Detailed Description

Storage on CDB files.

This is improved version of SerializedMessageIndex. It uses CDB files for storage, which means it provides random access. The CDB files are about double the size of serialized files (~7M for 50000 keys).

Loading the whole index is slower than serialized, but about the same as for database. Suitable for single-server setups where SerializedMessageIndex is too slow for loading the whole index.
