DISTRIBUTE BY

在ADB中支持分布键，DSC迁移过程中会保留对应分布键。

输入示例

     
          CREATE TABLE COPY_DI_DISTRIBUTOR_BUYER_CONTRIBUTION_RANKING_V2 (
	SHOP_ID VARCHAR ,
	DISTRIBUTOR_ID VARCHAR ,
	BUYER_ID VARCHAR ,
	DATE_TYPE BIGINT ,
	PRIMARY KEY (SHOP_ID,DISTRIBUTOR_ID,DATE_TYPE,BUYER_ID)
) DISTRIBUTE BY HASH(SHOP_ID,DISTRIBUTOR_ID,DATE_TYPE);

输出示例

     
          CREATE TABLE "public"."copy_di_distributor_buyer_contribution_ranking_v2" (
  "shop_id" VARCHAR,
  "distributor_id" VARCHAR,
  "buyer_id" VARCHAR,
  "date_type" BIGINT,
  PRIMARY KEY (
    "shop_id",
    "distributor_id",
    "date_type",
    "buyer_id"
  )
) WITH (ORIENTATION = ROW, COMPRESSION = NO) NOCOMPRESS DISTRIBUTE BY HASH (SHOP_ID, DISTRIBUTOR_ID, DATE_TYPE);
