[feature] Databricks Addon - upgrade to databricks/databricks provider and implement new features.

[nusrath432]

Upgrade the Databricks Addon: https://github.com/Azure/caf-terraform-landingzones/tree/main/caf_solution/add-ons/databricks_v1

• change the provider: from:

  source  = "databrickslabs/databricks"
  version = "~> 0.3.9"

  to:

  source  = "databricks/databricks"
  version = "~> 1.3.0"

Implement the following:

• AWS
• Compute
• Databricks SQL
• Log Delivery
• MLflow
• Security
• Storage
• Unity Catalog
• Workspace

@arnaudlh @LaurentLesle Do we add a new addon databricks_v2 or upgrade the existing one as it has only cluster implemented.

@nusrath432 Usually our criteria would be to create a databricks_v2 if we are unable to preserve a config created with 0.3.9 when we upgrade to 1.3.0. If you have some bandwidth for testing that might help understanding the the behavior! Thanks!

Hi @nusrath432 ,

Would like to check if including support for databbricks notebooks is under consideration. I have created an issue #420 for the same. https://github.com/Azure/caf-terraform-landingzones/issues/420

Including databricks notebook resource would help to automate the notebook deployment into the workspace.

Thanks, cc: @arnaudlh

@arnaudlh Thanks, I agree and yes, normally I would have just created databricks_v2 but since databricks_v1 has so little implemented, I felt we could upgrade itself. For now, I think databricks_v2 is good and you can take a decision at merge time when it is fully tested.

@RameshIlla: Yes, the intention is to implement in an iterative way so that all the resources supported by https://registry.terraform.io/providers/databricks/databricks/latest/docs are added (AWS exception). It has to be side hustle for me but I'll try to get the structure ready soon.

Meanwhile, you could delete #420 and track it in a single issue please.

Thanks @nusrath432 , I have marked #420 as closed so we can continue tracking here.

@arnaudlh @LaurentLesle How can we do the following from this addon: 1 - export the outputs attributes of the databricks_cluster to a keyvault as secrets - the keyvault could be remote landingzone or current landingzone I am aware that within the main CAF module, we could use a block like below:

dynamic_keyvault_secrets = {
  mykeyvault = {
    myattribute = {
      output_key    = "resource-type"
      resource_key  = "myresourcekey"
      secret_name   = "mysecretname"
      attribute_key = "myattribute"
    }
  }
}

but this only works within the CAF main module and for the current landingozne

• how can we use same design pattern within addons for remote keyvaults or new current landingzone keyvault.

Any input on the above use case is highly appreciated please.

@LaurentLesle Can you guide how the dynamic_keyvault_secrets are to be implemented in a add-on module, please.
