Timeout for operation to complete.

The duration is a string in the form of AMOUNTunit where AMOUNT is an integer, and unit is one of the following:

  • ms: milliseconds

  • s: seconds

  • m: minutes

  • h: hours

Underscore (_) character is ignored in the AMOUNT. unit is optional and defaults to s if not specified.

The following are a few of the valid DURATIONs:

  • 5: 5 seconds

  • 5s: 5 seconds

  • 10000ms: 10000 milliseconds

  • 10_000_000ms: 10000000 milliseconds

This is a client-side timeout, the operation you started maybe in progress on the server-side even if the given timeout is exceeded.
