With Repos you can create new or clone existing Git repositories in Azure Databricks, work with notebooks in these repositories, follow Git-based development and collaboration best practices, and integrate your CI/CD workflows with Repos APIs. Databricks Repos integrates with GitHub, Bitbucket, GitLab, and Azure DevOps. For details, see Git integration for Databricks Git folders and Repos API.

Increased timeout for long-running notebook jobs

You can now run notebook workflow jobs that take up to 30 days to complete. Previously, only notebook workflow jobs taking up to 48 hours to complete were supported. See Run a Databricks notebook from another notebook for more information.

Jobs service stability and scalability improvements

Aug 23-30, 2021: Version 3.53

The following changes increase the stability and scalability of the Jobs service:

  • Each new job and run is assigned a longer, unique, numeric, non-sequential identifier. Clients that use the Jobs API and depend on a fixed identifier length or sequential or monotonically increasing identifiers must be modified to accept identifiers that are longer, non-sequential, and unordered. The identifier type of int64 remains unchanged, and compatibility is preserved for clients that use IEEE 754 64-bit floating-point numbers, for example, JavaScript clients.
  • The value of the number_in_job field, included in the response to some Jobs API requests, is now set to the same value as run_id.

Note

This feature was delayed to February 2022.
