I've started preferring key-val storage over SQL. I'm hoping there's something built in that's a littler than pstore or redis. I've been doing a lot of string (de)serializing of lists and dictionaries stored in a single file. But I figured this wouldn't perform well for a large file.  So I tried using the filesystem (storing each piece of data in a file).Is the filesystem a potentially functional alternative to a database? Is there a util I can use instead?
Is there a simple key-val storage system built in?
