Class RowCell

java.lang.Object

com.google.cloud.bigtable.hbase.adapters.read.RowCell

All Implemented Interfaces:

org.apache.hadoop.hbase.Cell

@InternalApi(value="For internal usage only")
public class RowCell
extends Object
implements org.apache.hadoop.hbase.Cell

RowCell is an alternative implementation of KeyValue. Unlike KeyValue, RowCell stores each value separately, which minimizes the number of copies that need to be made when unpacking the results from the Cloud Bigtable api.

This implementation is a few microseconds quicker than KeyValue, which makes a big performance difference for large scans.

For internal use only - public for technical reasons.
