Re: Connection Pool with Erlang PB Client Necessary?

[Andrew Berman]

So I looked at a bunch of pooling applications and none of them really
have the functionality and flexibility I'm used to with Java
connection pools.  So, I created my own OTP pooling application,
Pooly.  It allows multiple pools to be configured, has flexibility on
configuring the pool (idle timeout, max age of processes, initial
count, acquire increment, max pool size, and min pool size) and
reduces the size of the pool based on the configuration parameters.

Feel free to check it out: https://github.com/aberman/pooly
