Unable to Start Serverless Compute in Databricks Free Edition

HariSankar — Fri, 11 Sep 2026 04:51:48 GMT

Hello everyone,

I am using Databricks Free Edition. I had not used my account for quite some time, and I recently logged in to start working again.

When I try to start Serverless Compute, I get the following error:
Cannot start serverless compute

Has anyone faced this issue recently? Is there any fix or workaround?

Could this be related to my account being inactive for a long time or a server-side problem?

Any help would be appreciated.

Thanks.

🚀 Quest 5 Submission: Intelligent RAG Knowledge-Base & Note-Taking Workspace

User_sky — Thu, 10 Sep 2026 18:17:24 GMT

Hi everyone! 👋

I am thrilled to share my final submission for Databricks AppKit Quest 5! I took the initial starter template and evolved it into a full-fledged, serverless Intelligent Knowledge-Base powered by Databricks Apps, Lakebase, and Foundation Model Serving.

Here is my project: 🔗 Live Deployed App: https://my-databricks-app-7474654586328503.aws.databricksapps.com/lakebase 🎥 YouTube Demo Video: https://youtu.be/n8nmNVhKEdg?si=leKi5vBQKmeYzBzJ

🌟 Going the Extra Mile (Training Voucher Eligibility)

To qualify for the Databricks training vouchers, I wanted to really push the boundaries of what this app could do. I implemented five significant custom features beyond the basic requirements:

Dual-Pane Markdown Engine: A fully functional Markdown editor with a live HTML preview tab to format notes professionally.
Focus Time Tracker: An integrated session stopwatch that tracks your active study/work time on a specific note and persists it directly to Lakebase PostgreSQL.
Bidirectional Note Linking: A cross-referencing system that allows users to link related notes together, creating a navigable knowledge graph.
Tokenized RAG Assistant: An AI agent that parses natural language questions (dropping stop words), searches Lakebase in real-time, summarizes insights, and provides clickable source citations.
Advanced Tagging & Priority: Visual priority badges and a dynamic tagging system for better organization.

🤖 Agents, Prompts & How I Built It

The Agent I Used: I used Gemini as my primary coding assistant and thought partner throughout this quest to iteratively build, debug, and deploy the application.

My Prompting Strategy: Instead of asking for everything at once, I used an Iterative Specification Prompting approach:

Template Injection: I fed the agent the DevHub RAG_TEMPLATE.md and told it: "Base the AI Assistant RAG on this template, and update my PLAN.md to reflect this new architecture."
Modular Planning: I prompted the agent to break the build into three distinct plans: 01-database-and-schema.md, 02-rag-assistant-service.md, and 03-frontend-ux.md.
Targeted Debugging Prompts: When I hit roadblocks, I used specific diagnostic prompts like: "My app fails to deploy with a '42501: must be owner of schema app' error in the SQL Editor. How do I fix the Service Principal permissions?" and "The RAG agent is doing an exact substring match and failing on natural language. Write a script to patch the backend SQL query to tokenize keywords instead."

How I Achieved the Tasks:

Schema Evolution: I first expanded the basic Lakebase schema to include tables for notes, tags, note_tags, and note_links with cascading deletes.
Frontend UI/UX: I completely redesigned the React frontend, adding the Markdown toggle (marked.parse), the interactive timer, and a dedicated RAG drawer.
Overcoming RAG Limitations: The biggest challenge was making the RAG agent understand conversational questions. I patched the backend to filter out stop-words (like "what", "is", "about") and dynamically build a parameterized ILIKE SQL query for the remaining tokens.
Deployment: After clearing up the local vs. Service Principal ownership conflicts in the Databricks SQL Editor by dropping the legacy tables, I successfully pushed everything to production using databricks apps deploy.

A huge thank you to the Databricks and AngelHack teams for putting together this incredible AppQuest. It was a fantastic hands-on experience with Lakehouse architecture!

Databricks Quest 4-(Deploy Your First Databricks App) success story

User_sky — Thu, 10 Sep 2026 14:30:28 GMT

🚀 Deployed Databricks AppKit + Lakebase: 2 Tricky Bugs & How I Solved Them!

Just deployed my first full-stack Databricks App using the AppKit Lakebase (PostgreSQL) template on serverless compute!

Using Gemini as an AI debugging agent via raw CLI logs in WSL, I diagnosed and resolved two critical roadblocks:

Bug 1: Missing DABs Variables (postgres_project)
- Fix: Added postgres_project, postgres_branch, and postgres_database directly under the variables: block in databricks.yml to unblock databricks apps deploy.
Bug 2: "Failed to Fetch Todos" (Silent Permission Denied 42501)
- Root Cause: Testing locally (npm run dev) first meant my personal user owned the app schema. The deployed app runs under a Service Principal, which was denied write access.
- Fix: Dropped the schema via DROP SCHEMA IF EXISTS app CASCADE; in the SQL Editor and redeployed. The Service Principal recreated the schema and took proper ownership!

💡 Pro-tip: When building with Lakebase, deploy first, test locally second so your App's Service Principal owns the schema from day one!

Databricks Account locked Issue

vikramraj — Wed, 09 Sep 2026 11:08:10 GMT

Hi Team

I am writing to raise a concern regarding continued difficulty accessing a Databricks free trial account using my company email address. This issue has persisted for an extended period and I would appreciate your assistance in resolving it. It would be really appreciable if anyone guide on this.

Details of the issue:

Company Email ID used for signup: [raj.sh@myCompanyName.com]
Issue duration: I have faced the same error for the past three weeks a screenshot is attached.
Partner: Even though we are partner with databricks
Error message (if any): [ "Limit Reached" I am getting: "You've reached today's limit and you've raised limit the maximum number of times this year . Your limit resets tomorrow" ]

I hope anyone of you considers this issue as we are working on a small POC to present a demo to internal clients. But we are completely blocked. Let me know if there is any way to unlock the account and use it , I am attaching a screenshot for refrence.

I await your response. Thank you for your understanding.

MetaData Framework for Multi-Level Silver Layer PK/FK Creation

SantiNath_Dey — Sun, 06 Sep 2026 14:02:56 GMT

Hi Team,
Our source data originates from MongoDB as hierarchical JSON and is ingested into our Silver layer, where it is already normalized into tabular structures. However, primary and foreign key constraints are not enforced during ingestion. We must establish and maintain PK/FK relational integrity post-loading through an automated post-processing step.The Challenge:The source system features a deep, multi-level parent-child tree hierarchy (e.g., emp -> emp_addr -> emp_addr_ofc). We require a metadata-driven modeling framework and script execution strategy to dynamically generate surrogate keys, resolve parent-child references top-down, and enforce relational integrity across all levels.

Please find below screen shot for your reference.

Recommendation for Data Reconciliation Frameworks (Legacy vs. Migrated Validation)

SantiNath_Dey — Sat, 05 Sep 2026 18:49:16 GMT

Hi Team,

We need to perform a data quality check between an legacy table and a newly migrated table generated by refactored code. Specifically, we want to validate:

Schema & Volumetrics: Total row counts, column counts, and column data type distributions (e.g., integer vs. string counts).

Aggregations & Hashes: Column-level aggregates (sum and average for numeric/decimal types) and overall table-level MD5 hashes.

Row-Level Integrity: Primary key-based row-level MD5 hash comparisons to detect individual discrepancies.

Although we currently use custom Python/PySpark scripts, is there an existing data reconciliation framework that can automate these checks and generate detailed mismatch reports for further analysis?

Not Able To Log In - Free Edition

RishiS — Tue, 18 Aug 2026 07:40:08 GMT

Hi Databricks Team,

I am not able to log in to my Databricks free edition account. I tried clearing my cache and logging in from incognito mode but I face the same error (screengrab attached) with Reference ID: d5284105-10d1-4b2f-88df-436ffd3efb72

I want to add context: I had an Azure free trial using the same email I use to log into Databricks free edition. I created a small Databricks project for my learning in this free subscription using the Azure Databricks service. The Azure subscription expired on 8th August 2026 and I have since deleted my Azure Subscription associated with this free account.

I raised a ticket with Databricks Support for this issue on August 5th and got a reference number - ref:!00D610JGc4.!500Vp0158S5Q:ref.However, even after following up, I still haven't received a response

I recently passed the Databricks Data Engineer Associate exam and wish to take the Databricks Data Engineer Professional and Context Engineer exams.
Kindly help me resolve this issue as I would like to access Databricks using the free edition for hands on practice.

Regards,

Issues with Custom Agents on Free Edition

taniumalloy — Sat, 15 Aug 2026 19:03:59 GMT

I have ran into a few issues while learning how to use Custom Agents in Databricks Apps that I would like to call out - both to help others and hopefully motivate platform improvements.

The only model that seems to work is databricks-meta-llama-3-3-70b-instruct, but I only found that out through a DataExpert.io YouTube video. It would be nice if the app templates would default to this or at least provide some guidance on the Free Edition limitations page.
Recent changes to MCP have caused issues with the default OpenAI Agents SDK app template. You have to manually add "mcp<2.0.0" to the dependencies in pyproject.toml to get it up and running.
The second message from the user starts to cause errors. I haven't figured out how to solve this, but it is something related to the format of the message chain. For example:

{ "detail": "Unhandled item type or structure: {'status': None, 'content': [{'text': \"Hello, it's nice to meet you. Is there something I can help you with or would you like to chat?\", 'type': 'output_text'}], 'role': 'assistant', 'type': 'message'}" }

Is there a cost for Databricks Workflow notifications or are they free?

MageshS — Mon, 20 Jul 2026 09:30:41 GMT

I couldn't find pricing information for Workflow/Job notifications anywhere in the Documentation or on the Pricing Page.

Is sending notifications for job run events (start, success, failure) via email, Slack, webhook, MS Teams, or PagerDuty a free feature, or is there some cost (DBU or otherwise) associated with it? Could someone confirm with an official source or doc reference? Thanks!
