jq is like sed for JSON data – you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine, and expect it to work.

Do you need to query large JSON structures? Do you end up coding loops to parse the JSON and identify the data that matches your query? DefiantJS offers a better way. DefiantJS extends the global JSON object with a "search" method that enables lightning-fast searches using XPath expressions. Try out the XPath Evaluator below to get the idea.

Profiling Data Throughput
Common solutions for large semi-structured data include Python iterators, multiprocessing, Hadoop, and Spark as well as proper databases like MongoDB and ElasticSearch. Two months ago we built dask.bag, a toy dask experiment for semi-structured data. Today we’ll strengthen the dask.bag project and look more deeply at performance in this space.

We measure performance with data bandwidth, usually in megabytes per second (MB/s). We’ll build intuition for why dealing with this data is costly.
