Summary: Rework script engine management in ExecuteScript processor
Key: MINIFICPP-1706
URL: https://issues.apache.org/jira/browse/MINIFICPP-1706
Project: Apache NiFi MiNiFi C++
Issue Type: Improvement
Reporter: Gábor Gyimesi
In [MINIFICPP-1222|https://issues.apache.org/jira/browse/MINIFICPP-1222] an
issue was raised that the script engines were not handled correctly by allowing
more engines in the queue than the maximum number of concurrent operations in
the ExecutePythonProcessor processor. This issue is also present in the
ExecuteScript processor.
In the ExecutePythonProcessor processor the queue was eventually removed in
https://github.com/apache/nifi-minifi-cpp/pull/1227 due the python's GIL not
allowing real concurrency. In the ExecuteScript processor we should have a
solution that allows concurrency with LUA engines limiting the number of
engines to the maximum concurrent operations limit, but having a single engine
for Python script executions.
