Adam Hunyadi updated MINIFICPP-1222:
------------------------------------
Description:
*Background:*
The ExecutePythonProcessor is expected to have a limit on the maximal number of
concurrent tasks it can run. This
{{{color:#403294}{{max_concurrent_tasks}}{color}}} number is currently handled
incorrectly, and the processor is able to run any number of tasks at the same
time, but only {{{color:#403294}{{max_concurrent_tasks}}{color}}} script-engine
is reused.
*Proposal*:
We should use {{{color:#403294}{{max_concurrent_tasks}}{color}}} as the size of
script-engine pool for the processor and always use engines from this pool,
wait otherwise.
