Hi list,
I would like to backport:
http://jira.codehaus.org/browse/GEOT-4763
Improve scalability on Rendering/RasterSymbolizer
Long story short, this improvement contains a couple of updates which:
- minimize the lookup for GridCoverageFactory by checking hints first
- remove synchronizations from the rendering processing nodes.
Note that all usages of these processing nodes are made through the
instantiation of a RasterSymbolizerHelper class on top of a coverage, to be
then executed and "visited" with a RasterSymbolizer instance so that
ProcessingNode methods will not be invoked concurrently on the same
ProcessingNode instance.
Please, let me know what do you think about it.
Cheers,
Daniele
