---------------------------------------
Summary: give streaming_socket_timeout_in_ms a non-zero default
Key: CASSANDRA-8611
URL: https://issues.apache.org/jira/browse/CASSANDRA-8611
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jeremy Hanna
Sometimes as mentioned in CASSANDRA-8472 streams will hang. We have
streaming_socket_timeout_in_ms which can retry after a timeout. It would be
good to make a default non-zero value. We don't want to paper over problems,
but streams sometimes hang and you don't want long running streaming operations
to just fail - as in repairs or bootstraps.
streaming_socket_timeout_in_ms should be based on the tcp idle timeout so it
shouldn't be a problem to set it to on the order of minutes. Also the socket
should only be open during the actual streaming and not during operations such
as merkle tree generation. We can set it to a conservative value and people
can set it more aggressively as needed. Disabling as a default, in my opinion,
is too conservative.
