Do we have general guidance around how other customers manage Dev and Prod environments in Databricks? Is it recommended to have separate workspaces for them? What are the pros and cons of using the same workspace with folder or repo level isolation?
I'm trying to run Delta Lake MergeMERGE INTO source USING updates ON source.d = updates.sessionId WHEN MATCHED THEN UPDATE * WHEN NOT MATCHED THEN INSERT *I'm getting an SQL errorParseException: mismatched input 'MERGE' expecting {'(', 'SELECT', 'FR...
The merge SQL support is added in Delta Lake 0.7.0. You also need to upgrade your Apache Spark to 3.0.0 and enable the integration with Apache Spark DataSourceV2 and C
There's a lot of different ML formats out there and I am confused about how they should be fitting together. How should I be thinking about MLflow and MLeap working together?
I am trying to set up a demo with a really simple spark ML model and i see this error repeated over and over in the logs in the serving UI:/databricks/chauffeur/model-runner/lib/python3.6/site-packages/urllib3/connectionpool.py:1020: InsecureRequestW...
Not sure how the containers for each model version work on the endpoints, but looks like Model serving endpoints use a 7.x runtime. So those would be Spark 3.0, not Spark 3.1
I can see an example on how to call the vacuum function for a Delta lake in python here. how to use the same in python %sql VACUUM delta.`dbfs:/mnt/<myfolder>` DRY RUN
The dry run for non-SQL code is not yet available in Delta version 0.8. I see there is a bug that is opened with delta opensource in git . hope it get resolved soon
I have run a few MLflow experiments and I can see them in the experiment history, but none of the metrics have been logged along with them. I thought this was supposed to be automatically included. Any idea why they wouldn't be showing up?
Hi Want to find the storage bucket where all my runs' logs are stored , I want to do analytics on logs , can you please help me knowing which bucket or path I should look for
The root bucket where are not directly accessible outside databricks so you need to read the logs from databricks notebook only
I'm trying to create a new experiment on mlflow but I have this problem:Exception: Run with UUID l142ae5a7cf04a40902ae9ed7326093c is already active. snippet mlflow.set_experiment("New experiment 2") mlflow.set_tracking_uri('http://mlflow:5000') ...
You have to run mlflow.end_run() to finish the first experiment. Then you can create another

The impact will be only on the files touched by the MERGE operation. The newly created files will not be optimized and data co-locality is not ensured. However, the files which are not touched by the MERGE operation will continue to show the improvem...

Hyperopt offers hp.uniform and hp.loguniform, both of which produce real values in a min/max range. hp.loguniform is more suitable when one might choose a geometric series of values to try (0.001, 0.01, 0.1) rather than arithmetic (0.1, 0.2, 0.3). Wh...
aws s3 ls --summarize --human-readable --recursive s3://root-bucket-name/Bucket owner could run this command or get the info from console. Would that work ?
