Identify and delete empty Vector Search endpoints

This page describes how you can identify and delete empty Vector Search endpoints. Because Vector Search endpoints are workspace-specific resources, you need to repeat this process for each workspace separately.

Requirements

• Databricks SDK for Python (databricks-sdk).
• Databricks Vector Search Python SDK (databricks-vectorsearch).
• Authentication configured (OAuth, PAT, or configuration profiles).
• CAN_MANAGE permission for Vector Search endpoints in target workspaces.

To install the required SDKs in your Databricks notebook or local Python environment:

# In a Databricks notebook
%pip install databricks-sdk databricks-vectorsearch

# In local Python environment
# pip install databricks-sdk databricks-vectorsearch

Identify empty endpoints

In the Databricks UI, vector search endpoints are shown on the Vector Search tab of the Compute screen. Toggle the Empty endpoints checkbox to display endpoints that have no indexes associated with them. Empty endpoints are also marked with a warning triangle icon as shown.

Authentication

This section describes authentication options.

Option 1. Run inside a Databricks notebook

When you run the code in a Databricks workspace notebook, authentication is automatic:

from databricks.vector_search.client import VectorSearchClient

# Credentials are picked up automatically from notebook context
client = VectorSearchClient()

Option 2. Personal access token (PAT)

For external environments, provide explicit credentials:

from databricks.vector_search.client import VectorSearchClient

client = VectorSearchClient(
    workspace_url="https://<your-instance>.cloud.databricks.com",
    personal_access_token="dapiXXXXXXXXXXXXXXXXXXXXXXXX"
)

Option 3. Use configuration profiles (Recommended for multiple workspaces)

Create a .databrickscfg file in your home directory and include a profile for each workspace:

[DEFAULT]
host = https://workspace1.cloud.databricks.com
token = dapiXXXXXXXXXXXXXXXXXXXXXXXX

[PRODUCTION]
host = https://workspace2.cloud.databricks.com
token = dapiYYYYYYYYYYYYYYYYYYYYYYYY

[DEVELOPMENT]
host = https://workspace3.cloud.databricks.com
token = dapiZZZZZZZZZZZZZZZZZZZZZZZZ

If you prefer not to use configuration profiles, you can specify credentials directly:

# Define workspaces with explicit credentials
workspace_configs = [
    {
        'workspace_url': 'https://workspace1.cloud.databricks.com',
        'token': 'dapiXXXXXXXXXXXXXXXXXXXXXXXX'
    },
    {
        'workspace_url': 'https://workspace2.cloud.databricks.com',
        'token': 'dapiYYYYYYYYYYYYYYYYYYYYYYYY'
    }
]

# Run cleanup, set `dry_run=False` to perform actual deletion
results = cleanup_multiple_workspaces(workspace_configs, dry_run=True)

Delete endpoints in a single workspace

Vector Search endpoints are workspace-specific. Here is a basic script to find and delete empty endpoints in a single workspace. To clean up empty endpoints across multiple workspaces, see Delete endpoints across multiple workspaces.

from databricks.vector_search.client import VectorSearchClient

def cleanup_empty_endpoints(client, dry_run=True):
    """
    Find and delete empty Vector Search endpoints.

    Args:
        client: VectorSearchClient instance
        dry_run: If True, only print what would be deleted without actually deleting

    Returns:
        List of deleted endpoint names
    """
    deleted_endpoints = []

    # List all Vector Search endpoints
    endpoints = client.list_endpoints()

    for endpoint in endpoints["endpoints"]:
        # List indexes in this endpoint
        indexes = list(client.list_indexes(name=endpoint["name"])['vector_indexes'])

        if len(indexes) == 0:
            if dry_run:
                print(f"[DRY RUN] Would delete empty endpoint: '{endpoint["name"]}'")
            else:
                print(f"Deleting empty endpoint: '{endpoint["name"]}'")
                try:
                    client.delete_endpoint(endpoint["name"])
                    deleted_endpoints.append(endpoint["name"])
                    print(f"✓ Successfully deleted: {endpoint["name"]}")
                except Exception as e:
                    print(f"✗ Failed to delete {endpoint["name"]}: {str(e)}")
        else:
            print(f"Endpoint '{endpoint["name"]}' has {len(indexes)} indexes - keeping")

    return deleted_endpoints

# Example usage
client = VectorSearchClient()  # Uses default authentication
# Set `dry_run=False` when you are ready to delete endpoints
deleted = cleanup_empty_endpoints(client, dry_run=True)
print(f"\nTotal endpoints deleted: {len(deleted)}")

Delete endpoints across multiple workspaces

To clean up empty endpoints across multiple workspaces, iterate through your configuration profiles:

from databricks.sdk import WorkspaceClient
from databricks.vector_search.client import VectorSearchClient
import logging

# Configure logging
logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')
logger = logging.getLogger(__name__)

def cleanup_workspace(profile_name=None, workspace_url=None, token=None, dry_run=True):
    """

    Args:

    """
    try:

            workspace_url = w.config.host
            client = VectorSearchClient(

        else:
            # Use default authentication (notebook context)
            client = VectorSearchClient()
            logger.info("Connected using default authentication")

        # Perform cleanup
        deleted = cleanup_empty_endpoints(client, dry_run=dry_run)

        return {

Custom filtering

You can add custom logic to exclude certain endpoints from deletion, as shown:

def should_delete_endpoint(endpoint, indexes):
    """
    Custom logic to determine if an endpoint should be deleted.

    Args:
        endpoint: Endpoint object
        indexes: List of indexes in the endpoint

    if len(indexes) > 0:
        return False

    # Don't delete endpoints with specific naming patterns
    protected_patterns = ['prod-', 'critical-', 'do-not-delete']
    for pattern in protected_patterns:
        if pattern in endpoint.name.lower():
            logger.warning(f"Skipping protected endpoint: {endpoint.name}")
            return False

    # Add more custom logic as needed
    return True

Export results

To save cleanup results to a file for auditing:

import json
from datetime import datetime

def export_results(results, filename=None):
    """Export cleanup results to JSON file."""
    if not filename:
        timestamp = datetime.now().strftime('%Y%m%d_%H%M%S')
        filename = f'vector_search_cleanup_{timestamp}.json'

    with open(filename, 'w') as f:
        json.dump({
            'timestamp': datetime.now().isoformat(),
            'results': results
        }, f, indent=2)

    logger.info(f"Results exported to: {filename}")

Troubleshooting

Authentication issues

• Verify that your PAT tokens are valid and not expired.
• Ensure configuration profiles are correctly formatted.
• Check that your tokens have the necessary permissions.

Permission errors

Verify that your user or service principal has CAN_MANAGE permission for Vector Search endpoints.

Network issues

For environments with proxy requirements, configure the SDK appropriately:

import os
os.environ['HTTPS_PROXY'] = 'http://your-proxy:po

Next steps

• Schedule this script to run periodically using Lakeflow Jobs.
• Integrate with your infrastructure-as-code pipeline.
• Add email or Slack notifications for cleanup summaries.
• Create a dashboard to track endpoint usage across workspaces.
