Redis is an open source, advanced key-value store in a similar vein to memcache but the dataset is non-volatile. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
Redis is a TCP server using the client-server model and what is called a Request/Response protocol.
Redis offers many different ways to do one straightforward thing: store a value (“antirez”) to a key (“redis”).
- Easy to set up.
- Native support for atomically manipulating and querying data structures such as lists and sets.
- Very simple to use and configure master-slave replication that allows slave Redis servers to be exact copies of master servers.
- Redis Virtual Memory which allows users to grow their dataset beyond RAM limitations.
- Special encoding of small aggregate data types.
- Loads and mantains the whole dataset into memory, but the dataset is persistent.
- Supports setting timeouts to keys so that this key will be automatically removed when a given amount of time passes.
- Multiple databases with commands to atomically move keys from one database to the other.
- MULTI/EXEC family of commands.
- Popping from a list in a blocking fashion.
- Publish messages onto channels and subscribe to receive all messages that are published on channels.
- Unix domain socket support.
- Syslog support.
