TigerGraph

Connect your TigerGraph graph databases to Memex for AI-powered graph analytics.

What is TigerGraph?

TigerGraph is a native parallel graph database platform designed for advanced analytics and machine learning. It excels at handling complex, interconnected data and can traverse billions of relationships in real-time. TigerGraph is used for fraud detection, recommendation engines, supply chain analysis, and more. Once connected, Memex can explore your graphs, run queries, and help you analyze your connected data through natural conversation.

What You'll Need

Credential	Description	Example
Host	TigerGraph Cloud or server URL	https://myinstance.i.tgcloud.io/
Username	TigerGraph username	tigergraph
Password	TigerGraph password	Your secure password
Graph Name	Name of the graph to connect to	MyGraph

Finding Your Credentials

For TigerGraph Cloud

1. Log in to TigerGraph Cloud

2. Navigate to your cluster/instance

3. Find your connection details in the cluster overview:

   • Host: Your instance URL (e.g., https://myinstance.i.tgcloud.io/)

   • Username: The username you created during setup (default is often tigergraph)

   • Graph Name: The name of the graph you want to query

Step 1: Access TigerGraph Cloud Console

Log in to TigerGraph Cloud and select your instance.

Step 2: Get Instance URL

Copy your instance URL from the dashboard. It typically looks like: https://your-instance-name.i.tgcloud.io/

Step 3: Get Graph Name

1. Open GraphStudio from your instance

2. In the top-left dropdown, you'll see your available graphs

3. Note the name of the graph you want to connect

Step 4: Verify User Credentials

Use the username and password you set up when creating your TigerGraph Cloud instance. If you need to create a new user, use GraphStudio's Admin Portal.

For Self-Hosted TigerGraph

Contact your database administrator to obtain:

• The TigerGraph server URL

• A username and password with appropriate permissions

• The name of the graph you need to access

Connecting to Memex

1. Open the Memex Hub from the sidebar

2. Click on the Connectors tab

3. Find and click the TigerGraph card

4. Enter your Host URL, Username, Password, and Graph Name

5. Give your connection a memorable name (e.g., "Fraud Detection Graph")

6. Click Add Connection

Verifying Your Connection

Once connected, try asking Memex:

What vertex types are in my TigerGraph?

You should see a list of vertex types in your graph.

Using Your Connection

Here are some examples of what you can ask:

List all edge types and their connections in my graph

How many vertices of each type are in my graph?

Security Considerations

Authentication

TigerGraph uses username/password authentication:

• Use strong, unique passwords

• Create dedicated users for Memex with appropriate permissions

• Avoid using the default tigergraph superuser for applications

User Permissions

TigerGraph supports role-based access control. Best practices:

• Create a dedicated user for Memex

• Grant read-only permissions on the graphs needed

• Use the Admin Portal in GraphStudio to manage users and roles

Network Security

For TigerGraph Cloud:

• Connections are encrypted with HTTPS

• Configure IP allowlisting if available

• Use private endpoints for sensitive workloads

For self-hosted TigerGraph:

• Enable HTTPS for encrypted connections

• Configure firewall rules to restrict access

• Use SSL/TLS certificates

Never share your TigerGraph credentials. For production use, create dedicated service accounts with minimal required permissions.

Troubleshooting

Connection Failed

• Verify the Host URL is correct and includes https://

• Ensure the TigerGraph instance is running

• Check if your IP address is allowed to connect

• Verify the instance URL is accessible from your network

Authentication Failed

• Double-check your username and password

• Ensure the user exists and is active

• Verify the password hasn't expired

• Check if the user has permission to access the specified graph

Graph Not Found

• Verify the graph name is spelled correctly (case-sensitive)

• Ensure the graph exists on the instance

• Check that the user has permission to access the graph

• In GraphStudio, verify the graph is visible in the graph dropdown

Query Errors

• Ensure the graph has data (vertices and edges)

• Verify the schema is properly defined

• Check if installed queries are required for certain operations

• Review TigerGraph logs for detailed error messages

Timeout Issues

• Large graph traversals may take time—be patient or add limits

• Check the instance resource utilization

• Consider optimizing your graph schema or adding indexes
