How to make all seastar shards stackfull coroutines?

[kelbon]

seastar::thread (async) allows to .get seastar::future, but there are no docs about how to start all shards as seastar::threads

[xemul]

Something like

    smp::invoke_on_all([] {
        return seastar::async([] {
            /* your lambda here */
        });
    });

should work
