Remko Popma updated LOG4J2-1326:
--------------------------------
Affects Version/s: 2.5
Component/s: API
> 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
> Components: API
> Affects Versions: 2.5
> Reporter: Vlad Shurupov
> Labels: features, performance
>
> 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.
