Execution Supervisor¶
Purpose¶
The execution supervisor in V1 is essentially the engine counterpart
to the Erlang or Elixir spawn-command
(for a process waiting for ExecuteTransaction-commands).
This will be more complicated in future versions
where a single transaction might be processed
by geo-distributed executors to allow for collocation with shards.
SpawnExecutor¶
- from Worker
Purpose¶
Informs the supervisor about the need to spawn a new Executor.
