I used BDB as a Win32 profiler backend. The profiler was lightweight and would write a flat file with profiling data and function addresses to keep the captured data small.

A post processing tool would read the profiler data and create a BDB file with support for extracting call graphs and topN sort of analysis.

The final GUI was implemented in Visual Basic since other developers would not use the TUI/CLI based tools in console.

The next project used BDB to store file system metadata on embedded NAS storage. We implemented a fast ‘find’ like service based on file metadata (stat fields) stored in BDB with support for user defined file metadata.
