  String projectId = "my-project-id";

}

public static void filterComposingInterleave(
    String projectId, String instanceId, String tableId) {
  // A filter that matches cells with the value true OR with the column qualifier os_build
  Filter qualifierFilter =
      new QualifierFilter(CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes("os_build")));
  Filter valueFilter =
      new ValueFilter(CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes("true")));

  FilterList filter = new FilterList(Operator.MUST_PASS_ONE);
  filter.addFilter(qualifierFilter);
  filter.addFilter(valueFilter);

  Scan scan = new Scan().setFilter(filter).setMaxVersions();
  readWithFilter(projectId, instanceId, tableId, scan);
