Oded Peer commented on CASSANDRA-8755:
--------------------------------------
Java's String.split() method has a fast-path for single character input,
avoiding costly regexp creation. See http://stackoverflow.com/a/11002374/248656.
> Replace trivial uses of String.replace/replaceAll/split with StringUtils
> methods

> There are places in the code where those regex based methods are used with
> plain, not regexp, strings, so StringUtils alternatives should be faster.
