Redis
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").
Features include:
- 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
