Databricks Community

Hi @mouni2, Based on your description, your original account was likely a Databricks Community Edition account. Community Edition was retired on January 1, 2026, and existing Community Edition workspaces are no longer accessible. This is the most com...

Hi @gokkul, There are a few different patterns here depending on which direction you need data to flow. Let me break them down. READING DELTA/UC DATA FROM LAKEBASE (UC to Postgres) Synced tables are the primary mechanism for this. They automatically ...

Hi @spjti, Incorrect manager mappings in an employee hierarchy typically come from a few common root causes. Since the question is fairly open-ended, here is a checklist of the most likely issues and how to diagnose them in Databricks. COMMON REASONS...

Hi @chris84, You already identified the root cause: the JSON file was pretty-printed across multiple lines. By default, Spark's JSON reader expects one JSON record per line (sometimes called "JSON Lines" or NDJSON format). When it encounters a pretty...

Hi @Smriti2, The error "TIME TRAVEL is not allowed. Operation not supported on Streaming Tables" when the table is not intentionally a streaming table typically points to the table having pipeline-related metadata attached to it in the prod workspace...

Hi @Schusmeicer, The "Can not move tables across arclight catalogs" error you are seeing is specific to how Unity Catalog is managed on the Databricks Free Edition. "Arclight" is the internal infrastructure name for the Free Edition's managed Unity C...

Hi @crami, The "Cannot merge columns 'ColumnX' into 'ColumnX'" error you are seeing is caused by passing "delta.enableChangeDataFeed" as a write option on the DataFrame writer. Change Data Feed (CDF) is a table-level property, not a per-write option....

Hi @fehrin1, This is expected behavior on the Databricks Free Edition. The Free Edition documentation confirms that "outbound internet access is restricted to a limited set of trusted domains." https://docs.databricks.com/aws/en/getting-started/free-...

Hi @ruicarvalho_de, The behavior you are seeing is related to how the _metadata virtual column interacts with Spark Connect (which Serverless compute uses under the hood) and how deferred analysis changes when that hidden column is resolved. Here is ...

Hi @aranjan99, To add some detail to the earlier reply: the confusion here comes from the fact that the REST API and the Databricks CLI handle the "limit" parameter differently. REST API BEHAVIOR In the REST API (POST or GET to /api/2.1/jobs/runs/lis...

Hi @ShyamalaT, As @Advika and @szymon_dybczak mentioned, the hands-on labs that accompany Databricks Academy courses do require either an Instructor-Led Training (ILT) enrollment or a Databricks Academy Labs subscription. Here is a quick summary of y...

Hi @CuriousEngineer, This is a common scenario, and there are good solutions. Nice job including the code and the minimal reproducible example -- that makes it much easier to help. There are two places in your query that are very likely introducing d...

Hi @Kirankumarbs, Thanks for posting this. I can see from the thread that the existing replies confirmed the limitation but did not offer much in the way of alternatives. Let me provide a fuller picture. THE SHORT ANSWER You cannot set a custom max_r...
