public class Http2MultiplexedChannelPool extends Object implements SdkChannelPool
ChannelPool
implementation that handles multiplexed streams. Child channels are created for each HTTP/2 stream usingHttp2StreamChannelBootstrap
with the parent channel being the actual socket channel. This implementation assumes that all connections have the same setting for MAX_CONCURRENT_STREAMS. Concurrent requests are load balanced across all available connections, when the max concurrency for a connection is reached then a new connection will be opened.Note: This enforces no max concurrency. Relies on being wrapped with a
BetterFixedChannelPool
to enforce max concurrency which gives a bunch of other good features like timeouts, max pending acquires, etc.
