💾 Storage Configuration

Default Storage (DBFS)

Databricks File System (DBFS) is automatically provisioned with every workspace.

# Access DBFS
dbutils.fs.ls("dbfs:/")

# Upload file to DBFS
dbutils.fs.cp("file:/tmp/data.csv", "dbfs:/FileStore/data.csv")

# List files
display(dbutils.fs.ls("dbfs:/FileStore/"))

⚠️ Warning: DBFS is ephemeral and tied to workspace lifecycle. Use external storage for production data.

External Storage - Azure Data Lake Storage Gen2

Create Storage Account

# Create storage account
az storage account create \
  --name sadatabricksprod \
  --resource-group $RESOURCE_GROUP \
  --location $LOCATION \
  --sku Standard_LRS \
  --kind StorageV2 \
  --enable-hierarchical-namespace true

# Create container
az storage container create \
  --name data \
  --account-name sadatabricksprod \
  --auth-mode login

Mount Storage to Databricks

Option 1: Service Principal Authentication (Recommended)

# Create service principal
configs = {
  "fs.azure.account.auth.type": "OAuth",
  "fs.azure.account.oauth.provider.type": "org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider",
  "fs.azure.account.oauth2.client.id": "<application-id>",
  "fs.azure.account.oauth2.client.secret": dbutils.secrets.get(scope="<scope-name>", key="<secret-key>"),
  "fs.azure.account.oauth2.client.endpoint": "https://login.microsoftonline.com/<tenant-id>/oauth2/token"
}

# Mount storage
dbutils.fs.mount(
  source = "abfss://data@sadatabricksprod.dfs.core.windows.net/",
  mount_point = "/mnt/data",
  extra_configs = configs
)

# Verify mount
display(dbutils.fs.ls("/mnt/data"))

Option 2: Unity Catalog External Locations (Recommended for Unity Catalog)

-- Create storage credential
CREATE STORAGE CREDENTIAL azure_storage_credential
WITH (
  AZURE_SERVICE_PRINCIPAL = 'application-id',
  AZURE_CLIENT_SECRET = 'client-secret',
  AZURE_TENANT_ID = 'tenant-id'
);

-- Create external location
CREATE EXTERNAL LOCATION data_lake
URL 'abfss://data@sadatabricksprod.dfs.core.windows.net/'
WITH (STORAGE CREDENTIAL azure_storage_credential);

-- Grant access
GRANT CREATE TABLE ON EXTERNAL LOCATION data_lake TO `data_engineers`;

# Create Key Vault
az keyvault create \
  --name kv-databricks-prod \
  --resource-group $RESOURCE_GROUP \
  --location $LOCATION \
  --enable-soft-delete true \
  --enable-purge-protection true

# Add secret
az keyvault secret set \
  --vault-name kv-databricks-prod \
  --name storage-account-key \
  --value "your-storage-account-key"

Configure Databricks Secret Scope

# Create secret scope backed by Key Vault
# Note: This is done via UI at https://<databricks-instance>#secrets/createScope

# Use secret in notebook
storage_key = dbutils.secrets.get(scope="key-vault-scope", key="storage-account-key")

spark.conf.set(
  "fs.azure.account.key.sadatabricksprod.dfs.core.windows.net",
  storage_key
)

Enable Audit Logging

# Create Log Analytics workspace
az monitor log-analytics workspace create \
  --resource-group $RESOURCE_GROUP \
  --workspace-name law-databricks

# Get workspace ID
LA_WORKSPACE_ID=$(az monitor log-analytics workspace show \
  --resource-group $RESOURCE_GROUP \
  --workspace-name law-databricks \
  --query id -o tsv)

# Configure diagnostic settings
az monitor diagnostic-settings create \
  --name databricks-audit-logs \
  --resource $WORKSPACE_ID \
  --workspace $LA_WORKSPACE_ID \
  --logs '[{"category": "dbfs","enabled": true},{"category": "clusters","enabled": true},{"category": "accounts","enabled": true},{"category": "jobs","enabled": true},{"category": "notebook","enabled": true},{"category": "ssh","enabled": true},{"category": "workspace","enabled": true}]'

-- Grant schema permissions
GRANT USAGE ON SCHEMA analytics TO `data_engineers`;

-- Row-level security
CREATE ROW FILTER region_filter ON sales_data
FOR SELECT
WHEN user() = 'regional_manager@company.com'
THEN region = 'EMEA';

Cluster Policies

Enforce organizational standards with cluster policies.

{
  "cluster_type": {
    "type": "fixed",
    "value": "all-purpose"
  },
  "spark_version": {
    "type": "regex",
    "pattern": "13\\.3\\..*-scala2\\.12"
  },

    cluster_size="2X-Small",
    min_num_clusters=1,
    max_num_clusters=3,
    auto_stop_mins=20
)

# Get connection details
print(f"Server Hostname: {warehouse.jdbc_url}")
print(f"HTTP Path: {warehouse.http_path}")

Connect from Power BI: 1. Get Data → Azure → Azure Databricks 2. Enter Server Hostname and HTTP Path 3. Authenticate with Azure AD 4. Select tables and load

Azure Data Factory Integration

{
  "name": "DatabricksLinkedService",
  "type": "Microsoft.DataFactory/factories/linkedservices",
  "properties": {
    "type": "AzureDatabricks",
    "typeProperties": {
      "domain": "https://adb-123456789.12.azuredatabricks.net",
      "authentication": "MSI",
      "workspaceResourceId": "/subscriptions/{subscription}/resourceGroups/{rg}/providers/Microsoft.Databricks/workspaces/{workspace}",
      "existingClusterId": "{cluster-id}"
    }
  }
}

✅ Best Practices

Resource Naming Conventions

Workspace: dbx-{environment}-{region}-{workload}
Clusters: clstr-{purpose}-{size}
Notebooks: nb-{project}-{function}
Jobs: job-{frequency}-{workload}

Examples:
  - dbx-prod-eastus-analytics
  - clstr-etl-large
  - nb-sales-processing
  - job-daily-revenue-calc

Cost Management

# Set cluster auto-termination
spark.conf.set("spark.databricks.cluster.autoTermination.minutes", "30")

# Use spot instances for dev
{
  "azure_attributes": {
    "spot_bid_max_price": -1,
    "first_on_demand": 1,
    "availability": "SPOT_WITH_FALLBACK_AZURE"
  }
}

# Monitor costs
%sql
SELECT
  usage_date,
  SUM(usage_quantity * list_price) as daily_cost
FROM system.billing.usage
WHERE usage_date >= CURRENT_DATE - 30
GROUP BY usage_date
ORDER BY usage_date DESC

Security Hardening

  1. Enable Private Link for all workspaces
  2. Use Unity Catalog for centralized governance
  3. Rotate secrets regularly via Key Vault
  4. Enable audit logging for compliance
  5. Implement RBAC at all levels
  6. Use service principals for automation
  7. Encrypt data with customer-managed keys

🆘 Troubleshooting

Common Setup Issues

Issue: Workspace creation fails with VNet injection

# Solution: Verify subnet delegation
az network vnet subnet update \
  --resource-group $RESOURCE_GROUP \
  --vnet-name vnet-databricks \
  --name snet-databricks-public \
  --delegations Microsoft.Databricks/workspaces

Issue: Cannot access workspace after creation

# Solution: Add firewall rule
az databricks workspace update \
  --resource-group $RESOURCE_GROUP \
  --name $WORKSPACE_NAME \
  --public-network-access Enabled

Issue: Cluster fails to start

# Check cluster logs
cluster_id = "0123-456789-abc123"
logs = w.clusters.get(cluster_id=cluster_id)
print(logs.state_message)

Diagnostic Queries

-- Check audit logs
SELECT timestamp, action_name, user_identity, response
FROM system.access.audit
WHERE action_name LIKE '%CLUSTER%'
ORDER BY timestamp DESC
LIMIT 100;

-- Monitor cluster utilization
SELECT
  cluster_id,
  AVG(cpu_utilization) as avg_cpu,
  AVG(memory_utilization) as avg_memory
FROM system.compute.clusters
WHERE timestamp >= CURRENT_TIMESTAMP - INTERVAL 1 DAY
GROUP BY cluster_id;

🎯 Next Steps

  1. Configure Unity Catalog - Set up centralized governance
  2. Create Delta Live Tables Pipeline - Build ETL workflows
  3. Set Up MLflow - Enable ML lifecycle management
  4. Implement Security - Harden your deployment
