Class OpTestDelay

source code

Sleeps for a configured amount of time.

This is used just for debugging and testing.

Parameters:

duration: the time to sleep, in seconds
on_master: if true, sleep on the master
on_nodes: list of nodes in which to sleep

If the on_master parameter is true, it will execute a sleep on the master (before any node sleep).

If the on_nodes list is not empty, it will sleep on those nodes (after the sleep on the master, if that is enabled).

As an additional feature, the case of duration < 0 will be reported as an execution error, so this opcode can be used as a failure generator. The case of duration == 0 will not be treated specially.
