Spring Data Redis provides certain components that are the cornerstones of each application that uses it. This section provides a brief introduction to the components that we will later use to implement our example applications.
Atomic counters are for Redis what sequences are for relational databases. Atomic counters guarantee that the value received by a client is unique. This makes these counters a perfect tool for creating unique IDs to our data that is stored in Redis. At the moment, Spring Data Redis offers two atomic counters:
. These classes provide atomic counter operations for integers and longs.
RedisTemplate<K,V> class is the central component of Spring Data Redis. It provides methods that we can use to communicate with a Redis instance. This class requires that two type parameters are given during its instantiation: the type of used Redis key and the type of the Redis value.
