Berkeley DB is a library. To use it to store data you must link the library into your application. 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…

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…

I watched a free high quality video with Aaron Hillegass about Core Data vs Tokyo Cabinet. Besides that this guy is amazingly funny (really, if you want to laugh now, watch it!), he shows off Tokyo Cabinet beeing about 40x faster than Core Data.

I have built a pretty simple REST service in Sinatra, on Rack. It's backed by 3 Tokyo Cabinet/Table datastores, which have connections that need to be opened and closed. I have two model classes written in straight Ruby that currently simply connect, get or put what they need, and then disconnect…

Is there any way I can store an array of numbers in a Tokyo Cabinet db? For example, I have predictable arrays of values such as
1 => [1, 2, 444, 0.987],
2 => [2, 23, 123, -0.234],
3 => [3, 1, 34, 1.456]
I would like to store the above in a TC fixed length db. Is there a way to store…
