> Components: core filter
> Affects Versions: 2.5.2

> 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.
