2.0

[devinus]

• Use an ETS table for the waiting queue
• Remove pre-17.0 support
• Remove deprecated start/1
• Remove handle_* fall-throughs
• Remove status functions, replace with sys:get_status()
• Remove non-blocking operations?
• Use a queue for the workers
• Add callback module support
• Support runtime pool size changes

Why are you going to remove support for pre-17.0?
It'd be kicking me out :(

[devinus]

@jinnipark It will only happen once 18.0 is released, at which point R16 will be two versions out of date.

The Waiting ets table is of type set so dequeues are random or rather hash based. This is interesting but likely leads to the large 99% latencies of LIFO queues because a process hashed to an unlucky bucket will effectively be at the end of the queue, with newer process jumping ahead of it.

[devinus]

I was operating based on my assumption that the first key according to the table's internal order will be returned (Erlang docs) meant there would order based on time of insertion, not hashed based on the waiting pid. That's unfortunate if that's how it works.

You will be disappointed I'm afraid :(.

Hi @devinus, I was wondering if this is still in working? Thanks
