# Summary - Fixes restatedev#4456 by making sure: - Request stream is closed immediately after the we receive a terminal state - Drain the response stream. This also fixes a connection thrashing issue
## Summary - Introduce Connection<C>, a Tower Service-based HTTP/2 connection that multiplexes requests over a single H2 session with semaphore-backed concurrency control - Add TcpConnector service and ConnectionInfo/IntoConnectionInfo abstractions for URI-based TCP connection establishment
## Summary - Add AuthorityPool<C> that manages multiple H2 connections to a single authority (scheme+host+port), creating connections on demand when streams are exhausted and evicting failed ones - Add Pool<C> that routes requests to the correct AuthorityPool via a DashMap<ConnectionInfo, AuthorityPool<C>> - Add PoolBuilder with configurable max_connections and init_max_streams per authority
- This PR finally enable using of the new H2 pool in the http service client.
