Hi everyone,I’m looking to migrate ML model experiments from a source Databricks workspace to a target workspace. Specifically, I want to use Python and the available REST APIs for this process.Can anyone help me on this!Thanks in advance!
You can use https://github.com/mlflow/mlflow-export-import utility. The example given below doesn't use Python but uses CLI and CICD pipeline to do the same. https://medium.com/@gchandra/databricks-copy-ml-models-across-unity-catalog-metastores-188...
Hi, I'm super new to Databricks. I'm trying to do a little API scripting against my company's DB instance.I have this supersimple python (ver 3) which is meant to run a remote host. The script tries to a simple SQL query against my Databricks instan...
@gchandra Yes! This is the documentation I was seeking! Thank you so much
Hey guys, I have been using Postman for quite some time now and getting disappointed recently and want to make a swtich. Is there something better than Postman? I've heard about that APIDog is much easier to use with a much better UI, and support all...
Hi All,We are facing a situation where our data source is Snowflake, and the data is saved in a storage location(adls) in parquet format. However, the tables or data lack a date column or any incremental column for performing incremental loads to Dat...
Ideally you would have some change tracking system (cdc f.e.) on the source tables (Streams in the case of Snowflake, Introduction to Streams | Snowflake Documentation).But that is not the case.So I think you approach is ok. You cannot track what is...
I'm setting up a job in the Databricks Workflow UI and I want to pass a dynamic parameter, like the current date (run_date), each time the job runs.In Azure Data Factory, I can use expressions like @utcnow() to calculate this at runtime. However, I w...
As szymon mentioned, dynamic parameter values exist, but the functionality is still far from what Data Factory has to offer.I am pretty sure though that this will be extended.So for the moment I suggest you do the value derivation in data factory, an...
Hello,Would anyone know if it is possible to create a delta table using Python that includes a column that is generated by default as identity (identity column for which the value inserted can be manually overriden)?There seems to be a way to create ...
Hi @oleprince ,As far as I know, it's not possible yet to create tables with Identity columns using pyspark (DeltaTable api). You can create generated columns, but Identity columns are not allowed.The only way to achieve this is through Spark Sql.
Hey, I am new to Databricks, and I am trying to test the mlops-stack bundle. Within that bundle there is a feature-engineering workflow and I have a problem to make it run. The main problem is the following.the bundle specified the target to be $bund...
Scaling XGBoost and LightGBM models to handle exceptionally large datasets—those comprising billions to tens of billions of rows—presents a formidable computational challenge, particularly when constrained by the limitations of in-memory processing o...
Well, that's a superb article! Thank you for this great information, you write very well which I like very much. I am really impressed by your post. run 3
Hi All,We have a situation where we are collecting data from different Oracle instances.The customer is using Oracle GoldenGate to replicate this data into a storage location.From there, we can use Auto Loader or Delta Live Tables to read Avro files ...
Hi @Phani1 ,In my opinion this is really good setup. You have push scenario where Oracle GoldenGate is responsible for delivering data into storage, so you don't have to bother about extraction part. And autoloader is the best choice when it comes t...
Hi All,How can we connect Databricks Delta Lake to Essbase in OCI? We know that Essbase supports JDBC/ODBC. Is it possible to use Python or PySpark to read from Delta Lake and load the data into Essbase? I think using JDBC/ODBC might affect performan...
Hi All,We are establishing a connection from Denodo to Databricks. During the development phase, we utilized a personal access token associated with developer account. However, this approach is not considered a best practice for production environm...
I'm trying to create a delta live table from a Google PubSub stream.Unfortunately I'm getting the following error:org.apache.spark.sql.streaming.StreamingQueryException: [PS_FETCH_RETRY_EXCEPTION] Task in pubsub fetch stage cannot be retried. Partiti...
Hi @Retired_mod, it was indeed a permissions issue. Nevertheless, I must admit that the error message is slightly misleading.Thanks.
Hi community,Assume I generate a personal access token for an entity. Post generation, can I restrict the access of the entity to specific REST APIs? In other words, consider this example where once I use generate the token and setup a bearer token b...
@Surajv You have to rely on access control settings on resources and entities (users or service principals or create some cluster policies), rather than directly restricting the API endpoints at the token level.Note: API access based on fine-grained ...
