----------------------------------
[~seanyinx]
I just want check with you about the compact events use case, it looks like we
need to store the events with different entity, here is [an
example|https://www.thoughts-on-java.org/hibernate-tips-map-multiple-entities-same-table/]
for it.
As the Entity manager cannot tell the difference of these entity, it may has
some shortcomings.

> Issue Type: Improvement
> Components: Saga
> Reporter: Yin Xiang
> Assignee: Willem Jiang
> Priority: Major
>
> only TxStartedEvent needs to contain all tx information.
> Asking other events to provide info such as payloads, compensationMethod,

> compacting events not only reduces network load and null/duplicate data in
> database
