- from
We can get it form the rpc::client_info
- session_index
There will always be one session in stream_coordinator::host_streaming_data with a peer.
- is_for_outgoing
In cassandra, it initiates two tcp connections, one for incoming stream and one for outgoing stream.
logger.debug("[Stream #{}] Sending stream init for incoming stream", session.planId());
logger.debug("[Stream #{}] Sending stream init for outgoing stream", session.planId());
In scylla, it only initiates one "connection" for sending, the peer initiates another "connection" for receiving.
So, is_for_outgoing will also be true in scylla, we can drop it.
- keep_ss_table_level
In scylla, again, we stream mutations instead of sstable file. It is
not relevant to us.
