Broken x-axis sort order in combo chart

treesloth — Fri, 11 Sep 2026 18:57:32 GMT

Hello. I am using the Combo Chart to create a Pareto visual. I have an SQL query with built-in ordering, with output like:

	category	sort_order	category_count	cumulative_pct
1	SQL	1	52	29.9
2	Python	2	39	22.4
3	R	3	21	12.1
4	.Net	4	16	9.2
5	Bash	5	8	4.6
6	All Others	6	38	21.8

That's not the whole dataset, of course. It's more complicated, but that's idea. I'd be happy to post the script if it would help. Anyway, I created (or, really, Genie created) a combo chart based on the data. It worked, and the chart displayed in the same order on the x-axis as the sort_order in the data. I liked it, but realized I needed to modify it a little. That was successful, but the sorting is now ruined. I didn't intentionally apply a sort, now it goes by 'category' alphabetical order.

So, at some point, it's as though the visualization editor applied no sort at all... it just went by the SQL order. Now it does apply a sort order. FWIW, the editor does currently have an alphabetical ordering applied:

So, it's like I need to somehow tell it to use no ordering at all. Maybe. Or maybe it doesn't work like that at all. But how do I get it to use sort_order again like it did before? Or is something else going on here that I don't understand?

Edit: More information in one place

What are the current eligibility requirements for the Databricks Partner Champion Program?
You need to meet the prerequisites, including 2 Fundamental certifications (Data + Generative AI Fundamentals), 1 Associate-level certification, and 1 Professional-level certification. For EMEA candidates, the employer must also be a Select or Elite CSI partner. The program is invitation/nomination-only.
Which Databricks Partner Academy courses or learning paths should I complete?
If you already have the required certifications, you do not need to complete any special Partner Academy courses before nomination.
Are there specific instructor-led courses or badges, such as Solution Architect Essentials, that are required?
Yes. Solution Architect Essentials is required, but it is available only after you are invited/accepted into the program.
Which paid Databricks certifications are recommended or required for the Partner Champion journey?
See point 1 — you need 2 Fundamental certifications, 1 Associate certification, and 1 Professional certification.
Should I focus on Data Engineering, Data Analytics, Machine Learning, Generative AI, or Solution Architecture certifications?
Choose the certification path that best matches your skills and interests. There is no need to focus on one specific specialization.
How much hands-on customer or implementation experience is expected?
I could not find any information about a specific customer/implementation requirement in the official documents.

Re: Unable to Start Serverless Compute in Databricks Free Edition

Satyasai — Fri, 11 Sep 2026 05:38:26 GMT

Hi @HariSankar ,

If you opened an old notebook or imported a notebook (DBC, HTML, or Git), then Databricks may default its serverless execution environment version to an older version (like Version 1) that isn't supported anymore on the current Serverless Compute.

Fix: Open your notebook, go into the upper right corner where compute is attached, open Environment / Compute Settings, and update the Environment Version to the latest version (like Version 2 or higher). Or, you can copy-paste your code into a brand new notebook and attach Serverless Compute there.

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!

Re: Resolution of Missing Certificates in Accredible

Islam_hoti — Thu, 10 Sep 2026 10:28:58 GMT

Hi,

Sorry, that is a frustrating place to be stuck.

The thing that will unblock you fastest is separating the two problems. The account merge is one issue, but the panel discussion does not actually depend on it. Every Accredible credential has its own public verification link, and those work regardless of which account they sit under. Pull the links for each certificate from the original issuance emails and send them directly to whoever is coordinating the panel. That gets the scheduling moving while the account issue is still open.

On the merge itself, worth checking whether you can add the second email address to your Accredible profile rather than waiting on a deletion. If the credentials were issued to that address, linking it can surface them in one place without anyone having to merge anything.

For the ticket, reopen the original rather than filing a new one, and reference the previous ticket number so the history stays attached. New tickets tend to restart from zero. It is also worth posting in the Certifications board here, since Databricks staff monitor that one and have escalated credential issues before.

Good luck, and I hope the panel gets scheduled soon.

Re: DELETE Removed the Customer Record—but Did It Remove the Data?

Islam_hoti — Thu, 10 Sep 2026 10:19:06 GMT

Good breakdown, and the logical versus physical distinction is the part most teams get wrong. Three gaps worth adding to that runbook.

Change data feed. If it is enabled on the table, the deleted rows also exist in the _change_data directory as change records. Those are cleaned by VACUUM, but it is a second copy that people forget exists, so a table that looks clean after REORG and VACUUM can still have the record sitting in its change feed until retention passes.

Shallow clones. A shallow clone references the source data files rather than copying them, so a clone keeps deleted data reachable even after you have handled the source. It also runs the other way: running VACUUM on a source table that has shallow clones can leave those clones raising FileNotFoundException. Either way, clones need to be enumerated as part of the process, not discovered afterwards.

Log retention. delta.deletedFileRetentionDuration defaults to seven days and controls when VACUUM can remove data files, but delta.logRetentionDuration defaults to thirty days and governs the transaction log itself. The log carries per file column statistics, including minimum and maximum values, so for some columns the deleted values can persist in log metadata after the data files are gone. Worth checking whether that matters for the fields in question.

One operational note: on Unity Catalog managed tables, predictive optimization may already be running VACUUM on its own schedule. That is convenient but it means the timing is not yours, which matters if you need to evidence exactly when physical removal happened.

Databricks Support -0100505- Exam Suspended because non compliance requirements set by test sponsor

rxn95606 — Thu, 10 Sep 2026 09:17:57 GMT

@Cert-Team @Cert-TeamOPS

I am writing to urgently escalate my existing support case #01005055 regarding my Databricks certification exam being suspended due to an alleged non-compliance issue.

I raised the case promptly and have already followed up, but I have still not received a substantive response or resolution.

My exam was suspended despite my intention to comply with all examination requirements, and I am requesting that the case be reviewed by the appropriate Certification/Exam Operations team as soon as possible.

Could you please:

Confirm the current status of case ##0100505.
Escalate the case to the appropriate Certification/Exam Operations team.
Review the exam/session logs and circumstances surrounding the suspension.
Confirm whether my completed exam attempt can be reviewed/evaluated.
If the attempt cannot be evaluated, provide the earliest possible option to reschedule the examination without requiring me to purchase another attempt.

I would appreciate an urgent response as I have already been waiting beyond the normal support timeframe.

Please treat this as an escalation of my existing case rather than a new request.

Thank you for your assistance.

Kind regards,
Rahul

I had some problems with my badges too. I tried linking my company email as secondary email so I could access them, but it turned out my company was blocking Accredible emails as spam. After I linked my account successfully, I was able to see my badges.

Resolution of Missing Certificates in Accredible

ajaymittal — Thu, 10 Sep 2026 06:24:37 GMT

I have successfully completed all the required certifications and courses for the Databricks Champion Program. All the certificates and badges were issues but these certifications are not visible in my Accredible account associated with username@company.com.

I raised ticket requesting the deletion of the duplicate account and the merger of all certifications into my primary account (username@company.com). The ticket was closed but unfortunately the issue still persists and the team is unable to view all my certificates.

As a result, my discussion with the panel cannot be scheduled. Has anyone faced a similar situation? If so, how was it resolved?

Thank you!

Databricks AppQuest - Dev kit !

edward_wong — Thu, 10 Sep 2026 00:01:48 GMT

I pointed Claude Code at the repository to analyze the directory structure. It identified the YAML configuration file as the key starting point, since it lacked the connection details for the database, branches, and other environment-specific settings.

Once I populated those configuration values, I deployed the app successfully. I then located the newly created service principal role and granted it the necessary read/write permissions.

Are Unscored Questions Really Unscored?

Ariooo — Wed, 09 Sep 2026 23:37:10 GMT

I recently took two Databricks certification exams: Data Engineer Professional and, last night, Generative AI Engineer Associate.

For my first exam, I was very stressed because I had no previous Databricks certification and did not fully know what to expect.

The first 10 questions felt difficult, and I was already thinking:

"Maybe I should have taken the Associate exam first."

But later I found easier questions, increased my speed, reached the end, and used the remaining time to review marked questions. I kept fighting until the timer ended.

My second exam felt different.

Before the GenAI Associate exam, I was much more confident. But once it started, I saw many long scenario-based questions and immediately felt strong time pressure.

My exam had 56 questions in 90 minutes, while the official scored-question count is 45.

That means roughly 25% more questions with 0% more time.

This is why I believe unscored questions are not truly neutral.

They may not directly affect the score, but they still consume time, attention, and mental energy. Every minute spent on an unscored question is a minute that cannot be spent on a scored one.In the final minutes, I still had three questions to finish and had to answer them very quickly, partly based on educated guesses.

I understand that Databricks needs experimental questions to improve future exams, but I think the current approach creates a fairness issue. A better approach could be to make experimental questions optional, with proportional extra time and perhaps an incentive such as a future exam discount.

My main feedback is simple:

Unscored questions can still negatively affect a candidate’s scored performance when the total exam time stays fixed.

And one final lesson from both exams: never give up because the beginning feels difficult or because the clock is against you.

Fortunately, I passed the exams.

Reissue Voucher

aayush1907 — Wed, 09 Sep 2026 20:21:27 GMT

Hello Databricks Training Team,

I am writing to request assistance with reissuing a 50% certification voucher that I earned during the Databricks Advanced Learning Festival (June 15 – July 6, 2026).

I successfully completed my learning pathway and originally received the email containing my voucher code. However, the email was accidentally deleted from my inbox and trash folder, and I am unable to recover it. Because the voucher code does not display directly inside my Databricks Academy learning portal dashboard, I cannot access the code to book my exam.

Could your backend team please look up the specific promo code that was assigned to my account and resend it to me?
