Настройка производительности хранилища данных: оптимизация производительности MERGE, связанная с большими и широкими таблицами.

Аннотация: В этой статье в основном объясняется процесс оптимизации производительности MERGE, связанный с большими и широкими таблицами в процессе оптимизации производительности хранилища данных.

Эта статья предоставлена ​​облачным сообществом Huawei « Настройка производительности GaussDB (DWS): оптимизация производительности ассоциации больших широких таблиц MERGE », автор: Qi Li Ge File.

【Анализ производительности】

Анализируя план выполнения (следующим образом), выясняется, что таблицы sdifin.hah_ae_line_sr_t_02_8663 и stgfin.dlt_hah_ae_line_sr_t_02_8663 представляют собой большие широкие таблицы с 3+ миллиардами данных, а ширина одного поля достигает 15К. Связанный набор результатов необходимо перераспределить перед выполнением операции MERGE.Объем данных этого перераспределения также составляет 300 миллионов данных, а ширина одного поля составляет 30 КБ (в основном сумма ширины полей таблиц sdifin.hah_ae_line_sr_t_02_8663 и stgfin. dlt_hah_ae_line_sr_t_02_8663).

Разделите оператор MERGE на два проанализированных набора результатов, UPDATE и INSERT, и независимо вставьте их в целевую таблицу. Поскольку в приведенном выше варианте использования слишком много столбцов, конструкция громоздка, и для демонстрации используется следующий вариант использования.

CREATE TABLE t(a int, b text, c text, d text) WITH(orientation=column) DISTRIBUTE BY HASH(a);
CREATE TABLE tmp(a int, b text, c text, d text) WITH(orientation=column) DISTRIBUTE BY HASH(a);

Исходный оператор MERGE

MERGE INTO t USING tmp ON tmp.a = t.a
WHEN MATCHED THEN UPDATE SET b = tmp.b, c = tmp.c
WHEN NOT MATCHED THEN INSERT (a, b, c, d) VALUES (tmp.a, tmp.b, tmp.c, tmp.d);

переписанное заявление

TRUNCATE t;
INSERT INTO t
SELECT
 * 
FROM(
 SELECT
 t.a, tmp.b, tmp.c, t.d
 FROM t
 INNER JOIN tmp ON tmp.a = t.a
 UNION ALL
 SELECT
 tmp.a, tmp.b, tmp.c, tmp.d
 FROM tmp
 WHERE NOT EXISTS(SELECT 1 FROM t WHERE t.a = tmp.a)
);

Характеристики выполнения этого оператора следующие

1. Когда вышеуказанная ветвь UNION ALL связана, читаются только необновленные столбцы a и d на public.t
2. Когда ветвь UNION ALL связана, читайте только столбец связанного столбца a на public.t
3. Ширина набора результатов каждой части оператора запроса ниже INSERT в основном соответствует ширине таблиц tmp и t.
