Current status of the solution is located on this PR: https://github.com/apache/geode/pull/4824

Help wanted! There is just one test failing (testExecuteOp from ConnectionPoolImplJUnitTest) that causes integration test and stress test tasks to fail. We are working to fix it, but it would be great if a more experience Geode developer takes a look. More info at the annex at the end of this page.

Gw sender failover

Solution consists on refactoring some maps on LocatorLoadSnapshot class. They use ServerLocation objects as key, this has to change due to it will not be unique for each server. We changed the maps to use InternalDistributedMember objects as key for the map entries. The ServerLocation information is not lost, as it is contained in the entry value for all the maps.

...

After checking with the dev mailing list, we received the suggestion to configure serverAffinity in Kubernetes to solve the issue with the pings, but that option broke the failover of gw senders when a gw receiver is down.
