【パフォーマンス分析】

実行プランを分析すると (次のように)、テーブル sdifin.hah_ae_line_sr_t_02_8663 および stgfin.dlt_hah_ae_line_sr_t_02_8663 は 30 億を超えるデータを含む大きな幅のテーブルであり、単一フィールドの幅は 15K に達することがわかります。関連する結果セットは、MERGE 操作を実行する前に再配布する必要があります。この再配布のデータ量も 3 億データで、単一フィールド幅は 30K (基本的に、テーブル sdifin.hah_ae_line_sr_t_02_8663 と stgfin のフィールド幅の合計) です。 dlt_hah_ae_line_sr_t_02_8663)。

【最適化のご提案】

MERGE ステートメントを 2 つの分析結果セット (UPDATE と INSERT) に分割し、それらをターゲット テーブルに個別に挿入します。上記のユースケースは列が多すぎるため構築が面倒なので、以下のユースケースをデモに使用します。

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);

元の MERGE ステートメント

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);

書き換えられた声明

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)
);

このステートメントの実行特性は次のとおりです。

  1. 上記の UNION ALL 分岐が関連付けられている場合、public.t の更新されていない列 a と d のみが読み取られます。
  2. UNION ALL のブランチが関連付けられている場合、public.t の関連付けられたカラム column a のみを読み取ります。
  3. INSERT 以下のクエリ ステートメントの各部分の結果セットの幅は、基本的にテーブル tmp および t の幅と一致します。
