Hello there,
I offer MS WIndows based tools to process JSON , XML and other data format-based (text based) databases.
Since your database is 22 GB large, it wouldn't be wise to store it all in memory, and hence would require a programming language that can perform JSON text parsing in-memory, in small chunks at a time, or using some other algorithm; and a programming language such as C/C++ which is ideally suited to processing large databases , including this JSON database ; before querying it.
I should be able to assist, but the sample you have provided is not valid JSON, firstly; but it looks fine when visually inspected.
Do read thru My profile first, to acquaint your self with My background first, should you decide to respond to My proposal...
Cheers
Dinesh
