Crate avz 

avz

A blistering-fast Avro CLI tool — a modern replacement for Java’s avro-tools and Python’s fastavro.

Features

• Read & inspect: cat, head, schema, count, meta, fingerprint, validate
• Search: grep with regex or fixed-string matching across entire Avro records
• Transform: fromjson, concat, recodec
• Generate: random test data from any Avro schema
• I/O sources: local files, glob patterns, and S3 URIs (with glob support)
• Codecs: null, deflate, snappy, zstandard, bzip2, xz
• Output: colorized JSON with automatic pager for large output

Installation

cargo install avz

Usage

# peek at records
avz head -n 5 data.avro --pretty

# search for a record
avz grep "user_id.*12345" data.avro

# count records across S3
avz count "s3://bucket/prefix/*.avro"

# convert JSON to Avro
avz fromjson --schema schema.json --output data.avro input.jsonl
