Struct AgentReadTxnStatusResponse 

pub struct AgentReadTxnStatusResponse {
    pub present: bool,
    pub state: i32,
    pub commit_ts: u64,
    pub participants: Vec<CrossShardTxnWrite>,
    pub start_ts: u64,
}

Fields

present: bool

false = no TxnStatus record present

state: i32

the decision (only meaningful when present)

commit_ts: u64

HLC commit_ts (packed u64), 0 unless committed

participants: Vec<CrossShardTxnWrite>

Every participant (cf, user_key, delete-op) the txn prewrote, so the recovery driver can fan a roll-forward / roll-back to each participant’s OWNER shard (#1598). Each participant’s delete flag records its prewrite op so a resolver can roll forward (put-vs-tombstone) without the reaped lock (#1626).

start_ts: u64

The txn’s HLC start_ts (packed u64), recorded on the status so a resolver can locate each participant’s staged value even after the lock TTL-expired (#1626).

Implementations
