44 * Originally written PE3617
47 * History is a special case, because we don't want Updates or Deletes... Too likely to mess up history.
49 * Jonathan 9-9-2013 - Found a problem with using "Prepare". You cannot prepare anything with a "now()" in it, as
50 * it is evaluated once during the prepare, and kept. That renders any use of "now()" pointless. Therefore
51 * the Create function needs to be run fresh everytime.
53 * Fixed in Cassandra 1.2.6 https://issues.apache.org/jira/browse/CASSANDRA-5616
