I am unable to see the lakeflow designer option in my databricks account. Even the previews option is not there ... Please let me know how can access that
Hi team,When using table update or file arrival trigger, what latency I can expect for the trigger. Does Databricks poll the source by some schedule? If yes, whether the poll is free?Thanks
Hi @Ashwin_DSA ,Thanks for the input. This is very helpful. For the last question, we thought about to create another table as staging, which is specifically used as trigger. Any time source has changes, we will update the staging table too. However ...
Hello Community!I am writing to you with my idea about data ingestion job which we have to implement in our project.The data which we have are in CSV file format and depending on the case it differs a little bit. Before uploading we pivoting csv file...
Hi @maikel, You don't have to build a custom solution for this. Databricks now has native components that align very well with what you want. If you want the job to start as soon as new files land in a volume, the recommended approach is to use file-...
Hi,What the maximum size to read using dbutils.fs.head()?is there a limit? because AI says 10MB and I couldn't find useful info in documentations, while I tried in the actual one and it was only limited by the driver memory.Thanks in advance.
dbutils.fs.head() itself does not have a documented hard cap like 10 MB. From the official dbutils reference, the signature is: dbutils.fs.head(file: String, max_bytes: int = 65536): String “Returns up to the specified maximum number of bytes in t...
This is a small deficiency, but a fix would be nice to have.For a long time now, the Sample Data previewer in the Unity Catalog explorer has been unable to show tables that contain a certain kind of column. Instead of showing sample rows of the tabl...
Yes, my vector space is commonly of dimension 4000 or 8000.I don't write any dense vectors to table; can't speak to what happens previewing that type.Thanks for taking up the issue!
Hi,On a managed Delta table I get:SELECT * FROM abc VERSION AS OF 25;Error:DELTA_UNSUPPORTED_TIME_TRAVEL_BEYOND_DELETED_FILE_RETENTION_DURATION Cannot time travel beyond delta.deletedFileRetentionDuration (168 HOURS).Audit logs show VACUUM START/END...
VACUUM will never delete files on the latest version even if Version 10 was not accessed or modified as it represents the current state of the table. VACUUM targets files that are not referenced by the recent version. It identifies files that were re...

Hi @Muralidharan_A, To your question about whether retry_on_failure does more than a manual refresh, the answer is yes! retry_on_failure (along with pipelines.numUpdateRetryAttempts and pipelines.maxFlowRetryAttempts) performs classified, timed retri...
Hello,I'm looking for the best option to retrieve between 1-1.5TB of data per day from a REST API into Databricks.Thank you,Rodrigo Escamilla
Hi @RodrigoE, It would be helpful to have additional information to recommend the best options for your scenario. Who owns the REST API?Is that in your control? Can the source push data to Databricks, or should you pull on a schedule? If the source ...
Hi. I'm testing out the "Run parameters" you see in Jobs & Pipelines. As far as I know, this value is set manually by "Job parameters" on the right side bar. Can I set the value within code though? Like if I want something dynamically generated depen...
Hi @397973, Interesting question and I did not know the answer. So, I ran the test you described on my own workspace. Sharing what I found in case it saves you time. The short answer is that the task values won't populate the Run parameters column. V...
I have a batch job that runs thousands of Deep Clone commands, it uses a ForEach task to run multiple Deep Clones in parallel. It was taking a very long time and I realized that the Driver was the main culprit since it was using up all of its memory ...
You’re seeing (a monotonic / stair‑step climb in driver RAM over thousands of DEEP CLONE statements) is a very common pattern when the driver is not “holding data”, but holding metadata, query artifacts, and per‑command state that accumulates faster ...
Dear Experts,I have a requirement to implement PostgreSQL CDC using Databricks Lakeflow Connect. While setting up the tables, I am unable to see the list of available tables, even though the connection settings appear to be correct.Could you please s...
Hi @harisrinivasay, @szymon_dybczak is correct. You must enter the database name. Lakeflow Connect can only connect to and query that database, and list the schemas and tables if you provide the correct name. If the name is incorrect or if you don’t ...
We have set up Change Tracking on multiple SQL Servers for Lakeflow Connect successfully in the past, but lately we are having lots of problems with a couple of servers. The latest utility script has been run and both lakeflowSetupChangeTracking and ...
Thanks @Ashwin_DSA , @amirabedhiafi for your swift responses.I had high hopes when I saw lakeflowUtilityVersion_1_5() is queried, as I found the database user for the ingestion gateway connection (i.e. the @User parameter for both dbo.lakeflowSetupCh...
