Improve spatial filter performance with Prepared Geometries
-----------------------------------------------------------
Key: GEOT-2226
URL: http://jira.codehaus.org/browse/GEOT-2226
Project: GeoTools
Issue Type: Improvement
Components: core filter
Affects Versions: 2.5.2
Reporter: Jesse Eichar
Assignee: Jesse Eichar
Priority: Minor
I need to reuse a filter many thousands of times. It is a standard use case.
One side of the filter is a literal geometry and the other is obtained from the
feature. The literal geometry is very large and could be a prepared geometry
to improve the performance characteristics of the spatial filters.
Since this is a common use case we could check the expressions and for the
literal expressions in the filter a prepared geometry could be cached and used
for the calculation.
