接口概要

接口	说明
Cell	The unit of storage in HBase consisting of the following fields: 1) row 2) column family 3) column qualifier 4) timestamp 5) type 6) MVCC version 7) value Uniqueness is determined by the combination of row, column family, column qualifier, timestamp, and type.
CellScannable	Implementer can return a CellScanner over its Cell content.
CellScanner	An interface for iterating through a sequence of cells.
KeyValue.SamePrefixComparator<T>	Avoids redundant comparisons for better performance.
SettableSequenceId	Using this Interface one can mark a Cell as Sequence stampable.
SettableTimestamp	Using this Interface one can mark a Cell as timestamp changeable.
Stoppable	Implementers are Stoppable.
