Enum SourceReplayOrder 

Source 
pub enum SourceReplayOrder {
    Unspecified,
    SingleChannel,
    SingleChannelFixedBatches,
}
Expand description

Row order and batch boundaries reproduced when resuming a source cursor.

This is separate from row positions and delivery guarantees. The runtime must enforce the declared batch boundaries before relying on them for input/timer replay.

Variants§

§

Unspecified

The source does not promise a replay order.

§

SingleChannel

One physical input channel reproduces the same ordered suffix from a committed cursor, including the order of different keys. Poll size and timing must not reorder rows, and recovery must retain the channel identity. Independent-channel merging is excluded; this raw row-order promise does not reproduce watermark cuts.

§

SingleChannelFixedBatches

One global physical channel, with the same ordered rows in the same nonempty batches after a committed cursor. Poll limits and timing must not change batch membership. The channel may move between nodes under splittable placement; independent channels are excluded. Deterministic row positions and bounded atomic batches are required.

Process-function execution treats each batch as one input/watermark cut. The engine derives event-time progress from that batch and excludes external and wall-clock advancement. Transport batching may change within a cut without changing its end.
