ContentDataStore should allow for configurable caching of metadata
------------------------------------------------------------------
Key: GEOT-2022
URL: http://jira.codehaus.org/browse/GEOT-2022
Project: GeoTools
Issue Type: Improvement
Components: data
Reporter: Andrea Aime
Assignee: Justin Deoliveira
Fix For: 2.5.0, 2.6-M0
The base class of JDBCDataStore does not cache the feature type metadata at
all. This is bad since the metadata is not going to change in the very short
range of time, and scanning jdbc metadata all time is expensive.
JDBCDataStore does cache the feature types and the type names, but not in a
controllable way (the type name cache I added by accident, but it gives a very
nice boost up to performance).
The base class should imho perform the caching, and allow the client to
forcefully reset the caches. A time based expire would be a nice extra, thought
with an explicit reset that can be emulated by the client as well.
