-------------------------------------------
Summary: Resolver parallelism can fail on kubernetes as the
resolverParallelism is not accurate
Key: KARAF-7074
URL: https://issues.apache.org/jira/browse/KARAF-7074
Project: Karaf
Issue Type: Dependency upgrade
Components: karaf
Reporter: Jean-Baptiste Onofré
Assignee: Jean-Baptiste Onofré
When building Karaf on kubernetes (on a pod), the {{resolverParallelism}} can
be "bad" depending of the number of vCPU and the features dependencies.
The {{resolverParallelism}} is computed like this:
{code:java}
int resolverParallelism = Math.max(1,
Runtime.getRuntime().availableProcessors()); {code}
Actually, if the features are not really sequential (features dependencies),
the resolution will fail with 1 (if we have a single vCPU). The default should
be at least 2.
It's better to use {{-1}} by default and then using resolver with default
parallelism, and let the user defines the {{resolverParallelism}} by parameter.
