* be made against the latest append in the current entry. New appends will replace older appends
|

* in the current entry so that the space overhead is constant.
|

* @param origin Indicates the origin of the append which implies the extent of validation. For example, offset

* commits, which originate from the group coordinator, do not have sequence numbers and therefore
|
||||
* only producer epoch validation is done. Appends which come through replication are not validated
