Catching Elephant is a theme by Andy Taylor
Just finished reading a good blog post by Jonathan Ellis where he discusses some common myths that are floating around about Cassandra. The most interesting to me is his last point, where he explains that even though most of Cassandra’s data remains in memory, it writes to a commit log sot hat your data won’t be lost in the event of a catastrophic failure. Apparently the write-log technique gains the reliability of having the data on disk, but alleviates all the random seek times that a hard drive normally requires if you are simply fsyncing every piece of data you store.
