IO or YAML data storage?

(Before I begin, I specifially don't want to use SQL or MySQL. I have no idea how it works and I rather not learn.)

I need a way or thought process on how to store block locations in a file. Right now I'm using the plugin's config, and 1) I don't want people looking in it and seeing a mess (2) Its extremely inefficient. Causing way too much lag.

If there is no way to store block locations fast (as in 5 locations each second or more) and efficiently, I don't know what to do. I've thought of using a database but I can't find any libraries out there AND I don't know how it works. If someone is out there and knows how to store block locations efficiently, PLEASE HELP xD

 

Try multithreading it; just google "multithread Java".
Due note that only a handful of methods in Bukkit are thread-safe.

Learn SQL, Put it this way, the more you learn, the more you'll have to work with!

 

What TomFromCollege said, also Bukkit.getScheduler().runAsyncTask(...)

Well what I want is a fast, lag-free way to store data so I can use it later...

 

How many blocks do you expect to store? Because unless it's a really small number you need SQL. And either way you need runAsyncTask(...).
