Progressive Delay

The format of such a delay is retries:delay, where the number of retries is counted from the original rollback and the delay time is given in milliseconds. The maximum allowed delay is five seconds (5000 ms). The following example shows a string that specifies a delay of 1000 milliseconds following five failed retries. In other words, it specifies no delay for the first five attempts at redelivery, then a one-second delay for each subsequent attempt.

Example 1

5:1000

You can also cascade these delay actions to become progressively longer as the number of retries increases. Entries are separated by a semicolon followed by a space. The following example shows a string that specifies a one-second delay following five failed attempts at redelivery, ana a five second delay following a total of ten failed attempts.

Example 2

5:1000; 10:5000
