Tiled Workflows

Many real workloads — GeoTIFF/COG, TileDB, map tile servers — consist of thousands of small tiles. This page covers decode-side patterns for those scenarios.

One process, many decode calls

The happy path: your process starts once and decodes tiles in a loop.

let tiles: Vec<Vec<u8>> = fetch_all_tiles()?;
let decoded: Vec<_> = tiles.iter()
    .map(|bytes| ript::decode(bytes))
    .collect::<Result<_, _>>()?;

Per-call overhead is negligible.

Avoid: one process per tile

Spawning a fresh process per tile means paying process-startup cost every time. Use a batch script or an in-process loop. Parallelism is fine; sequential spawning is not.

Parallel decode

Decode functions are thread-safe. You can call them from multiple threads without coordination. Use your favorite parallel iterator; throughput scales with cores until you hit memory bandwidth.

Pre-allocating output buffers

For uniform tile sizes, allocate once and reuse. The decoder SDK includes variants that write into a caller-owned buffer — check the header/reference bundled with the decoder download.
