What is the use If I am able to upload and not able to read. I have only read access on the cluster
Depends on what you're looking for from a management perspective, but one option is the Account API which allows deploying/updating/configuring multiple workspaces in a given E2 accountUse this API to programmatically deploy, update, and delete works...

Databricks must have access to at least two subnets for each workspace, with each subnet in a different availability zone per docs here
This is designed for optimal user experience and as a capacity planning strategy where if instances are not available in one AZ, the other subnet in a different AZ can be used to deploy instance from instead

They seem to have similar functions. What is the recommended pattern here?
mlflow.<model-type>.log_model(model, ...) saves the model to the MLflow tracking server. mlflow.<model-type>.save_model(model, modelpath) saved the model locally to a DBFS path.More details at https://docs.databricks.com/applications/mlflow/models...
We are having difficulties running our jobs with spot instances that get re-claimed by AWS during shuffles. Do we have any documentation / best-practices around this? We went through this article but is there anything else to keep in mind?
Due to the recent changes in AWS spot market place , legacy techniques like higher spot bid price (>100%) are ineffective to retain the acquired spot node and the instances can be lost in 2 minutes notice causing workloads to fail.To mitigate this, w...
No, each table must be defined once. You can Use UNION If you need to combine multiple inputs to create a table. Adding or removing UNION from an incremental table is a breaking operation that requires a full-refresh.
I created several tables in my DLT pipeline but didn't specify a location to save them on creation. The pipleline seems to have ran, but I don't know where the tables actually are. How can I find them?
Checkout the configuration storage under settings . If you didn't specify the storage setting, the system will default to a location in dbfs:/pipelines/
Yes, in your write stream you can save it as a table in the delta format without a problem. In DBR 8, the default table format is delta. See this code, please note that the "..." is supplied to show that additional options may be required: df.writeSt...
When using SQL, I can use the Create Live Table command and the Create Incremental Live Table command to set the run type I want the table to use. But I don't seem to have that same syntax for python. How can I set this table type while using Python?
The documentation at https://docs.databricks.com/data-engineering/delta-live-tables/delta-live-tables-user-guide.html#mixing-complete-tables-and-incremental-tables has an example the first two functions load data incrementally and the last one loads...
By default, only 10 MB of data can be broadcasted. spark.sql.autoBroadcastJoinThreshold can be increased up to 8GBThere is an upper limit in terms of records as well. We can't broadcast more than 512m records. So its either 512m records or 8GB which...
After creating my Delta Live Table and running it once, I notice that the maintenance job that was created along with it continues to run at the scheduled time. I have not made any updated to the DLT, so the maintenance job theoretically shouldn't ha...
You could change the table properties of the associated tables to disable automatic scheduled optimizations. More details at https://docs.databricks.com/data-engineering/delta-live-tables/delta-live-tables-language-ref.html#table-properties
