How to chose an Executor for CompletableFuture::supplyAsync

CompletableFuture::supplyAsync(() -> IO bound queries)

How do I chose an Executor for CompletableFuture::supplyAsync to avoid polluting the ForkJoinPool.commonPool().

There are many options in Executors (newCachedThreadPool, newWorkStealingPool, newFixedThreadPool etc)

And I read about new ForkJoinPool here

How do I chose the right one for my use case ?
