min vs minIdle

[mattfysh]

hey there, thanks for this brilliant library! i'm looking at the options and i guess not understanding the difference between min and minIdle, perhaps I thought all resources were idle if they were in the pool - can they be in other states?

Hi,
The "min" option determines the minimum number of resources in the pool. These resources may be idle or active.
For example, min is 2. Pool starts with 2 idle resources. When you call acquire pool does nothing. So you have 2 resources now, 1 active 1 idle.

The "minIdle" option determines the minimum number of idle resources in the pool. For example, minIdle is 2. Pool starts with 2 idle resources. When you call acquire, a new resource is created immediately to keep minimum idle resouce count (2). So you have 3 resources now, 1 active 2 idle.
