Discarded events are not distributed across the WAN. Regions can also be configured to distribute updates to other Geode clusters over a WAN. With a distributed WAN configuration, multiple gateway senders asynchronously queue and send region updates to another Geode cluster. It is possible for multiple sites to send updates to the same region entry at the same time. It is also possible that, due to a slow WAN connection, a cluster might receive region updates after a considerable delay, and after it has applied more recent updates to a region. To ensure that WAN-replicated regions eventually reach a consistent state, Geode first ensures that each cluster performs consistency checking to regions before queuing updates to a gateway sender for WAN distribution. In order words, region conflicts are first detected and resolved in the local cluster, using the techniques described in the previous sections. http://git-wip-us.apache.org/repos/asf/incubator-geode/blob/6bea8204/geode-docs/developing/distributed_regions/how_replication_works.html.md.erb ---------------------------------------------------------------------- diff --git a/geode-docs/developing/distributed_regions/how_replication_works.html.md.erb b/geode-docs/developing/distributed_regions/how_replication_works.html.md.erb index 73bc5e1..6d2ccc5 100644 --- a/geode-docs/developing/distributed_regions/how_replication_works.html.md.erb +++ b/geode-docs/developing/distributed_regions/how_replication_works.html.md.erb @@ -2,6 +2,23 @@ title: How Replication and Preloading Work --- +<!-- +Licensed to the Apache Software Foundation (ASF) under one or more +contributor license agreements.
