We all know the builtin golang JSON parser is slow. How about doing comparisons against other implementations? Like this one: https://github.com/json-iterator/go Update: found this outdated repo: https://github.com/ohler55/compare-go-json

In A Journey building a fast JSON parser and full JSONPath

peterohler·Apr 15, 2022

For some specific cases simdjson might be the fastest but it does fare as well in other cases as seen here: https://github.com/ohler55/compare-go-json or here: https://github.com/ohler55/ojc/blob/master/misc/compete.md. Parsing the JSON file is only part of the solution though. There needs to be an efficient and easy way to extract the data of interest. OjG (https://github.com/ohler55/ojg) has a JSONPath implementation for that. Written in go is a high performer.

For me OjG (https://github.com/ohler55/ojg) has been great. I regularly use it on files that can not be loaded into memory. The best JSON file format for multiple record is one JSON document per record all in the same file. OjG doesn't care if they are on different lines. It is fast (https://github.com/ohler55/compare-go-json) and uses a fairly complete JSONPath implementation for searches. Similar to jq but using JSONPath instead of a proprietary query language. I am biased though as I wrote OjG to handle what other tools were not able to do.

Have you compare it to OjG (https://github.com/ohler55/ojg)? You could also add your parser to https://github.com/ohler55/compare-go-json.
