📝 Walkthrough

Walkthrough

Introduces configurable chunk size management across the application. A new chunk_size setting is added to the configuration layer (parsed from CHUNK_SIZE_MB environment variable with 1-10 MiB validation), then used to replace fixed buffer sizes in stream handling and TUS protocol implementations.

Changes

Cohort / File(s)	Summary
Configuration Management docker-compose.yml, src/settings.rs	Added CHUNK_SIZE_MB environment variable (default 1 MiB, range 1-10) to docker-compose.yml. Extended Settings struct with new chunk_size field (computed in bytes) and implemented environment-based parsing with range validation.
Stream Handling src/utils/stream.rs	Replaced tokio_util::io::ReaderStream with manual async_stream::stream! implementation that allocates buffers sized to CONFIG.chunk_size and yields chunks asynchronously. Simplified error handling by returning raw tokio read errors.
TUS Protocol Integration src/utils/tus.rs	Removed fixed PATCH_CHUNK_SIZE constant and replaced with configurable CONFIG.chunk_size for determining sub-chunk sizes during TUS PATCH operations.

Poem

🐰 Chunks of data, now so small,
Config whispers to them all,
From one to ten, we dance with glee,
Streams and patches, wild and free!
Configurable dreams come true, hooray! 🎉
