Information in this post Speed Up Data Flow: Databricks and SAS | Databricks Blog led me to using spark-sas7dbat package to read SAS files and save to delta for downstream processes with great results. I was able to load very large files quickly that...
Hi, i'm trying to run the notebooks but it doesn't do any activity.I had to create a cluster in order to start my code.pressing the play button inside of notebook does nothing at all.and the 'compute' , pressing play there on the clusters gives the e...
This is very common issue I see with community edition. I suppose the only work around is to create new cluster each time. More info on stackoverflow:https://stackoverflow.com/questions/69072694/databricks-community-edition-cluster-wont-start
Due to dependencies, if one of our cells errors then we want the notebook to stop executing.We've noticed some odd behaviour when executing notebooks depending on if "Run all cells in this notebook" is selected from the header versus "Run All Below"....
Has this been implemented? I have created a job using notebook. My notebook has 6 cells and if the code in first cell fails it should not run the rest of the cells
I'm seeking validation from experts regarding the data quality and consistency checks we're implementing as part of a data migration using Spark and Databricks.Our migration involves transferring data from Azure Data Lake to a different data lake. As...
Hi @Coders, I'd also consider some profiling checks for column stats and distribution just to be sure everything is consistent after the migration.Afterwards, you should consider the best-practice of implementing some data quality validations on the ...
We are trying to build data quality process for initial file level or data ingestion level for bronze and add more specific business times for silver and business related aggregates for golden layer.
Hi @laksh!You could take a look at Rudol Data Quality, it has native Databricks integration and covers both basic an advanced data quality checks. Basic checks can be configured by non-technical roles using a no-code interface, but there's also the o...
Hi Databricks Team, would like to implement data quality rules in Databricks, apart from DLT do we have any standard approach to perform/ apply data quality rules on bronze layer before further proceeding to silver and gold layer.

Hello, I made a delta live table workflow that created 3 streaming tables in unity catalog. I then removed the source code for the 3rd table from the workflow and reran. After about a week, the 3rd streaming table is no longer available in unity cata...
This makes sense @raphaelblg! Just to confirm my understanding, is the following statement true:If I remove the source code for a unity catalog DLT streaming table from a DLT pipeline and wait 7 days, that table will be dropped from unity catalog, an...
Hello I have a table that has a column defined as an identity (BIGINT GENERATED ALWAYS AS IDENTITY)I will be inserting rows into this table in parallelHow can I get the identity and use that within a pipelineParallel is relevant as there will be mult...
Hi @dpc ,What you're trying to achieve does not make sense in the context of identity columns. Look at below entry from documentation. So, the answer is - if you want to have concurrent transaction, don't use identity columns Declaring an identity co...
I am currently using the `apply_changes` feature. I saw for the regular decorator `dlt.table` you can create temporary tables. I do not see the option you could use this feature with `dlt.create_streaming_table(`, in the sql version it looks it is su...

We are currently working on Databricks DLT tables to transform data from bronze to silver. we are specifically instructed us not to use mount paths for accessing data from ADLS Gen 2. To comply, I configured storage credentials and created an externa...
Hi @yvishal519 ,Since you're using hive metastore you have no other option than mount points. Storage credentials and external locations are only supported in Unity Catalog
When I list the available schemas I get the following:{"schemas":[{"schema":"storage","state":"AVAILABLE"},{"schema":"operational_data","state":"UNAVAILABLE"},{"schema":"access","state":"AVAILABLE"},{"schema":"billing","state":"ENABLE_COMPLETED"},{"s...
I have the same issue for the compute schema. Workspace is UC enabled and I'm account admin.
If I am using Databricks Runtime 11.3 and above to create managed Delta tables cataloged in Unity Catalog (Databricks’ data catalog), I don’t need to worry about optimizing the underlying file sizes or configuring a target file size for my Delta tabl...
Hi @Amit_Dass_Chmp ,Yep, according to documentation. As of second question, such capability will be available in the future. If you are using Databricks Runtime 11.3 and above to create managed Delta tables cataloged in Unity Catalog (Databricks’ dat...
