Struct AgentStateConditionalWriteRequest 

Source
pub struct AgentStateConditionalWriteRequest {
    pub gate: Option<WriteEntry>,
    pub condition: i32,
    pub condition_value: Vec<u8>,
    pub entries: Vec<WriteEntry>,
    pub read_set: Vec<AgentTxnRead>,
    pub condition_seq: u64,

}

Fields§

§gate: Option<WriteEntry>

Same shape as ConditionalBatchWriteRequest minus the shard fields — the shard is not the caller’s to choose here, it is the pinned coordination shard by construction.

§condition: i32§condition_value: Vec<u8>§entries: Vec<WriteEntry>§read_set: Vec<AgentTxnRead>§condition_seq: u64§role_entries: Vec<AgentStateRoleEntry>

Logical causal rows to apply alongside entries, expanded server-side. Prefer these over raw entries for anything in a causal CF.

§role_gate: Option<AgentStateRoleEntry>

The GATE, named logically. Use this instead of gate for anything in a causal CF: the coordination CF is created node-locally and is NOT in the metadata registry, so a coordinator has no way to learn its physical id — and any id it guessed would be a different CF on a different node.

The server puts the predicate on the row reads resolve to, and any additional mirror rows ride along as plain entries so the whole batch is still decided by the one predicate.

§role_read_set: Vec<AgentStateRoleRead>

Read-set entries named logically, resolved server-side and merged into read_set. Needed for the same reason role_gate is: a causal row’s physical address depends on the store’s layout, and the coordination CF has no metadata id at all — a coordinator that built these itself would either guess wrong or be unable to name the row.
