    • streamPartition

      public ReadChangeStreamQuery streamPartition(@Nonnull RowRange rowRange)
      Adds a partition.
      Parameters:
      rowRange - Represents the partition in the form [startKey, endKey). startKey can be null to represent negative infinity. endKey can be null to represent positive infinity.
