LainDB is a very simple key-value store engine. LainDB aims to be fast and flexible at the same time, so it uses modern c++ features, including nullptr and template. Therefore, LainDB needs c++11 support. However, Laindb avoids any platform-specific API and can run on any platform.

As a key-value store, you are able to store any kind of data (you may need to provide a serializer), inside a key (a c-style string with a length limitation). This data can later be retrieved only if we know the exact key used to store it. LainDB provides a minimal interface and it is easy to use but also hard to write unsafe codes.

LainDB’s index is implemented by a top-down B+tree. Cache are handled using LRU(Least Recently Used) algorithm.
