redis - 5:6.0.16-1+deb11u4 main

Redis is a key-value database in a similar vein to memcache but the dataset
is non-volatile. Redis additionally provides native support for atomically
manipulating and querying data structures such as lists and sets.
.
The dataset is stored entirely in memory and periodically flushed to disk.
.
This package installs the main redis-server package.
