> Gateway sender to deliver transaction events atomically to gateway receivers
> ----------------------------------------------------------------------------
>                 Key: GEODE-7971
>                 URL: https://issues.apache.org/jira/browse/GEODE-7971
>             Project: Geode
>          Issue Type: Improvement
>          Components: wan
>            Reporter: Alberto Gomez

> The goal of this ticket is to implement the necessary changes in the gateway 
> sender to prevent that events belonging to the same transaction are spread 
> across different batches. In other words, to ensure that events from the same 
> transaction are sent inside the same batch.
> This will be an optional feature on gateway senders to be enabled via a new 
> parameter (--group-transaction-events) and will be restricted to serial 
> gateway senders with just one dispatcher thread or to parallel gateway 
> senders.
> Apart from the above restriction, grouping of events for a transaction inside 
> the same batch may only be attained if the regions to which the events belong 
> are replicated by the same set of gateway senders with the 
> --group-transaction-events flag enabled. If this condition is not met, the 
> events will be correctly delivered by the gateway senders but it will not be 
> guaranteed that all events will always be sent inside the same batch.
