| | 31 | Redis takes the whole dataset in memory and <a href="Persistence.html">writes asynchronously to disk</a> in order to be very fast, you have the best of both worlds: hyper-speed and <a href="Persistence.html">persistence</a> for your data.<br/><br/>Establishing a new connection to a Redis Server is <i>simple</i> and <i>fast</i> nothing more that a TCP three way handshake. There is no authentication or other handshake involved (<a href="http://groups.google.com/group/redis-db/browse_thread/thread/1adb93f0b6a1460a" target="_blank">Google Group: Can we use connection pool in Redis?</a>) You can read more about the way Redis clients communicate with servers in the <a href="ProtocolSpecification.html">Protocol Specification</a>.<br/><br/>On most commodity hardware it takes about 45 seconds to restore a 2 GB database, without fancy RAID. This can give you some kind of feeling about the order of magnitude of the time needed to load data when you restart the server, so restarting a server is fast too.<br/><br/>Also <a href="Replication.html">Replication</a> is fast, benchamarks will give you the the same order of magnitude a restart does (<a href="http://groups.google.com/group/redis-db/browse_thread/thread/3ab1c8b2126f1b8/29bdb6c5973f0388?lnk=gst&q=replication+#29bdb6c5973f0388" target="_blank">Google Group: Replication speed benchmak</a>) |
