    Resolution: Duplicate

> Refactor storage protocol to use Netty instead of BIO

>                 Key: CASSANDRA-10575
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10575
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Robert Stupp
>
> Current storage protocol (everything beneath o.a.c.net) currently uses Java blocking
I/O. I.e. {{InboundTcpConnection}} and {{OutboundTcpConnection}} use a dedicated Java thread
per connection.
> Using NIO would reduce the number of threads as many threads can become a problem in
bigger clusters.
> Migrating the code to Netty seems to be a prerequisite for thread-per-core model.
> The intention of this ticket is not to change the protocol itself as CASSANDRA-8971 would
do.
