-------------------------------------

             Summary: Provide support for CharSequence parameters for low and zero-GC applications
                 Key: LOG4J2-1326
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1326
             Project: Log4j 2
          Issue Type: New Feature
            Reporter: Vlad Shurupov


Currently, the preferred way of logging character sequences in log4j 2 is by passing in tokens of type {{java.lang.String}}. It would be very beneficial if the API could provide methods that take {{java.lang.CharSequence}} tokens. This would allow high performance zero or low-GC applications to re-use the existing mutable structures implementing {{java.lang.CharSequence}}  for continuous logging without new objects being created.

A high-performance implementation of the logger would be expected to copy out the contents of a single or multiple instances of {{java.lang.CharSequence}} so that they could be re-used in the subsequent logging call.
