MemSQL

Learn how to add MemSQL as a resource in StrongDM.

MemSQL is now known as SingleStore. This documentation remains to assist users of legacy MemSQL datasources.

Overview

This guide describes how to add MemSQL as a datasource in StrongDM.

When the resource is added, StrongDM proxies client connections through a node (gateway, relay, or proxy cluster). This enables centralized access control, credential management, and audit logging. StrongDM supports standard MySQL-compatible clients and drivers that use the MemSQL/MySQL wire protocol.

Use this guide to complete all necessary preparations to add this resource to your StrongDM environment; input the correct properties in the Admin UI, CLI, SDKs, or Terraform provider; and test for a successful connection.

For general information about how to add a database as a resource in StrongDM, see our main guide, Add a Datasource.

Supported Versions and Clients

StrongDM supports MemSQL (SingleStore) clusters accessible over the standard MySQL wire protocol.

StrongDM is compatible with all MySQL-compatible MemS;QL clients, including:

• CLI tools such as mysql

• GUI clients like DBeaver, DataGrip, or MySQL Workbench

• Application libraries and drivers such as JDBC, ODBC, mysqlclient, or sqlalchemy

Prerequisites

To add your resource in StrongDM, you need to meet several technical and configuration prerequisites. Please ensure that the following requirements are met.

1In StrongDM, you must have the following: n

• Administrator permission level

• At least one operational StrongDM node (gateway, relay, or proxy cluster) that can reach the MemSQL host and port (default 3306)

• Valid database credentials (username and password) for the resource

• If using secrets management tools for storing your database credentials, a Secret Store configured in StrongDM

To verify that the resource is accessible by the node, log in to the gateway or relay and use Netcat: nc -zv <HOSTNAME> <PORT> (in this example, nc -zv testdb-01.fancy.org 3306). If your gateway server can connect to this hostname, proceed.

Netcat is a tool for checking various hostnames and ports by either sending data (a ping) or checking for listeners on the ports. The command in the aforementioned example use "-z" to check for listeners without sending data and "-v" to show verbose output. If you don't have Netcat, you can install the Netcat package with whatever package manager you are using, such as "apt-get install netcat".

On the MemSQL side, you must have the following:

• Database user with appropriate privileges (read-only for limited use, or CRUD/admin permissions for broader use)

• Authentication information, including hostname, port, database name, username, and password

• TLS/SSL enabled if required by your organization

• Network accessibility: ensure security groups, VPC settings, or firewall rules permit StrongDM nodes to connect

Resource Management in StrongDM

After all prerequisites and prep work is done, you are ready to add the resource to StrongDM. This section provides instructions for adding the resource in either the StrongDM Admin UI, CLI, Terraform provider, or SDKs.

Admin UI

Set up and Manage With the Admin UI

If using the Admin UI to add MemSQL as a resource to StrongDM, use the following steps.

1. Log in to the StrongDM Admin UI.

2. Go to Resources > Datasources.

3. Click Add datasource.

4. For Datasource Type, select MemSQL.

5. Complete all required configuration properties for your selected datasource type.

6. Click Create to save the resource.

7. Click the resource name to view status, diagnostic information, and setting details.

CLI

Set up and Manage With the CLI

This section provides an example of how to add the resource using the StrongDM CLI. For more information and examples, please see the CLI Reference documentation.

Configuration Properties

The following configuration properties are required to define a MemSQL datasource in StrongDM. These settings control how StrongDM connects to the database, authenticates the connection, and optionally uses encryption or secret management. Each property must be correctly configured to ensure connectivity and access enforcement through StrongDM.

Property	Requirement	Description
Display Name	Required	Meaningful name to display the resource throughout StrongDM; exclude special characters like quotes (") or angle brackets (< or >)
Datasource Type	Required	MemSQL
Proxy Cluster	Required	Defaults to "None (use gateways)"; if using proxy clusters, select the appropriate cluster to proxy traffic to this resource
Hostname	Required	Hostname for your database resource; must be accessible to a gateway or relay
Port	Required	Port to use when connecting to your resource; default port value is 3306
Connectivity Mode	Required	Select either Virtual Networking Mode, which lets users connect to the resource with a software-defined, IP-based network; or Loopback Mode, which allows users to connect to the resource using the local loopback adapter in their operating system; this field is shown if Virtual Networking Mode enabled for your organization
IP Address	Optional	If Virtual Networking Mode is the selected connectivity mode, an IP address value in the configured Virtual Networking Mode subnet in the organization network settings; if Loopback Mode is the selected connectivity mode, an IP address value in the configured Loopback IP range in the organization network settings (by default, 127.0.0.1); if not specified, an available IP address in the configured IP address space for the selected connectivity mode will be automatically assigned; this field is shown if Virtual Networking Mode and/or multi-loopback mode is enabled for your organization
Port Override	Optional	If Virtual Networking Mode is the selected connectivity mode, a port value between 1 and 65535 that is not already in use by another resource with the same IP address; if Loopback Mode is the selected connectivity mode, a port value between 1024 to 64999 that is not already in use by another resource with the same IP address; when left empty with Virtual Networking Mode, the system assigns the default port to this resource; when left empty for Loopback Mode, an available port that is not already in use by another resource is assigned; preferred port also can be modified later from the Port Overrides settings
DNS	Optional	If Virtual Networking Mode is the selected connectivity mode, a unique hostname alias for this resource; when set, causes the desktop app to display this resource's human-readable DNS name (for example, k8s.my-organization-name) instead of the bind address that includes IP address and port (for example, 100.64.100.100:5432)
Healthcheck Database	Required	Database name you would like to connect to specifically for healthchecks from StrongDM
Secret Store	Optional	Credential store location; defaults to Strong Vault; learn more about Secret Store options
Username	Required	Username to utilize when connecting to this datasource; displays when Secret Store integration is not configured for your organization or when StrongDM serves as the Secret Store type
Password	Required	Password for the user connecting to this datasource; displays when Secret Store integration is not configured for your organization or when StrongDM serves as the Secret Store type
Username (path)	Required	Path to the secret in your Secret Store location (for example, path/to/credential?key=optionalKeyName where key argument is optional); required when using a non-StrongDM Secret Store type
Password (path)	Required	Path to the secret in your Secret Store location (for example, path/to/credential?key=optionalKeyName where key argument is optional); required when using a non-StrongDM Secret Store type
Require Native Password Authentication	Optional	Enable if the resource requires the use of mysql_native_password for all connections; this option is available for backwards compatibility with prior MySQL versions
Use Azure Single Server Usernames	Optional	If selected, the hostname is appended to the username when interacting with a database.azure.com address
Resource Tags	Optional	Datasource Tags consisting of key-value pairs <KEY>=<VALUE> (for example, env=dev)

Secret Store options

By default, datasource credentials are stored in StrongDM. However, these credentials can also be saved in a secrets management tool.

Non-StrongDM options appear in the Secret Store dropdown if they are created under Network > Secret Stores. When you select another Secret Store type, its unique properties display. For more details, see Configure Secret Store Integrations.

Resource status

After a resource is created, the Admin UI displays that resource as unhealthy until the healthchecks run successfully. When the resource is ready, the Health icon indicates a positive, green status.

When the resource does not display a positive status, click the resource name to go to the Diagnostics tab and check for errors.

Test the Connection

After you have added your resource in StrongDM, follow these steps to verify that it’s working correctly.

1. Assign yourself access by ensuring that your user or role has access to the resource. In the StrongDM Admin UI, go to Access > Roles, and verify that the resource is attached to a role you’re in.

2. In the CLI, run sdm status to list the available datasources. Ensure that the resource appears in your list of accessible datasources.

3. Start a session to the resource, as in the following example:

   sdm connect ms-prod

4. Connect with a standard MySQL-compatible client. For example:

   mysql -h $MYSQL_HOST -P $MYSQL_PORT -u $MYSQL_USER -p$MYSQL_PASSWORD $MYSQL_DATABASE

5. Run a test query, such as:

   SELECT VERSION();

6. In the StrongDM Admin UI, check Logs > Queries (and Logs > Connections) to verify that activity was captured.

When these steps succeed, you’re ready to connect to your resource through StrongDM.
