Caution
You're viewing documentation for an unstable version of Scylla Rust Driver. Switch to the latest stable version.
Compression¶
By default the driver does not use any compression on connections.
It’s possible to specify a preferred compression algorithm.
The driver will try using it, but if the database doesn’t support it, it will fall back to no compression.
Available compression algorithms:
Snappy
LZ4
An example enabling Snappy compression algorithm:
use scylla::client::session::Session;
use scylla::client::session_builder::SessionBuilder;
use scylla::client::Compression;
use std::error::Error;
#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
let uri = std::env::var("SCYLLA_URI")
.unwrap_or_else(|_| "127.0.0.1:9042".to_string());
let session: Session = SessionBuilder::new()
.known_node(uri)
.compression(Some(Compression::Snappy))
.build()
.await?;
Ok(())
}
