" This is inspired by #6781. The idea is to make Scylla listen for CQL connections on port 9042 (where both old shard-aware and shard-unaware clients can still connect the traditional way). On top of that I added a new port, where everything works the same way, only the port from client's socket used to determine the shard No. to connect to. Desired shard No. is the result of `clientside_port % num_shards`. The new port is configurable from scylla.yaml and defaults to 19042 (unencrypted, unless user configures encryption options and omits `native_shard_aware_transport_port_ssl` in DB config). Two "SUPPORTED" tags are added: "SCYLLA_SHARD_AWARE_PORT" and "SCYLLA_SHARD_AWARE_PORT_SSL". For compatibility, "SCYLLA_SHARDING_ALGORITHM" is still kept. Fixes #5239 " * jul-stas-shard-aware-listener: docs: Info about shard-aware listeners in protocol-extensions transport: Added listener with port-based load balancing
