Manage quotas in Aiven for Apache Kafka®

Manage quotas in your Aiven for Apache Kafka® service to control network throughput and CPU usage per client.

Prerequisites

• An Aiven for Apache Kafka® service.
• Access to the Aiven Console or an authenticated Aiven CLI.

2. Click Quotas in the sidebar.

3. Click Add quota.

4. Enter the Client ID or User.

5. Set one or more quota values:

   • Consumer throttle: Maximum data rate for consumers, in bytes per second.
   • Producer throttle: Maximum data rate for producers, in bytes per second.
   • CPU throttle: Maximum CPU usage for the client, as a percentage.
   note

   Enter default to apply the quota to all clients or users.

6. Click Add.

Aiven CLI

Use avn service quota create with at least one of --client-id or --user, and at least one quota parameter.

Example: Set a 1 MiB/s producer and consumer throttle for user alice:

avn service quota create kafka-doc \
  --user alice \
  --consumer-byte-rate 1048576 \
  --producer-byte-rate 1048576

Example: Set a default quota for all users:

avn service quota create kafka-doc \
  --user default \
  --consumer-byte-rate 5242880

  -d '{
    "user": "alice",
    "consumer_byte_rate": 1048576,
