Toy Key-Value store

This library provides an easy to use interface to PebbleDB. The original interface is designed for high performance, so, for example, it returns slices of internal slabs. It also provides lots of knobs to optimize inner wokings of the databale. That is not necessary in 80% of cases, but adds plenty of boilerplate. ToyKV hides that behind a slim API. The raw interface is still available though, see the DB field.

ToyKV also imposes basic store orgatization: the type of a record is specified by one letter, the key is any Stringer (e.g. time or IP address), the value is a string. The key difference of golang's []byte and string is immutability, so unless you are concerned about performance, you take the safe path and use string.

ToyKV supports two consistency levels: sync and best effort. The sync mode employs WAL and waits each commit to be reliably stored. The best effort mode (no WAL, no wait) may forget recent writes in case of a crash. To run in the sync mode, name your database dir with the".db" extension, e.g. Open("name.db"). For the best effort mode, name the dir in some other way.

See the tests for API usage examples.
