    • scan

      default io.datarouter.scanner.Scanner<D> scan​(io.datarouter.util.tuple.Range<PK> range, Config config)
      Description copied from interface: SortedStorageReader
      The scan method accepts a Range<PK> which identifies the startKey and endKey, and returns all contiguous rows between them, not skipping or filtering any. Implementations will generally query the database in batches to avoid long transactions and huge result sets.

      When providing startKey and endKey, implementations will ignore fields after the first null. For example, when scanning a phone book with startKey:
      * (null, null) is valid and will start at the beginning of the book
      * (Corgan, null) is valid and will start at the first Corgan
      * (Corgan, Matt) is valid and will start at Corgan, Matt
      * (null, Matt) is invalid. The Matt is ignored, so it is equivalent to (null, null)

      Note that (null, Matt) will NOT do any filtering for rows with firstName=Matt. To avoid tablescans we are returning all rows in the range to the client where the client can then filter. A predicate push-down feature may be added, but it will likely use a separate interface method.
