software.amazon.awssdk.http.nio.netty.internal.IdleConnectionCountingChannelPool

All Implemented Interfaces:

io.netty.channel.pool.ChannelPool, Closeable, AutoCloseable, SdkChannelPool

public class IdleConnectionCountingChannelPool
extends Object
implements SdkChannelPool

A channel pool implementation that tracks the number of "idle" channels in an underlying channel pool.

Specifically, this pool counts the number of channels acquired and then released from/to the underlying channel pool. It will monitor for the underlying channels to be closed, and will remove them from the "idle" count.
