Feature enhancement: Adding Pool.broadcast() for sending some data to all child workers #185
Description
Hi,
It would be a useful feature if there could be a way to send some data to all of the child workers in a pool. Something like Pool.broadcast() function would work. This could be really useful in scenarios when some initial data needs to be sent to a worker before starting any actual work.
Thanks

Thanks for your suggestion Stainlee.
I think your idea is similar to what is discussed in #65. If so let's please continue the discussion there.

is there a plan to use worker_thread broadcastchannel, which make all worker recevie a broadcast message and do some actions.

I'm open to pull requests implementing this (see also #65).

I know this is old, but is there any plan to merge this pull request ? That would be useful I agree 😄 Although I do think the
broadcastwould be useful in other scenarios, not be only for initialization.In my case, I use SQLite workers, and I'd need to send something to all workers periodically to update the connections. That's very specific, but I don't see why it should be limited to startup of workers only.
