Terraform provider to create cassandra tables - azure

Question

I'm looking to create cassandra DB tables through terraform, on Azure. I already have the relative keyspaces in place.
My deployment is leveraging azurerm, however their provisioner is lacking a cassandra-tables resources.
As of now, I can only deploy cassandra tables through Azure UI on the portal or with Azure CLI scripting, however this isn't the best solution for a variety of reasons.
Is there a provider that could help me with this? I'm giving a look around but it seems that there isn't much I could leverage.

Answer 1

For whatever reason it looks like hashicorp never implemented cassandra table in their provider. Their source code is missing the implementation for it.
I suggest filing a new bug on their repo. You can do that here

Answer 2

Apparently a workaround could be deploying the resource to Azure as ARM using the ARM provider in an "incremental" mode.
resource "azurerm_resource_group_template_deployment" "example" {
depends_on = [module.cassandratest]
name = "example-cassandra-tables"
resource_group_name = azurerm_resource_group.test.name
deployment_mode = "Incremental"
template_content = templatefile("resources/templatecosmos.json", {
cosmos_db_account_name = "test-cassandra-2",
keyspace_name = "keyspace1",
table_name = "test-table-2",
autoscale_max_throughput = 4000
})
}
CosmosDB Cassandra templates are documented here. An example of the contents of resources/templatecosmos.json:
