Updating UDx Libraries

There are two cases where you need to update libraries that you have already deployed:

• When you have upgraded Vertica to a new version that contains changes to the SDK API. For your libraries to work with the new server version, you need to recompile them with new version of the SDK. See UDx Library Compatibility with New Server Versions for more information.
• When you have made changes to your UDxs and you want to deploy these changes. Before updating your UDx library, you need to determine if you have changed the signature of any of the functions contained in the library. If you have, you need to drop the functions from the Vertica catalog before you update the library.
