berkeley-db

I'm designing a Java based web-app and I need a key-value store. Berkeley DB seems fitting enough for me, but there appears to be TWO Berkeley DBs to choose from: Berkeley DB Core which is implemented in C, and Berkeley DB Java Edition which is implemented in pure Java.

The question is, how to choose which one to use? With web-apps scalability and performance is quite important (who knows, maybe my idea will become the next Youtube), and I couldn't find easily any meaningful benchmarks between the two. I have yet to familiarize with Cores Java API, but I find it hard to believe that it could be much worse than Java Editions, which seems to be quite nice.

If some other key-value store would be much better, feel free to recommend that too. I'm storing smallish binary blobs, and keys probably will be hashes of the data, or some other unique id.

You can use most programming languages to access the API, the calls across these APIs generally mimic the Berkeley DB C-API which makes perfect sense because Berkeley DB is written in C. The inspiration… >>> More
