I need a way to store mass amounts of data to a file efficiently. I am currently using YAML and it causes servers to lag because the plugin is storing so much data (block breaks, basically). I am wondering if there is a library or some piece of code that I could use to store data in a fast, efficient way. I also don't want the server owner to be able to open the file (although thats not a deal breaker for me). If anyone has tips and/or libraries I could use, I'd appreciate it!
