Struct AgentRollForwardRequest 

pub struct AgentRollForwardRequest {
    pub cf: u32,
    pub key: Vec<u8>,
    pub start_ts: u64,
    pub commit_ts: u64,
    pub delete: bool,
    pub read_only: bool,
}

Roll a single committed secondary forward: replace its LockRecord with a WriteRecord{commit_ts}, advance the write pointer, materialize the staged value, clear the lock. Idempotent.

Fields

cf: u32

target CF of the secondary user key

key: Vec<u8>

the secondary user key

start_ts: u64

the txn’s HLC start_ts (locates the staged value)

commit_ts: u64

the txn’s HLC commit_ts

delete: bool

The op the prewrite recorded (true = Delete/tombstone, false = Put). Carried so a resolver materializing a committed write after the lock TTL-expired does not have to consult the reaped lock to decide put-vs-tombstone (issue #1626).

read_only: bool

true = this participant was a READ intent: release the lock and write NOTHING (no value, no write-pointer, no WriteRecord). Without this the two-valued delete would make a read intent look like a Put and the roll-forward would fail closed looking for a staged value that, by design, never existed.
