Struct ProducerConfig 

#[non_exhaustive]
pub struct ProducerConfig {
    pub delta_ratio: u32,
    pub compression: bool,
}

Configuration for a Producer.

Build from Default and override fields (the struct is #[non_exhaustive], so new options stay additive): let mut config = ProducerConfig::default(); config.delta_ratio = 0;.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

delta_ratio: u32

Controls how aggressively the producer emits deltas (merge patches) instead of full snapshots.

A ratio of 0 disables deltas: every change is published as a new snapshot group.

A positive ratio enables deltas. A new snapshot group is started once the deltas already written to the current group (excluding the snapshot frame) exceed ratio times the snapshot size. The pending delta is excluded from that check, so the one that first crosses the budget still lands before the group rolls. So 1 allows roughly one snapshot’s worth of deltas before rolling, and a larger ratio tolerates more.

When compression is on, both sides of the comparison are measured on the compressed frame sizes (the real wire cost).

Defaults to 8.

compression: bool

Compress each group as one sync-flushed DEFLATE stream, so deltas reuse the snapshot as context and shrink sharply.

false (the default) writes plaintext JSON frames, identical on the wire to an uncompressed track. A Consumer reading the track must set ConsumerConfig::compression to match.
