  1. case class PrefixScan(prefix: String) extends ScanType with Product with Serializable
  2. case class RangeScan(from: Option[ScanTerm], to: Option[ScanTerm]) extends ScanType with Product with Serializable

    Scans documents, from document from to document to.

    Scans documents, from document from to document to.

    If None is specified for from, it indicates to scan from the start of the collection. If None is specified for to, it indicates to scan to the start of the collection.

  3. case class SamplingScan(limit: Long, seed: Long = Random.nextLong()) extends ScanType with Product with Serializable

    Samples documents randomly from the collection until reaching limit documents.

    Samples documents randomly from the collection until reaching limit documents.

    seed

    seed for the random number generator that selects the documents. If not specified, defaults to a random number. CAVEAT: Specifying the same seed does not guarantee the same documents are selected.
