Rate limits

note

If you use the rate limit feature and have feedback to share, contact us.
You must enable this feature in the application properties file to use it.

Data Migrator allows you to manage resources by limiting the number of calls Hive Migrator can make simultaneously in your environment.

How it works​

You can specify the number of requests that can be made within a time period for a specific agent, or all agents configured for a product instance.

  1. Open /etc/wandisco/hivemigrator/application.properties in a text editor.
  2. Add the following feature parameter line:
    preview.feature.ratelimit=ON
  3. Save the file.
  4. Restart the Hive Migrator service. See System service commands - Hive Migrator.
