java.lang.Objectorg.cumulus4j.store.datastoreversion.AbstractDatastoreVersionCommand
org.cumulus4j.store.datastoreversion.command.RecreateIndex
public class RecreateIndex
Delete all IndexEntry
s from the datastore and then iterate all
DataEntry
s and re-index them.
TODO This class currently does not yet ensure that different keys are used. Thus, very likely the entire index uses only one single key. This should be improved in a future version.
