Hot-Swapping Reference Data for Address Verification (On-Premises)

Understanding the Reference Data Directory Structure

The reference data files currently loaded by the engine are locked on the file system level and cannot be deleted or moved while the engine is running. Therefore, both the current files and the newer files must be present at the same time for the engine to make a transition from one to the other.

To achieve this, the engine works with two directories on disk, called FileSetA and FileSetB. The directories must be direct sub-directories in the directory that the IDVEConfig.json file specifies under

</Core/System/FileSetsDirectoryPath>

Address Verification

will only accept and look for reference data in the FileSetA and FileSetB directories at the specified location.

Place the reference data files directly into FileSetA or FileSetB.

It is valid to have a single directory (either FileSetA or FileSetB) present on disk, which is typically the case if you do not intend to use hot-swapping.
