---------------------------------------
Summary: Stop instantiating all classes on the first heartbeat
Key: MINIFICPP-1803
URL: https://issues.apache.org/jira/browse/MINIFICPP-1803
Project: Apache NiFi MiNiFi C++
Issue Type: Bug
Reporter: Marton Szasz
When producing the first heartbeat, BuildDescription::getClassDescriptions
instantiates *every single class* of each loader. In the case of AWS, the
processors happen to derive from S3Processor, and they contain a data member of
type Aws::Client::ClientConfiguration, whose default constructor makes HTTP
calls to AWS.
The easy fix is to delay the initialization of this particular member to
onSchedule.
The proper fix is to change the class loading and class description generation
logic to store more metadata about classes that are collected at registration
time, using compile-time introspection, instead of instantiating the classes
and using dynamic_cast.
This issue is about the proper fix. For the easy fix, see MINIFICPP-1802.
