Enum CompressionType 

pub enum CompressionType {
    None,
    Zstd,
    Lz4,
}

Compression algorithm applied to Arrow IPC record batches sent over gRPC.

Compression is negotiated per-stream: the server applies the chosen codec when encoding IPC buffers with FlightDataEncoderBuilder.

Choosing a codec

• Use Zstd for most deployments — it offers the best size/CPU tradeoff for typical columnar workloads and is the default.
• Use Lz4 when the client is CPU-constrained and decompression speed matters more than wire size.
• Use None on loopback / LAN links where network bandwidth is not a bottleneck and you want zero codec overhead.

Variants

None

No compression. Zero CPU cost; highest wire size.

Suitable for loopback or high-bandwidth LAN deployments where encoding overhead outweighs any bandwidth saving.

Zstd

Zstandard compression (the default).

Best size/CPU tradeoff for typical columnar Arrow workloads. Zstd achieves higher compression ratios than LZ4 at comparable or lower decompression cost, making it the right default for most deployments.

Lz4

LZ4 (frame format) compression.

Faster decompression than Zstd at the cost of a larger wire footprint. Prefer this when the client is CPU-constrained and decompression speed is more important than reducing bytes on the wire.
