You can configure both per-user usage limits and server-wide defaults.

Server Defaults

To configure the default rate limits applied to all users, click Settings -> Server. The following options can be configured on this page:

• Max. Requests Per Hour: Enter the default maximum requests allowed per hour per user. A value of 0 allows unlimited requests per hour by default.
• Max. Concurrent Requests: Enter the default maximum simultaneous requests allowed per user. A value of 0 allows unlimited simultaneous requests by default.

User-Specific Limits

To configure rate limits for an individual user, click Settings -> Users, select a user, and click Edit. The following options can be configured in the resulting dialog:

• Privileges: Select the HTTP methods the user is allowed to access, GET, POST, PUT/PATCH/MERGE, or DELETE. These correspond to SELECT, INSERT, UPDATE, and DELETE statements, respectively.
• Max. Requests (hr): Enter the maximum requests allowed for this user per hour. A value of 0 allows the user unlimited requests per hour.
• Max. Concurrent: Enter the maximum simultaneous requests allowed for this user. A value of 0 allows the user unlimited simultaneous requests. User-specific rate limits override the server defaults. An empty value for one of the user settings will use the server default.
