%description
Sisyphus repository currently has more than 10K source packages (which is
more than 60K rpm files with subpackages). To assist repeated repo scanning
(which is required for each repo update), this package provides rpmhdrcache.so
perloadable module. This module intercepts rpmReadPackageHeader calls and
caches the result using libqacache library.

%description -n libqacache
This library implements simple key-value cache API with limited support
for concurrent reads, atomic writes, data integrity, and atime cleanup.
Small- to medium-sized cache entries (up to 32K compressed with snappy)
are stored in a Berkeley DB, larger entries are backed by filesystem.
