I have this delta lake in ADLS to sink data through spark structured streaming. We usually append new data from our data source to our delta lake, but there are some cases when we find errors in the data that we need to reprocess everything. So what ...

Hi @Manish P​ , You have three options for converting a Parquet table to a Delta table.Convert files to Delta Lake format and then create a Delta table:CONVERT TO DELTA parquet.`/data-pipeline/` CREATE TABLE events USING DELTA LOCATION '/data-pipelin...

I want to run aggregations on large windows (90 days) with small slide duration (5 minutes).Straightforward solution leads to giant state around hundreds of gigabytes, which doesn't look acceptable.Is there any best practices doing this?Now I conside...
Hi @Sergey Volkov​, Thanks for your question. Here are some fantastic articles on EWMA and Event-time Aggregation in Apache Spark™’s Structured Streaming. Please have a look. Let us know if that helps.https://towardsdatascience.com/time-series-from-s...
HI,Is there any way to disable launch workspace option in Azure portal for ADB.We have user accesses at resource group, so we need to restrict users who are part of owner or contributor role to launch ADB worksapce as admin.Thank you
Deny Assignments don't block subscription contributor to launch workspace and become admin. Actually I haven't find any way to block that after many tries of different methods.
Hello, Today on our workspace we access everything via mount points, we plan to change it to "abfss://" because of security, governance and performance reasons. The problem is sometimes we interact with files using "python only" code, and apparently ...

Hello,We have some Scala code which is compiled and published to an Azure DevOps Artifacts feed.The issue is we're trying to now add this JAR to a Databricks job (through Terraform) to automate the creation.To do this I'm trying to authenticate using...
As of right now, Databricks can't use non-public Maven repositories as resolving of the maven coordinates happens in the control plane. That's different from the R & Python libraries. As workaround you may try to install libraries via init script or ...
If you have a job that repeatedly run into Out-of-memory error (OOM) either on the driver or executors, automatically capture the heap dump on OOM event will help debugging the memory issue and identify the cause of the error.Spark config:spark.execu...
Is it necessary to use exactly that HeapDumpPath? I find I'm unable to get driver heap dumps with a different path but otherwise the same configuration. I'm using spark_version 10.4.x-cpu-ml-scala2.12.
We are adapting the multi-tasks workflow example from dbx documentation for our pipelines https://dbx.readthedocs.io/en/latest/examples/python_multitask_deployment_example.html. As a part of configuration we specify cluster configuration and provide ...
Tasks within the same multi task job can reuse the clusters. A shared job cluster allows multiple tasks in the same job to use the cluster. The cluster is created and started when the first task using the cluster starts and terminates after the last ...

Hey there Community!! I have a client that will produce a CSV file daily that needs to be moved from Bronze -> Silver. Unfortunately, this source file will always be a full set of data....not incremental. I was thinking of using AutoLoader/cloudFil...
I "up voted'" all of @werners suggestions b/c they are all very valid ways of addressing my need (the true power/flexibility of the Databricks UDAP!!!). However, turns out I'm going to end up getting incremental data afterall :). So now the flow wi...
