-----------------------------------------
Assignee: Ferenc Gerlits
> 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
> Affects Versions: 0.6.0, 0.9.0, 0.7.0, 0.10.0, 0.11.0
> Reporter: Marton Szasz
> Assignee: Ferenc Gerlits
> Priority: Major
> Labels: MiNiFi-CPP-Hygiene
>
> 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.
