Struct CompressionMiddleware 

pub struct CompressionMiddleware {
    pub algorithm: Compression,
    pub max_decompressed_bytes: Option<u64>,
}

Payload-compression middleware configuration.

Compresses each message payload on the output side and decompresses it on the input side; metadata and routing keys are left untouched. Requires the compression feature. Distinct from the file/object_store batch compression field, which stays CLI-decodable at rest — this operates per message on any transport.

Fields

algorithm: Compression

Algorithm: none, gzip, lz4, or zstd. Defaults to zstd.

max_decompressed_bytes: Option<u64>

Reject a decompressed payload larger than this many bytes (decompression-bomb guard). Consumer side only; unset means no limit.
