Subject [jira] [Created] (CASSANDRA-9590) Support for both encrypted and unencrypted native transport connections
Date Fri, 12 Jun 2015 12:06:00 GMT
Stefan Podkowinski created CASSANDRA-9590:
---------------------------------------------

             Summary: Support for both encrypted and unencrypted native transport connections
                 Key: CASSANDRA-9590
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9590
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Stefan Podkowinski


Enabling encryption for native transport currently turns SSL exclusively on or off for the
opened socket. Migrating from plain to encrypted requires to migrate all native clients as
well and redeploy all of them at the same time after starting the SSL enabled Cassandra nodes.


This patch would allow to start Cassandra with both an unencrypted and ssl enabled native
port. Clients can connect to either, based whether they support ssl or not.

This has been implemented by introducing a new {{native_transport_port_ssl}} config option.

There would be three scenarios:
* client encryption disabled: native_transport_port unencrypted, port_ssl not used
* client encryption enabled, port_ssl not set: encrypted native_transport_port
* client encryption enabled and port_ssl set: native_transport_port unencrypted, port_ssl
encrypted

This approach would keep configuration behavior fully backwards compatible.

Patch proposal (tests will be added later in case people will speak out in favor for the patch):
[Diff trunk|https://github.com/apache/cassandra/compare/trunk...spodkowinski:feat/optionalnativessl],
