Examples with QueryBuilder org.apache.drill.test.QueryBuilder used on opensource projects

Example 1 with QueryBuilder

use of org.apache.drill.test.QueryBuilder in project drill by apache.

the class TestParquetLimitPushDown method testMultipleFiles.

@Test
public void testMultipleFiles() throws Exception {
    String query = "select * from dfs.`parquet/users` limit 1";
    QueryBuilder.QuerySummary summary = queryBuilder().sql(query).run();
    assertTrue(summary.succeeded());
    assertEquals(1, summary.recordCount());
    String plan = queryBuilder().sql(query).explainText();
    assertThat(plan, containsString("numRowGroups=1"));
}
