Documentation for persistent-cache-cpp-dev

This API provides a cache of key-value pairs with a backing store. It is intended for caching arbitrary (possibly large) amounts of data, such as might be needed by a web browser cache. The cache supports both least-recently-used and time-to-live expiration policies. It scales to large numbers (millions) of entries and is very fast. The implementation is based on leveldb and typically provides throughput many times larger than the I/O bandwidth to disk.

The cache is robust in the face of crashes and power loss. After a re-start, it is guaranteed to be in a consistent state with correct data. Some number of updates that were made just prior to a power loss or kernel crash can be lost; however, if just the calling process crashes, all updates that were made prior to the crash are guaranteed to be on disk.

This package provides examples and the API reference.
