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

Dear Databricks Community Team,I am writing to request assistance regarding a badge display issue on my profile.I received an email notification confirming that I earned the DAIS24 Attendee badge for the Data & AI Summit 2024. However, when I check m...
DELETE Removed the Customer Record—but Did It Remove the Data?A successful Delta Lake DELETE makes a record disappear from the current table version. However, it may not immediately remove that record from the underlying storage files.Imagine a ficti...
Nice writeup — this distinction between logical and physical deletion is exactly the kind of thing that trips people up when a "right to erasure" request lands on your desk and legal wants a straight yes/no answer. Worth flagging that all of this sof...
I've been exploring the Databricks ecosystem and recently started looking more closely at Databricks Apps and Lakebase.What I find interesting is how Databricks is moving beyond data processing and analytics into application development.Lakebase prov...
Hi Everyone,I am Soumitra Dutta,I have an issue with LLM API and Retrieval-Augmented Generation (RAG). Sometimes the same query returns different answers even if the retrieved documents and the prompt are the same.The retrieval results are useful, bu...
Hi Soumitra,Yes, this is a common issue with RAG systems. Even with the same context and prompt, LLMs can sometimes generate different responses.A few things I would check:Keep temperature low (0–0.2) for more consistent results.Make the prompt clear...
Dear Databricks Team,I hope you are doing well.I am writing to follow up regarding the 50% certification voucher associated with the Databricks Learning Festival held from 15 June to 6 July.I successfully completed the courses under the Data Analyst ...
Hello @TyreseR19, Could you please ensure that both required courses for the Data Analyst learning path were fully completed during the Learning Festival event window? Please verify that every component of each course is marked as completed, includin...
Hello fellow techies,For the past few days I have been doing some R&D wrt Lakeflow connect. I came to the understanding that, Lakeflow Ingestion Pipeline and SQL server connection have a 1:1 mapping. This would mean that as number of servers scales n...
Most modern enterprise data platforms favor managed ingestion (Lakeflow Connect) for standard relational databases like SQL Server. The operational complexity of monitoring 50 managed pipelines is significantly lower than maintaining custom CDC code,...
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 mus...
Hi @SantiNath_Dey, Databricks has solid building blocks for this, and there's even a purpose-built metadata framework you can lean on. At its core, your pipeline needs to do three things...generate surrogate keys at each level, resolve parent referen...
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 distributio...
This is a great use case for a data reconciliation framework. Automating schema, row counts, aggregates, and row-level hash comparisons would save a lot of manual effort and make migration validation much more reliable.
I'm excited to share that I recently cleared the Databricks Certified Context Engineer Associate certification.What I found most interesting while preparing was how Context Engineering goes beyond prompt engineering. It made me think more deeply abou...
I’m noticing some unusual inconsistencies in how scripts execute on databricks.com compared to when the same workflow is triggered through a mobile-based API. On Databricks, the script runs perfectly when executed directly inside a cluster notebook. ...
This kind of difference can be surprisingly easy to miss because the same notebook may behave differently depending on how it is launched. In Databricks, compute type, runtime, permissions, parameters, and whether the execution is interactive or a jo...
