Looking for: library to turn SQL (or abstracted) to code & execute against custom backend (slice of structs)
It seems that you're looking for something like https://github.com/npgall/cqengine but unfortunately I'm not aware of any equivalent in Go. LINQ is similar. I'd probably try searching for "LINQ in go" or something like that.

Evaluating Range Predicates over Java collections
I wonder if there's a huge difference in efficiency between RoaringBitmap and CQEngine. I used CQEngine a few years back and it turned out really great. Never tried RoaringBitmap, though.

What you need to know about the future of Mozilla Hubs
Yes, let's hope! The strategy has worked out sometimes - Google shut down 'Google Refine' 10 years ago, it got turned into 'Open Refine', last update 2 months ago. https://github.com/OpenRefine/OpenRefine
It's a hugely useful tool if you're working with messy Excel-scale data, i.e., most biologists or social scientists.

java string equals returns false, even for identical strings
EDIT: trim() does not remove unicode 0x200b (unicode character for zero width space). https://github.com/OpenRefine/OpenRefine/issues/5105 is worth a read.

UIUC MCS - CS 513 Review - Theory and Practice of Data Cleaning
There were six homework assignments. In order they were Regular Expressions, OpenRefine, Datalog, SQL, Provenance, and Python. None of these assignments took more than two to three hours to complete. They all were basic implementation and programming assignments with autograders.

"We have great datasets"
Open Refine will get you about 70% there. It's FOSS

Is there any tools to streamline data cleaning process?
I’ve heard good things about https://openrefine.org/

What is the best approach to removing duplicate person records if the only identifier is person firstname middle name and last name? These names are entered in varying ways to the DB, thus they are free-fromatted.
It's not suited to SQL, use Open Refine or python fuzzywuzzy.
