-----------------------------------
> CRS.findOperation(…) sometime slow
> ----------------------------------
>
> Key: SIS-335
> URL: https://issues.apache.org/jira/browse/SIS-335
> Project: Spatial Information Systems
> Issue Type: Bug
> Components: Referencing
> Affects Versions: 0.7
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Fix For: 0.8
>
>
> Execution of {{CRS.findOperation(sourceCRS, targetCRS, areaOfInterest)}} is
> slow when:
> * A connection to the EPSG geodetic dataset is available (which is
> recommended)
> * the given CRS have no EPSG identifiers, or their identifiers are wrong
> In such case, {{IdentifiedObjectFinder}} search the right EPSG code for the
> given CRS by scanning the EPSG database. Some conditions are put in the SQL
> {{WHERE}} clause for reducing the amount of CRS to scan, but in Apache SIS
> 0.7 those conditions are not restrictive enough, resulting in way too many
> CRS being scanned.
