2.0.4

September 19, 2018

Compatibility

Software Version

Mule

4.0.0 and later

Anypoint Studio

7.0.0 and later

New Features

This release of Anypoint MQ Connector implements retry logic with exponential backoff.

Fixed Issues

  • Improves logger precision to avoid issues during transaction tracing.

  • Allows Subscriber prefetch to be disabled for predictability on API calls (see Known Issues).

Known Issues

Using prefetch can result in the loss of predictability of API calls. If prefetch is used, Anypoint MQ Connector aggressively tries to fetch messages, which results in increased API calls. If predictability and control on API requests is important, use the following steps to disable prefetch and strictly follow the polling time.

Only disable prefetch if predictability on API calls is more important than performance. Maximum possible performance is only available when prefetch is enabled.

To disable prefetch:

  1. Access a new or existing connector configuration of the MQ Subscriber component.

  2. Navigate to the Prefetch tab.

  3. Specify a Fetch size of 0. This disables prefetch.

  4. In the Studio General tab, specify a Polling time in milliseconds.

    This time interval is strictly adhered to when making API calls. Polling time defaults to 10 seconds if an explicit configuration is not present.

    If there are no messages in the queue, each poll that a subscriber makes waits for the duration of exactly half of the Polling time specified in the General tab. Polling time has a maximum value of 20000 milliseconds.

Note: Versions 2.0.2 - 2.0.3 were internal releases only without changes to the user interface or product usage.
