Examples with Schema alluxio.grpc.table.Schema used on opensource projects

Example 1 with Schema

use of alluxio.grpc.table.Schema in project alluxio by Alluxio.

the class AlluxioCatalogTest method testGetColumnStats.

@Test
public void testGetColumnStats() throws Exception {
    Schema s = schemaFromColNames("c1", "c2", "c3");
    // setup
    // Why does this API seem so counter intuitive?
    UdbTable tbl = createMockUdbTable("test", s);
    Database db = createMockDatabase("noop", "test", Collections.emptyList());
    addTableToDb(db, Table.create(db, tbl, null));
    addDbToCatalog(db);
    // basic, filter on each col
    assertEquals(1, mCatalog.getTableColumnStatistics("test", "test", Lists.newArrayList("c1")).size());
    assertEquals(1, mCatalog.getTableColumnStatistics("test", "test", Lists.newArrayList("c2")).size());
    assertEquals(1, mCatalog.getTableColumnStatistics("test", "test", Lists.newArrayList("c3")).size());
    // try two
    assertEquals(2, mCatalog.getTableColumnStatistics("test", "test", Lists.newArrayList("c1", "c2")).size());
    // flip order
    assertEquals(2, mCatalog.getTableColumnStatistics("test", "test", Lists.newArrayList("c2", "c1")).size());
    // non existing
    assertEquals(0, mCatalog.getTableColumnStatistics("test", "test", Lists.newArrayList("doesnotexist")).size());
    // empty
    assertEquals(0, mCatalog.getTableColumnStatistics("test", "test", Lists.newArrayList()).size());
}
