How to define thread pools (e.g. for sequencing)?

[jkraushaar]

The JSON configuration file allows me to specify a thread pool which is used e.g. for sequencing. But where are those thread pools defined? I didn't find anything in the JSON schema about thread pool configuration.

If you look at the JSON schema (modeshape/repository-config-schema.json at master · ModeShape/modeshape · GitHub) the threadPool attribute allows you to give a custom name (string) to the thread(s) that perform the sequencing work. This is the only aspect of sequencing's threads behavior that you can configure.

Thank you for your quick answer. In this case: Is there a possibility to limit the threads created by the thread pool?

One ouf our test scenarios rapidly creates 1000 files. We have a sequencer attached which calculates a checksum for those files. ModeShape seems to create 1000 threads, which leads to an OutOfMemoryException as no further native threads can be created.

ATM. this is not possible, but I've opened https://issues.jboss.org/browse/MODE-2469 which we'll handle for 4.4.
