Enum CompressionType 

Source 
pub enum CompressionType {
    None,
    Zstd,
    Lz4,
}
Expand description

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.
