Example 2 with IncrementBuilder

use of co.cask.cdap.data2.util.hbase.IncrementBuilder in project cdap by caskdata.

the class HBaseTable method getIncrement.

    if (existing != null) {
        return existing;
    }
    IncrementBuilder builder = tableUtil.buildIncrement(row).setAttribute(DELTA_WRITE, Bytes.toBytes(true));
