@InterfaceAudience.Public @InterfaceStability.Stable public class Append extends Mutation
This operation ensures atomicty to readers. Appends are done under a single row lock, so write operations to a row are synchronized, and readers are guaranteed to see this operation fully completed.
To append to a set of columns of a row, instantiate an Append object with the
row to append to. At least one column to append must be specified using the
add(byte[], byte[], byte[]) method.
