## What it is
rq (Record Query) is a Rust command-line tool for ad-hoc analysis and transformation of streams of structured records, similar to awk/sed but for record data instead of text. It reads and writes many formats including JSON, Avro, MessagePack, YAML, TOML, CSV, CBOR, and Protobuf, and ships as a dependency-free binary.

## Use cases
- convert  to yaml from the command line
- read avro files without hadoop
- transform messagepack data to
- inspect protobuf records in a stream
- convert csv to toml
- explore structured data files ad hoc
- pipe structured records between formats in shell scripts

## When to choose
- you need a fast, dependency-free binary for converting between structured data formats
- you want awk/sed-style ad-hoc exploration of record data in the terminal
- you work with formats like Avro, MessagePack, or Protobuf that common tools don't handle

## When to avoid
- you need built-in query/JavaScript evaluation, which was removed from the tool
- you need actively developed features or timely bug fixes
- you only need JSON processing, where jq is a more mature choice
