Subject [jira] [Updated] (IGNITE-10707) BinaryField: Allow checking NULL-value without reading value
Date Mon, 17 Dec 2018 10:52:00 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-10707?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dmitry Lazurkin updated IGNITE-10707:
-------------------------------------
    Description: 
For example, there is class:
{noformat}
public class TestClass {
    public String[] data1; // many items
    public String[] data2; // many items
    // contains data in format1 for non-null data1
    // contains data in format2 for non-null data2
    public String textInfo;
}
{noformat}
In ScanQuery I would like to parse _textInfo_ without unpacking _data1_/_data2_. For now I
should retrieve full value of _data1_/_data2_, but with _BinaryField#isNull_ this task will
be faster.
