My company is having trouble connecting Databricks to Tableau Server. We need to be able to publish Hyper Files that are developed using Python on Databricks Notebooks to our Tableau Server, but it seems impossible to get a connection established des...
We are encountering a scenario where we need to enable support for Incremental Processing on Materialized views having DLT base tables. However, we have observed that the compute is being executed with the COMPLETE_RECOMPUTE mode instead of INCREMENT...
Moreover, we have CDF enabled DLT tables, but as per documentation we see a limitation if CDF is enabled then row Tracking won't be possible. Use row tracking for Delta tables | Databricks on AWSBut as per our use case we need incremental processing ...
I am using the Feature Engineering client when writing to a time series feature table. Then I have cried two data bricks jobs with the below code. I am running with different run_dates (e.g. '2016-01-07' and '2016-01-08'). When they run concurrently,...
@zed Clustering by your date column can indeed help avoid the ConcurrentAppendException without incurring the strict partitioning constraints that a “time series feature table” normally disallows. Unlike partitioning, CLUSTER BY does not create physi...
I'm currently testing materialized views and I need some help understanding the refresh behavior. Specifically, I want to know if my materialized view is querying the full table (performing a full refresh) or just doing an incremental refresh.From so...
To validate the status of your materialized view (MV) refresh, run a DESCRIBE EXTENDED command and check the row corresponding to the "last refresh status type."RECOMPUTE indicates a full load execution was completed.NO_OPERATION means no operation w...

Did any one tried to bring data using the newly announced Lakehouse federation and ingest using DELTA LIVE TABLES? I'm currently testing using Materialized Views. First loaded the full data and now loading last 3 days daily and recomputing using Mate...
Hi @NathanSundarara , regarding your current approach, here are the potential solutions and considerations- Deduplication: Implement deduplication strategies within your DLT pipeline. For example clicksDedupDf = ( spark.readStream.table("LIVE.rawCl...
Hey,I read the page about incremental refresh. Will you make it available on more than just serverless compute?If so, when?ThanksReference - https://docs.databricks.com/en/optimizations/incremental-refresh.html
Hi All,could you provide the best practices for building and optimizing DBT models in databricks.Regards,Phani
@Phani1 Please let us know if after going through @szymon_dybczak references, you still need some guidance on more specific aspects that we can help with.
Hi Community,How to read the CDF logs in materialized views created by DLT Pipeline?Thanks for you time,
@jeremy98 correct, If permissions management is complex, consider using standard Delta tables with CDF enabled and orchestrate changes through Databricks Workflows. This approach simplifies collaboration and avoids issues with restricted internal sch...
Hi there,My team is developing some SQL Dashboards. I would like to know how many people view that dashboard/or at least click to it and then queries triggered.I found out that there is one endpoint provided by Databricks: List Queries | Query Histor...
When I click to the dashboard, there are 6 statements in my dashboard -> I receive 6 records in `system.access.audit`.But the event_time is different, I expect event_time should be the same across records. So with the differences in event time, how c...
Hi All ,We have a use case where we need to connect AWS Databricks to a GCP storage bucket to access the data. In Databricks We're trying to use external locations and storage credentials, but it seems like AWS Databricks only supports AWS storage b...
Hi @Phani1 ,You can use delta sharing. In that way you can create share that will allow you to access data stored in GCS and it's govern by UC permissions model.What is Delta Sharing? | Databricks on AWSYou can also use legacy approach, but it doesn'...
Hi All,Regrading creating clusters in Databricks I'm getting quota error have tried to increase quotas in the region where the resource is hosted still unable to increase the limit, is there any workaround or could you help select the right cluster ...
Hi @svm_varma ,You can try to create Standard_DS3_v2 cluster. It has 4 cores and your current subscription limit for given region is 6 cores. The one you're trying to create needs 8 cores and hence you're getting quota exceeded exception.You can also...
I am experiencing performance issues when loading a table with 50 million rows into Delta Lake on AWS using Databricks. Despite successfully handling other larger tables, this especific table/process takes hours and doesn't finish. Here's the command...
Thank you for your question! To optimize your Delta Lake write process: Disable Overhead Options: Avoid overwriteSchema and mergeSchema unless necessary. Use: df.write.format("delta").mode("overwrite").save(sink) Increase Parallelism: Use repartition...
