Struct RetainedVerifiedActivatedAck 

pub struct RetainedVerifiedActivatedAck {
    pub acknowledgement: (StoreAckRef, StoreAck),
    pub activating_commit: StoreBatchCommitRef,
}

The acknowledgement one commit activated, retained beside that commit.

One acknowledgement, not the chain behind it. A retained row describes its own commit, and an acknowledgement’s predecessors are described by the rows that retained them — each acknowledgement names its predecessor’s object, so contiguity follows from the rows in the same way a commit’s ancestry follows from the commits, without every row carrying a copy of everything before it.

Storing the chain here instead made a retained row grow with the history in front of it: on a two-device store where nearly every commit acknowledges, the row at sequence N held N acknowledgements, so the table grew with the square of the history. A field store reached 223 MB over 385 rows, and both applying a commit and reading the retained rows back paid for it.

Fields

acknowledgement: (StoreAckRef, StoreAck)

activating_commit: StoreBatchCommitRef
