support for usage in production until the next STS release becomes available

  • Available shortly after each Presto open source release of the same version

  • No issues in the release are fixed as patches to that release, any changes or fixes are incorporated in the next release. For example, a problem in 333-e is fixed and made available in 334-e, 335-e, or whenever a fix is available.

LTS releases#

  • Support for usage in production for 12 months

  • Only available for selected Presto open source releases

  • Limited, low number of release per year, at most one release per quarter

  • Some issues are backported to the release and made available as patch releases. For example, a problem in 332-e.2 is fixed and released in 332-e.3

The following resolutions for issues are backported:

  • Critical security fixes

  • Select fixes for critical defects that affect production usage, and for which no workaround is available. This may include incorrect results, severe performance regressions, and stability issues. The decision to backport such fixes is made by Starburst in collaboration with affected customers, if necessary.
