persistent-cache-cpp-dev - 1.0.7-2 main

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.
