Highlights

Version number scheme change

The version numbering scheme for Imply has changed in this release. The version numbering scheme reflects a shift to a monthly release cadence.

2020.11 is a Short Term Support release. As of this release, Imply releases fall into one of two categories: Long Term Support (LTS) and Short Term Support (STS).

Imply Product Long Term Support (LTS) releases are complete, stable versions of our products. They are subject to general bug fixes for one year and to security bug fixes for two years after release, but do not receive features enhancements. They are best suited to production environments that require stable operation and do not require the latest features.

Releases that are not subject to long term support — that is, Short Term Support (STS) releases — include the latest features, including experimental features. STS releases occur on a regular basis. They are not subject to bug fixes, but may receive critical security patches. In general, to receive the latest bug fixes, you should upgrade to the latest monthly release.

Note the following additional highlights in 2020.11.

Druid highlights

Imply 2020.11 includes updates for Druid that include:

  • A refreshed style for the web console
  • The ability to use an expression for the timestamp column during ingestion. For example, you can concatenate multiple fields to comprise the timestamp Druid parse time field using expression
  • Improved SQL query error handling

See Druid Changes for other Druid updates.

Platform highlights

Imply Cloud now offers additional AWS EC2 m5 series types as deployment options for master nodes, including m5.xlarge, m5.2xlarge, and m5.4xlarge.
