if file is renamed with file_name.sv.gz (lower case extension) is working fine, if file_name.sv.GZ (upper case extension) the data is read as corrupted, means it simply reading compressed file as is.
Recently I restarted look at a solution for this issue, I found out we can add few exception for allowing "GZ" in hadoop library as GzipCodec is invoked from there.
Hello Databricks Community,I am trying to connect databricks with datadog and have added datadog agent script in global init but it did not worked. Just to make sure if init script is working or not I have added below two lined of code in global init...
Thanks Slash for the reply. That seems to be a reason. I was following https://docs.datadoghq.com/integrations/databricks/?tab=driveronly and missed that configuration.
Databricks now supports the VARIANT data type, which works well in the UI and within Spark environments. However, when working with SQLAlchemy, the VARIANT type doesn't seem to be fully implemented in the latest databricks-sql-connector[sqlalchemy]. ...
This is actually an open source project. By looking at the code, it seems that VARIANT is not yet supported. Depending on your knowledge of the code base, you could create an own PR. Or just open an issue there, and wait for the support of the devs.
Hello,I've recently noticed we've never been using Analyze Table, after doing z-ordering / liquid clustering investigations and noticing the query plans for our delta tables were not considering these paths.I'm trying to execute the following command...
Hi @RobCox, This might be due to incorrect configuration settings or insufficient permissions. Ensure that the fs.azure.account.key configuration is accurate and that the service principal or identity running the command has the necessary permissions...
Whenever I run my script it resets the notebook state:"The spark driver has stopped unexpectedly and is restarting. Your notebook will be automatically reattached.at com.databricks.spark.chauffeur.Chauffeur.onDriverStateChange(Chauffeur.scala:1467)"T...
I have a requirement where I need to ingest large xml files and flatten the data before saving it as parquet files. I have created a python function to flatten the complex types (array & struct) from the ingested xml dataframe. I'm using the spark-xm...
Hi @reachrishav ,Since 14.3 there is a native support for read and write XML files. Maybe check if it works faster than the library that you've used:Read and write XML files | Databricks on AWSAnd you've mentioned that you write python function to fl...
Hello,I'm creating a DLT pipeline where I read a Kafka stream, perform transformations using UDFs, and save the data in multiple tables. When I define the functions directly in the same notebook, the code works fine. However, if I move the code into ...
Hi @YS1 ,Have you added the python file in the Pipeline settings, in the list of source code?
A delta live table pipeline reads a delta table on databricks. Is it possible to limit the size of microbatch during data transformation?I am thinking about a solution used by spark structured streaming that enables control of batch size using:.optio...
One other thought -- if you are considering using pandas_udf api, there is a way to control batch size there:pandas_udf guide note the comments there about arrow batch size params.
In databricks I can set a config variable at session level, but it is not found in the context variables:spark.conf.set(f"dataset.bookstore", '123') #dataset_bookstore spark.conf.get(f"dataset.bookstore")#123 scf = spark.sparkContext.getConf() allc =...
A while back I think I found a way to get python to list all the config values. I was not able to re-create it. Just make one of your notebook code sections scala (first line) and use the second line: %scala(spark.conf.getAll).foreach(println)
I found this old post (https://community.databricks.com/t5/data-engineering/databricks-cluster-web-terminal-different-permissions-with-tmux/td-p/26461) that was never really answered.I am having the same problem. If I am in the raw terminal, I can a...
Hi @Twilight, To resolve this, ensure the `tmux` session runs under the same user context as the raw terminal, verify environment variables are set correctly, initialize `tmux` with the same shell and environment settings, check for any ACLs on the `...
If I have a table which is clustered by (a, b, c) and I issue a query filtering on (b, c), will the query benefit from the optimization by the cluster of (a, b, c)?
Hi @oripsk, When you query a table clustered by columns (a, b, c) and filter on (b, c), the query will not fully benefit from the clustering optimization. Clustering works best when the query filter includes the leading column(s) in the clustering or...
On newer Databricks Runtime versions, %conda commands are not supported. You can use %pip commands instead:%pip list I have tested this on Databricks Runtime 15.4 LTS Beta.
Hello,I have tables created on unity catalog that point to the raw area , from these tables I need to create a data model (facts and dimensions) that will aggregate this data, transform certain things. Then I need to store in the Azure Datalake in de...
Hi @ad_k, To create a data model from Unity Catalog tables and store it in Azure data lake in Delta format, use Databricks Notebooks with PySpark or SQL. The process involves reading raw data from Unity Catalog, transforming it into fact and dimensio...
