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}
My ScanQuery looks like this:
{noformat}
new ScanQuery<>((k, v) -> {
if (data1Field.value(v) == null) {
// ...
} else if (data2Field.value(v) == null) {
// ...
}
});
{noformat}
But 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:
{noformat}
new ScanQuery<>((k, v) -> {
if (data1Field.isNull(v)) {
// ...
} else if (data2Field.isNull(v)) {
// ...
}
});
{noformat}
was:

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.
