Hi,

Below are the two tables where initial data will be near 47 Millon ,then per day transaction will be 1 millon. Is my below structure ok or do i need to change something to support this process.

CREATE TABLE "C360_DWH_VER"."F_CUSTOMER_TRANSACTION"

   (                      "TRANSACTION_ID" VARCHAR2(20 BYTE) NOT NULL ENABLE,

                          "D_STORE_KEY" NUMBER(20,0) NOT NULL ENABLE,

                          "TRANSACTION_TIMESTAMP" VARCHAR2(14 BYTE) NOT NULL ENABLE,

                          "D_MODE_OF_PAYMENT_KEY" NUMBER(20,0) NOT NULL ENABLE,

                          "D_TIME_KEY" NUMBER(5,0) NOT NULL ENABLE,

                          "TRANSACTION_DATE_KEY" NUMBER(20,0) NOT NULL ENABLE,

                          "TRANSACTION_VALUE" NUMBER(18,4) NOT NULL ENABLE,

                          "VAT_AMOUNT" NUMBER(18,4) NOT NULL ENABLE,

Howdy, Stranger!
