RowCell (Cloud Bigtable HBase Client for Java 1.12.0 API)

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

Class RowCell

• java.lang.Object
• • com.google.cloud.bigtable.hbase.adapters.read.RowCell

• All Implemented Interfaces:

  Cell

  ---

  
  

  public class RowCell
  extends Object
  implements Cell

  This implementation of Cell is more efficient for Bigtable scanning than KeyValue . RowCell is pretty straight forward. Each *Array() method returns the array passed in in the constructor. Each *Offset() method returns 0. Each *Length() returns the length of the array. This implementation is a few microseconds quicker thank KeyValue, which makes a big performance difference for large scans.
