Class MigrateDatabase6To100

java.lang.Object

com.cloudant.sync.datastore.migrations.MigrateDatabase6To100

All Implemented Interfaces:

Migration

public class MigrateDatabase6To100
extends java.lang.Object
implements Migration

Migration from datastore JSON database version 6 to 100, which requires migration of data between tables with a transform in Java code along the way. This change is a breaking change because after the migration, older versions of the code will not be able to find attachments on disk because they will look for the path based on the hex of the key rather than going via the attachments table.
