次の例では、Avroオブジェクト コンテナ内のファイルを表わすBLOBのテーブルにAvroContainerSplitを使用しています。
/* Create a table that contains the container objects */
CREATE TABLE containers(id INTEGER, container BLOB);
/* Load one or more containers into the containers table via
the utility of your choice. */
/* Create a table that will receive the individual Avro objects
from the AvroContainerSplit table operator. */
CREATE TABLE avro_table(
container_id INTEGER,
avro_id INTEGER,
avro_val DATASET(8000) STORAGE FORMAT AVRO);
/* Invoke the table operator to split up the container. */
INSERT INTO avro_table
SELECT T.out_container_id, T.avro_object_id, T.avro_value
FROM AvroContainerSplit (ON (SELECT id, container FROM containers)) T;
/* Select out the individual Avro values in the JSON format. */
SELECT container_id, avro_id, avro_val.ToJson()
FROM avro_table
ORDER BY container_id, avro_id;
