Strings in argumenttimestamps in argumentDeleteRequest
that is created with a specific timestamp in argument will only delete
values in HBase that were previously stored with a timestamp less than
or equal to that of the DeleteRequest unless
setDeleteAtTimestampOnly(boolean) is also called, in which case only the
value at the specified timestamp is deleted.HBaseRpc.HasFamily, HBaseRpc.HasKey, HBaseRpc.HasQualifier, HBaseRpc.HasQualifiers, HBaseRpc.HasTable, HBaseRpc.HasTimestamp, HBaseRpc.HasValue, HBaseRpc.HasValues| Modifier and Type | Field and Description |

Setting this to false bypasses the client-side buffering, which
is used to send RPCs in batches for greater throughput, and causes this
RPC to be sent directly to the server.
