The piece recommends building an asset inventory in October, before Black Friday change freezes make fixes harder. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### When does the Databricks Genie MCP beta endpoint /api/2.0/mcp/genie get shut down? The beta endpoint /api/2.0/mcp/genie is deprecated and will be sunset on October 31, 2026. Anything still pointing at it must move to the new generally available endpoint, system.ai.genie_one_mcp, which runs through Unity Gateway and enforces Unity Catalog permissions on every request from MCP clients like Claude, ChatGPT, or Cursor. _Track endpoint sunsets like this on daily.dev so agent integrations keep working after the cutover._ ### What happens to a Databricks service principal's OAuth client secret if it is not used for a while? Databricks now automatically deletes a service principal's OAuth client secret once it has gone 90 days without use, a rule introduced September 16, 2026, mirroring the existing 90-day revocation for unused personal access tokens. This mainly breaks low-frequency automation like quarterly exports or annual tax pulls, since daily jobs never go idle long enough to trigger it. _Developers auditing seasonal jobs and stale credentials can follow platform changes like this on daily.dev._ ### Does deleting a Databricks Unity Catalog pipeline also delete its tables? No, as of a September 25, 2026 change, deleting a Unity Catalog pipeline using the default publishing mode retains its materialized views, streaming tables, and views by default; they remain queryable but stop updating. To delete the tables along with the pipeline, the delete API request must explicitly set cascade to true. _Teams cleaning up pipelines without leaving stale dashboards behind can track platform defaults like this on daily.dev._ ## Similar posts on daily.dev - [GitHub Models is being fully retired on July 30, 2026](https://daily.dev/posts/github-models-is-being-fully-retired-on-july-30-2026-bz8saavyw) · GitHub Changelog · 43 upvotes · 5 comments - [Real-Time AI Pipelines: Building a Kafka \+ Kubernetes \+ Databricks Stack for Agentic AI Systems](https://daily.dev/posts/real-time-ai-pipelines-building-a-kafka-kubernetes-databricks-stack-for-agentic-ai-systems-qoytpduhq) · Medium · 0 upvotes · 0 comments - [How a major freight railroad scaled pipeline creation with Genie Code](https://daily.dev/posts/how-a-major-freight-railroad-scaled-pipeline-creation-with-genie-code-mb82nbwwx) · databricks · 0 upvotes · 0 comments --- Tags: [#backend](https://daily.dev/tags/backend), [#mcp](https://daily.dev/tags/mcp), [#databricks](https://daily.dev/tags/databricks), [#oauth](https://daily.dev/tags/oauth), [#unity-catalog](https://daily.dev/tags/unity-catalog) [View this post on daily.dev](https://daily.dev/posts/databricks-october-deadlines-will-break-the-pipelines-nobody-watches-pztznyweb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Databricks’ October Deadlines Will Break the Pipelines Nobody Watches","url":"https://daily.dev/posts/databricks-october-deadlines-will-break-the-pipelines-nobody-watches-pztznyweb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/databricks-october-deadlines-will-break-the-pipelines-nobody-watches-pztznyweb"},"datePublished":"2026-10-04T11:49:41.633Z","dateModified":"2026-10-04T12:14:49.033Z","description":"Several Databricks platform changes from the September 2026 release notes carry October and November deadlines and specifically hit infrequently-used...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/3ebac79b3b24b3c37a900474d34bcec9?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/3ebac79b3b24b3c37a900474d34bcec9?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Medium","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Medium","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/medium","url":"https://daily.dev/sources/medium_js"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/databricks-october-deadlines-will-break-the-pipelines-nobody-watches-pztznyweb","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"backend,mcp,databricks,oauth,unity-catalog","timeRequired":"PT7M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Medium","item":"https://daily.dev/sources/medium_js"},{"@type":"ListItem","position":3,"name":"Databricks’ October Deadlines Will Break the Pipelines Nobody Watches"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/databricks-october-deadlines-will-break-the-pipelines-nobody-watches-pztznyweb#faq","mainEntity":[{"@type":"Question","name":"When does the Databricks Genie MCP beta endpoint /api/2.0/mcp/genie get shut down?","acceptedAnswer":{"@type":"Answer","text":"The beta endpoint /api/2.0/mcp/genie is deprecated and will be sunset on October 31, 2026.
