Config<A, E>Normalized configuration used by a Pool.
When to use
Use as the normalized, read-only description of how a pool acquires, sizes, shares, and resizes its items after construction.
Details
The config stores the acquire effect, size bounds, per-item concurrency, target utilization, and resizing strategy used by the pool implementation.

interface Strategy<A, E>Strategy used by a Pool to manage background resizing and item
reclamation.
When to use
Use when defining a custom pool lifecycle policy that needs to run background
work, observe acquired items, or choose items for reclamation.
Details
run starts any strategy-specific background work, onAcquire is invoked
when an item is acquired, and reclaim selects an item that can be removed
or replaced.
