> Switch from protobuf to json
> ----------------------------
>
> Key: SLING-9504
> URL: https://issues.apache.org/jira/browse/SLING-9504
> Project: Sling
> Issue Type: Improvement
> Components: Content Distribution
> Affects Versions: Content Distribution Journal Messages 0.1.2
> Reporter: Christian Schneider
> Assignee: Christian Schneider
> Priority: Major
> Fix For: Content Distribution Journal Kafka 0.1.6, Content
> Distribution Journal Messages 0.2.0
>
>
> Protobuf has the problem that it is difficult to diagnose. We would like to
> switch all messages to json payload.
> This is an incompatible change. So data of running instances will have to be
> migrated to the new format or old messages will be lost.
> A good way for migration is to wait until the queues are empty. This way only
> history in kafka is lost but there is no risk of inconsistencies.
