What is Lightning Memory Mapped Database (LMDB)?
Poking around at your post/comment history, maybe this will be relevant: here's a scraper that downloads option chains and sticks them into PostgreSQL. Each day, 600 MB worth of HTML data are downloaded, parsed, and stuck into PostgreSQL. It handles this just fine.

What is Lightning Memory Mapped Database (LMDB)?
I may have jumped the gun for the list of programming languages, because I found the list right before you sent this. I am currently on the github readme for node. https://github.com/Venemo/node-lmdb. I really appreciate it. Thank you for all the other knowledge too. Hopefully I can figure this out and utilize it.
