+
+# Data Source: azurerm_kusto_database
+
+Use this data source to access information about an existing Kusto Database
+
+## Example Usage
+
+```hcl
+data "azurerm_kusto_database" "example" {
+  name                = "my-kusto-database"
+  resource_group_name = "test_resource_group"
+  cluster_name        = "test_cluster"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of the Kusto Database.
+
+* `resource_group_name` - (Required) The Resource Group where the Kusto Database exists.
+
+* `cluster_name` - (Required) The name of the Kusto Cluster this database is added to.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The Kusto Cluster ID.
+
+* `location` - The Azure Region in which the managed Kusto Database exists.
+
+* `hot_cache_period` - The time the data that should be kept in cache for fast queries as ISO 8601 timespan.
+
+* `soft_delete_period` - The time the data should be kept before it stops being accessible to queries as ISO 8601 timespan.
+
+* `size` - The size of the database in bytes.
+
+## Timeouts
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/docs/configuration/resources.html#timeouts) for certain actions:
+
+* `read` - (Defaults to 5 minutes) Used when retrieving the Kusto Database.
