Hi, I am using Unity Catalog as storage for data. I have an external system that establishes connection to Unity Catalog via a JDBC connection using the Databricks driver:Configure the Databricks ODBC and JDBC drivers - Azure Databricks | Microsoft L...
Hi,Thanks in advance.I am new in DLT, the scenario is i need to read the data from cloud storage(ADLS) and load it into my bronze table. and read it from bronz table -> do some DQ checks and load the cleaned data into my silver table. finally populat...
Hi @alj_a, In Delta Live Tables (DLT), the database or schema name is specified in the table name itself. You can specify the database name in the @dlt.table decorator by using the format database_name.table_name.
I am using the databricks VSCode extension to sync my local repository to Databricks Workspaces. I have everything configured such that smaller syncs work fine, but a full sync of my repository leads to the following error:Sync Error: Post "https://<...

I am running a relatively simple SQL query that writes back to a table on a Databricks serverless SQL warehouse, and I'm trying to understand why there is a "Columnar To Row" node in the query profile that is consuming the vast majority of the time s...
@dave_d We do not have a document with list of operations that would bring up ColumnarToRow node. This node provides a common executor to translate an RDD of ColumnarBatch into an RDD of InternalRow. This is inserted whenever such a transition is de...
Is there anyway to accomplish this ? I have an existing Delta Table and a separate Delta Live Table pipelines and I would like to merge data from a DLT to my existing Delta Table. Is this doable or completely impossible ?
Merging data from a Delta Live Table (DLT) into an existing Delta Table is possible with careful planning. Transition data from DLT to Delta Table through batch processing, data transformation, and ETL processes, ensuring schema compatibility.
Is there a way to use Compute Policies to force Delta Live Tables to use specific Databricks Runtime and PySpark versions? While trying to leverage some of the functions in PySpark 3.5.0, I don't seem to be able to get Delta Live Tables to use Databr...
BLOCK_OFFSET_INSIDE_BLOCK ROW_OFFSET_INSIDE_BLOCK command is not working in spark, but these command is running in hive , when running in spark it get failed with invalid column like that
i created one function using jar file which is present in the cluster location, but when executing the hive query it is showing error as no handler for udf/udaf/udtf . this queries is running fine in hd insight clusters but when running in databricks...
Hi @databicky ,
The error message "No handler for UDF/UDAF/UDTF" typically occurs when Spark cannot locate the UDF/UDAF/UDTF you registered. This can happen if the JAR file containing the UDF/UDAF/UDTF is not correctly loaded into Spark or the func...
Hi @BST, When running a Spark job in cluster mode, it involves a central manager (e.g., YARN, Mesos, Kubernetes), a driver program, and worker nodes. The driver program is submitted to the central manager, which allocates resources and decides where ...
I am baffled by the behaviour of Databricks:Below you can see the contents of the directory using dbutils in Databricks. It shows the `test.xlsx` file clearly in directory (and I can even open it using `dbutils.fs.head`) But when I go to use panda.re...
Hey, I encountered it recently. I can see you are using the shared cluster, try switching to a single user cluster and it will fix it.Can someone let me know why it wasn't working w a shared cluster?Thanks.
Hi There I am hoping for some guidance I have some 850 tables that I need to ingest using a DLT Pipeline. When I do this my event log shows that driver node dies becomes unresponsive likely due to GC.Can DLT be used to ingest large number of tablesI...
Delta Live Tables (DLT) can indeed be used to ingest a large number of tables. However, if you're experiencing issues with the driver node becoming unresponsive due to garbage collection (GC), it might be a sign that the resources allocated to the dr...
Hi team,When we reading the CSV file from azure blob using databricks we are not getting any key error and able to read the data from blob .But if we are trying to read XML file it failed with key issue invalid configuration . Error:Failure to inti...
OverviewTo update our Data Warehouse tables, we have tried two methods: "CREATE OR REPLACE" and "MERGE". With every query we've tried, "MERGE" is slower.My question is this: Has anyone successfully gotten a "MERGE" to perform faster than a "CREATE OR...
Hi @Graham Can you please try Low Shuffle Merge [LSM] and see if it helps? LSM is a new MERGE algorithm that aims to maintain the existing data organization (including z-order clustering) for unmodified data, while simultaneously improving performan...
