Avro Viewer Keeps the File on Your Machine
A browser-local viewer for inspecting Avro object container files, embedded schemas, blocks, codecs, and decoded records.
- For
- Engineers inspecting Avro object container files
- Worth noticing
- It rejects single-object encoding and RPC messages, and verifies sync markers plus Snappy CRC-32 checksums.
Field notes
The viewer targets Avro object container format rather than treating every Avro-related encoding as interchangeable: single-object encoding and RPC messages are explicitly excluded. Its inspection surface includes the embedded writer schema, named types, logical-type annotations, blocks, codecs, and decoded records. Decoding is bounded across several levels, including nesting and collection size, while Snappy CRC-32 checksums and sync markers are verified. File contents remain in browser memory according to the page, though hosting requests still occur.
