record-query-1.0.4
rq
NOTE: rq
no longer ships with a Javascript engine included; instead,
it focuses exclusively on format transformation. You can still pipe into
a runtime like node.js if you need Javascript evaluation.
This is the home of the tool called rq
(record query). It's a tool
that's used for performing queries on streams of records in various
formats.
The goal is to make ad-hoc exploration of data sets easy without
having to use more heavy-weight tools like SQL/MapReduce/custom
programs. rq
fills a similar niche as tools like awk
or sed
,
but works with structured (record) data instead of text.
It was created with love out of the best parts of Rust, and is distributed as a dependency-free binary on many operating systems and architectures.
