Hello, Can I enable Change Data Feed on Streaming Tables? How should I do this? I couldn't find this in the existing documentation https://learn.microsoft.com/en-us/azure/databricks/delta/delta-change-data-feed .
Hi, I've got a problem and I have run out of ideas as to what else I can try. Maybe you can help? I've got a delta table with hundreds millions of records on which I have to perform relatively expensive operations. I'd like to be able to process some...
Hi @Michał , One detail/feature to consider when working with Declarative Pipelines is that they manage and auto-tune configuration aspects, including rate limiting (maxBytesPerTrigger or maxFilesPerTrigger). Perhaps that's why you could not see this...
working in a Unity Catalog-enabled Databricks workspace, and we have several materialized views (MVs) that were created through a Delta Live Tables (DLT) / Lakeflow pipeline.Currently, the original owner of the pipeline has moved out of the project,...
Hi @Data_NXT ,You can change the owner of a materialized view if you are a both a metastore admin and a workspace admin.Use the following steps to change a materialized views owner:Open the materialized view in Catalog Explorer, then on the Overview ...
Hello, I have created data frame on csv file when I try to write it as:df_op_clean.write.format("delta").save("/Volumes/optimisation/trial")I get this error :Cannot access the UC Volume path from this location. Path was /Volumes/optimisation/trial/_d...
Also to add on this:avoid overlap between tables and Volumes.Create a separate folder for tables and files.Unity catalog does this too if you use managed tables/volumes.
Hi there !!! I would like to find the most suitable orchestration process to promote data between medallion layers I need to solve the following key architectural decision for scaling my multi-tenant data lake in Databricks.My setup:Independent medal...
Hey mbanxp! The most scalable and maintainable orchestration pattern for multi-tenant medallion architectures in Databricks is to build independent pipelines per table for all clients, with each pipeline parameterized by client/tenant. Why this appro...
Hi community,Is it possible for a workflow to reference multiple Git sources? Specifically, can different tasks within the same workflow point to different Git repositories or types of Git sources?Ty
A workflow can reference multiple Git sources. You can specify the git information for each task. However, I am not sure you can have multiple GitProvider for the same workspace....
Over the past few weeks, I’ve been exploring ways to capture streaming metrics from our data load jobs. The goal is to monitor job performance and behavior in real time, without disrupting our existing data load pipelines.Initial Exploration: Streami...
Hello, using the JDBC driver, when I retrieve the metadata of a ResultSet, the type for a TIMESTAMP_NTZ is not correct (it's a TIMESTAMP one).My SQL is a simple SELECT * on a table where you have a TIMESTAMP_NTZ columnThis works when retrieving metad...
Hello @EricCournarie! Just to confirm, were you initially using the JDBC driver v2.7.3? According to the release notes, this version adds support for the TIMESTAMP_NTZ data type.
Hi Team,While creating a Declarative ETL pipeline in Databricks, I tried to configure a notebook using the "Add existing assets" option by providing the notebook path. However, I received a warning message:"Legacy configuration detected. Use files in...

Hi Everyone,I am working on setting up success/failure notifications for a large number of jobs in our Databricks environment. The manual process of configuring email notification using UI for each job individually is not scalable and is becoming ver...
@Raj_DB Databricks sends notifications via its internal email service, which often requires the address to be a valid individual mailbox or a distribution list that accepts external mail. If your group email is a Microsoft 365, Please check if “Allow...
Hello, I'm trying to fill a STRUCT field with a PreparedStatement in Java by giving a JSON string in the PreparedStatement.But it complains Cannot resolve "infos" due to data type mismatch: cannot cast "STRING" to "STRUCT<AGE: BIGINT, NAME: STRING>"....
Could you provide a sample of JSON string along with a code you're using? Otherwise it will be hard for us to help you.
In all Databricks documentation, the examples use import dlt to create streaming tables and views. But, when generating sample Python code in ETL pipeline, the import in the sample is:import pyspark import pipelines as dpWhich one is the correct libr...
@yit Functionally, they are equivalent concepts (declarative definitions for streaming tables, materialized views, expectations, CDC, etc.). The differences you’ll notice are mostly naming/ergonomics:Module name:Databricks docs & most existing notebo...
