We have the same issue using a shared cluster running DBR 14.3:Code executed: dfNew = dfTmp.withColumn(HashKeyColumnName, F.sha2(F.concat_ws("||", *ColumnList), 256))Error received: Error in callback <bound method UserNamespaceCommandHook.post_run_ce...
Due to the limitations with all output data needing to be stored in one target we have stopped using DLT until more flexibility is added. If anyone has a workaround we are open to suggestions.
Hi Zavi,One potential workaround is to establish multiple DLT pipelines, with each pipeline specifically configured to point to a unique target. This approach effectively allows for a diverse range of output data to be stored across various targets.T...
Hi , We are trying to load data from a delta table to a dataframe(a copy of original table) . Initially delta table has count 911 . The dataframe in which the data is loaded also has the same count .Now, we are deleting some records from the delta...
Hi, There is a way to retain the copy of data frame, even if the data in underling table is manipulated but that's a memory expensive operation, be careful while using it.df1 = spark.createDataFrame(df.rdd.map(lambda x: x), schema=df.schema)Here we a...
Hi,If I connect databricks (trial version) with AWS/Azure/Google Cloud and then work on dashboards and Genie - will there be any minimal charges, or its completely free to use the cloud services?

Hi Databricks Team,I would like to kindly request the addition of an offline option (Test centre Examination) for the Databricks certification.With the current technical issues that have been occurring, I am now hesitant and anxious about taking the ...
Using online proctor keeps the cost for exams lower, but we can look into this option.

Along with Job aborted due to stage failure: if you see slave lost... then it is due to less memory allocated for executors, more cores per executor more memory required or the other possibility is you have used max cpu available in cluster and the d...
For a data processing pipeline I use structured streaming and arbitrary stateful processing. I was wondering if the partitioning over several worker nodes and thus updating the state from different worker nodes has to be considered (e.g. using a lock...
Hi @fperry, When using applyInPandasWithState in PySpark, updates to each group’s state are automatically saved across invocations1. The function you provide should take parameters (key, Iterator[pandas.DataFrame], state) and return another Iterator[...
There is no distinction to make, it's VM's and you can't choose. Databricks SQL Serverless Warehouses uses K8s under the hood though.
Hello Community,Today I was in Tips and Tricks - Optimizations webinar and I started being confused, they said:"Don't partition tables <1TB in size and plan carefully when partitioning• Partitions should be >=1GB" Now my confusion is if this recommen...
that is partitions on disk.Defining the correct amount of partitions is not that easy. One would think that more partitions is better because you can process more data in parallel.And that is true if you only have to do local transformations (no shu...

Curious to hear how you guys optimize compute. As in how you dig into the details of the Spark execution and improve?
That is it. Usually, people take the time it takes to run a job/query/process as their KPI. Then you start to check which processes are taking more time, drilling down one by one. Sometimes it could be a misplaced .cache(), .collect() or display() t...

Hi @teaholic, The syntax for checkboxes in Markdown is correct: - [ ] for an unchecked box and - [x] for a checked box.Make sure there’s a space between the brackets and the hyphen, like this: - [x].
