Hi everybody,

FYI I have just tried OFP cluster test with "tell-based" protocol:

https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/openflowplugin-csit-3node-clustering-only-neon/180/robot-plugin/log.html.gz

My observations:

1) node/port down events do not clear links in topology, this is why all topology check test fail.

2) some WARNs are flooding the log:

2019-02-12T00:26:30,055 | WARN | opendaylight-cluster-data-shard-dispatcher-33 | FrontendClientMetadataBuilder | 223 - org.opendaylight.controller.sal-distributed-datastore - 1.9.0.SNAPSHOT | member-1-shard-inventory-operational: Unknown history for aborted transaction member-1-datastore-operational-fe-0-txn-30-2, ignoring

3) The cluster perf test does not pass: https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/openflowplugin-csit-3node-clustering-perf-bulkomatic-only-neon/180/robot-plugin/log.html.gz

I do not know if we still pursue to switch the cluster protocols, at least after this test it does not seem an straight forward change.
