Is Databricks Light Runtime Discontinued?

[venkad]

The last Databricks Light runtime release was 2.4 Extended Support. There was no Light version for Spark 3.x. Is Databricks Light runtime discontinued? If not, when we can expect the next DBR Light version?

Hi @Venkadeshwaran K​,

Databricks Light 2.4 Extended Support will be supported through April 30, 2023.

It uses Ubuntu 18.04.5 LTS instead of the deprecated 16.04.6 LTS distribution used in the original Databricks Light 2.4.

Ubuntu 16.04.6 LTS support ceased on April 1, 2021.

Support for Databricks Light 2.4 ended on September 5, 2021, and Databricks recommends that you migrate your Light workloads to the extended support version as soon as possible.

This article lists all Databricks runtime releases and the schedule for supported releases. For more information about the Databricks Runtime support policy and schedule, see Databricks runtime support lifecycle.

Hi @Venkadeshwaran K​, I looked around, and it does look like there won't be future light runtimes. We can't hire enough engineers to maintain and develop everything, and light is one of the casualties of that.
