[SOLVED] Setup max-threads parameter to the Thorntail JBeret fraction

Setup max-threads parameter to the Thorntail JBeret fraction

I use JBeret Thorntail Fraction (thorntail version - 2.0.0.Final):

What is the proper way to define max-threads number?

When I set up yaml configuration:

swarm: 
  batch:
    thread-pools:
      default:
        max-threads: 20

Max thread count remains 10 (default value).

Should in this case I define my own thread pool and how to do this?

It seems that any batch fractions properties I defined are ignored and set to default values. I tried, for example:

datasources:
  data-sources:
    h2:
      driver-name: h2
      connection-url: jdbc:h2:./target/jberet-repo
      user-name: sa
      password: sa
batch:
  default-job-repository: h2
  jdbc-job-repositories:
    h2:
      data-source: h2
  thread-pools:
    batch:
      max-threads: 20

Solution

Just today, we found that we have a docs issue (see https://issues.jboss.org/browse/THORN-2364). The correct configuration keys aren't swarm.batch.*, but swarm.batch-jberet.* (or rather thorntail.* instead of swarm.* :-) ).

Knowing that, and knowing that the default thread pool isn't called default but batch, your YAML config should look like this:

swarm: 
  batch-jberet:
    thread-pools:
      batch:
        max-threads: 20
