Redis is an advanced key-value store. It is similar to memcached, but
|
|
the dataset is not volatile, and values can be strings (exactly like in
|
|
memcached), but also lists, sets, and ordered sets. All this data types
|
|
can be manipulated with atomic operations to push/pop elements, add/remove
|
|
elements, perform server side unions, intersections, and so forth.
|
|
In order to be very fast but at the same time persistent, the whole
|
|
dataset is taken in memory and from time to time and/or when a
|
|
number of changes to the dataset are performed, it is written
|
|
asynchronously to the disk.
