Examples with HashFunction org.apache.flink.table.runtime.generated.HashFunction used on opensource projects

Example 1 with HashFunction

use of org.apache.flink.table.runtime.generated.HashFunction in project flink by apache.

the class CodeSplitTest method testHashFunction.

@Test
public void testHashFunction() {
    int numFields = 1000;
    RowType rowType = getIntRowType(numFields);
    int[] hashFields = new int[numFields];
    for (int i = 0; i < numFields; i++) {
        hashFields[i] = i;
    }
    GenericRowData rowData = new GenericRowData(numFields);
    for (int i = 0; i < numFields; i++) {
        rowData.setField(i, i);
    }
    Consumer<TableConfig> consumer = tableConfig -> {
        HashFunction instance = HashCodeGenerator.generateRowHash(new CodeGeneratorContext(tableConfig), rowType, "", hashFields).newInstance(classLoader);
        for (int i = 0; i < 100; i++) {
            Assert.assertEquals(-1433414860, instance.hashCode(rowData));
        }
    };
    runTest(consumer);
}
