I am proficient in Python but beginner in Java and since Python is not supported - looking for a working example-code in Java or NodeJS (not Documentation which has snippets and partial code) about how to store JSON into Apache Ignite cache and then query any field (with field query).
Problem is that JSON can have different structure every time (one time can have 3 fields, next time 30 fields), all controlled by user.
Is there any working example showing the whole process from beginning (JSON from some file) to the end (Ignite cache)?
