Configuring the Scheduled Task Thread Pool

Configuring the Scheduled Task Thread Pool

Tasks executed by @Scheduled are by default run on a ScheduledExecutorService that is configured to have twice the number of threads as available processors.

You can configure this thread pool as desired using application.yml, for example:

Configuring Scheduled Task Thread Pool

micronaut:
    executors:
        scheduled:
            type: scheduled
            core-pool-size: 30
