Prevent command concurrency #37

Open ptitFicus opened 3 years ago

ptitFicus commented 3 years ago

In some scenarios, commands should not be run concurrently.

There is several possible needs :

Command should not be run concurrently with other commands of the same type on the same id
Command should not be run concurrently with any other command on the same id

There is also several way to handle concurrent command :

Keep second command waiting until events generated by the first command are consumed
Reject second command
