MLflow Model Registry Webhooks on Databricks (Public Preview)

January 31, 2022

You can now use webhooks to listen for MLFlow Model Registry events and trigger actions based on them. For example, you can use webhooks to automate and integrate your machine learning pipeline with existing CI/CD tools and workflows, trigger CI builds when a new model version is created, or notify your team members through Slack when a model transition to production is requested. For details, see MLflow Model Registry Webhooks on Databricks.

Breaking change: cluster idempotency token cleared on cluster termination

January 26, 2022

Beginning February 14th, 2022, Databricks cluster management will be modified to clear idempotency tokens when a cluster is terminated. This change is required to enable improvements to cluster management uptime guarantees.

You must update any clients or scripts that rely on an idempotency token to persist after terminating a cluster. If you submit a create cluster request using an idempotency token not assigned to a non-terminated cluster in the workspace, a new cluster is created.

The following illustrates the behavior before this change:

createCluster(idempotencyToken = tokenA) // launches new cluster A
terminateCluster(cluster A) // idempotency token tokenA is still associated with the terminated cluster A
startCluster(cluster = A)

createCluster(idempotencyToken = tokenA) // returns the currently running cluster A

The following illustrates the new behavior:

createCluster(idempotencyToken = tokenA) // launches new cluster A
terminateCluster(cluster A) // idempotencyToken token tokenA is cleared from the cluster A configuration
startCluster(cluster A)

createCluster(idempotencyToken = tokenA) // launches new cluster B

You can now view in real time currently running and recently completed job runs in the Job runs page in the Databricks jobs user interface. See View recent job runs.

Use Markdown in Databricks Repos file editor

January 25-31, 2022: Version 3.64

The Databricks Repos file editor can now render markdown. For details, see Work with non-notebook files in a Databricks repo.

Improved cluster management for jobs that orchestrate multiple tasks

January 24, 2022

You can now reuse job clusters in your jobs that orchestrate multiple tasks. Cluster reuse allows you to reduce cluster resource usage by using a single cluster to run multiple tasks in a job run. See Jobs.

Add or rotate the customer-managed key for managed services on a running workspace

January 25, 2022

Adding a customer-managed key (CMK) for managed services enables encryption with your customer-managed key for notebook source, secrets, and Databricks SQL query history. Previously, you needed to add the key when you created the workspace. You can now add this key on a running workspace or rotate (update) the key. Note that Databricks does not directly encrypt the data with the customer-managed key (CMK). Databricks uses both the CMK and the Databricks managed key (DMK) that is unique to your workspace to encrypt the Data Encryption Key (DEK). Databricks uses the DEK to encrypt the workspace’s managed services persisted data. Adding a CMK does not re-encrypt data that does not use a CMK. Rotating the CMK does not change the DEK. See Add or rotate a customer-managed key for managed services on a running workspace.
