[jira] [Commented] (CASSANDRA-8755) Replace trivial uses of String.replace/replaceAll/split with StringUtils methods

    [ https://issues.apache.org/jira/browse/CASSANDRA-8755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14526566#comment-14526566 ] 

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.

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