Metatile cache expiry should be linked to config reload and transaction plugins
-------------------------------------------------------------------------------
Key: GEOS-1568
URL: http://jira.codehaus.org/browse/GEOS-1568
Project: GeoServer
Issue Type: Bug
Components: WMS
Affects Versions: 1.6.0-RC1
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 1.6.0-RC2
Metatile cache expiry is fixed to 5 seconds now. This is to avoid problems with style and data changes. Yet, with big data sets this is very sub-optimal. The cache should be wiped out when the config changes (there is a global event for that) or when one of the rendered layers changes.
This can be done my making the metatile cache a transaction listener (even a dummy one, that just wipes out the cache when any layer is modified) and when the config is changed.
