REPLICATION_SLOT_NAME: 복제 슬롯 이름입니다. Datastream 스트림 만들기 마법사에서 스트림을 만들 때 이 이름을 제공해야 합니다.
Datastream 사용자 만들기
Datastream 사용자를 만들려면 다음 PostgreSQL 명령어를 입력합니다.
CREATE USER USER_NAME WITH ENCRYPTED PASSWORD 'USER_PASSWORD';
다음을 바꿉니다.
USER_NAME: 만들려는 Datastream 사용자의 이름입니다.
USER_PASSWORD: 만들려는 Datastream 사용자의 비밀번호입니다.
자신이 만든 사용자에게 다음 권한을 부여합니다.
GRANT RDS_REPLICATION TO USER_NAME;
GRANT SELECT ON ALL TABLES IN SCHEMA SCHEMA_NAME TO USER_NAME;
GRANT USAGE ON SCHEMA SCHEMA_NAME TO USER_NAME;
ALTER DEFAULT PRIVILEGES IN SCHEMA SCHEMA_NAME
GRANT SELECT ON TABLES TO USER_NAME;

Launch your Amazon RDS Dashboard.\n2. In the **Navigation Drawer** , click **Parameter Groups** , and then click **Create Parameter Group** . The **Create Parameter Group** page appears.\n3. Use the following table to populate the fields of this page, and then click **Create** :\n\n4. Select the checkbox to the left of your newly created parameter group, and then, under **Parameter group actions** , click **Edit**.\n5. Change the value of the `rds.logical_replication` parameter to **1**.\n6. Click **Save Changes**.\n\nAssign the parameter group to the database instance\n---------------------------------------------------\n\n1. Launch your Amazon RDS Dashboard.\n2. In the **Navigation Drawer** , click **Databases**, and then select your database instance.\n3. From the **Instance Actions** menu, select **Modify** . The **Modify DB\n Instance** dialog appears.\n4. In the **Additional configuration** section, select the database cluster parameter group that you [created](#create-a-parameter-group-aurora).\n5. Set the **Backup retention period** to **7 days**.\n6. Click **Continue**.\n7. In the **Scheduling of modifications** pane, select the **Apply\n immediately** option.\n\nReboot the database instance\n----------------------------\n\n1. Launch your Amazon RDS Dashboard.\n2. In the **Navigation Drawer** , click **Databases**, and then select your database instance.\n3. In the **Actions** drop-down menu, select **Reboot** and then **Confirm**.\n\nCreate a publication and a replication slot\n-------------------------------------------\n\n1. Create a publication for the changes in the tables you want to replicate. We\n recommend that you create a publication only for the tables that you want to replicate.\n This allows Datastream to read-only the relevant data, and lowers the\n load on the database and Datastream:\n\n ```\n CREATE PUBLICATION PUBLICATION_NAME\n FOR TABLE SCHEMA1.TABLE1, SCHEMA2.TABLE2;\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003ePUBLICATION_NAME\u003c/var\u003e: The name of your publication. You'll need to provide this name when you create a stream in the Datastream stream creation wizard.\n - \u003cvar translate=\"no\"\u003eSCHEMA\u003c/var\u003e: The name of the schema that contains the table.\n - \u003cvar translate=\"no\"\u003eTABLE\u003c/var\u003e: The name of the table that you want to replicate.\n\n You can also create a publication for all tables in your database. Note that\n this approach increases the load on both the source database and Datastream: \n\n ```\n CREATE PUBLICATION PUBLICATION_NAME FOR ALL TABLES;\n ```\n | For PostgreSQL 15 and later, you can create a publication for all tables in a schema. This approach lets you replicate changes for tables in the specified list of schemas, including tables that you create in the future: \n |\n | ```\n | CREATE PUBLICATION PUBLICATION_NAME\n | FOR TABLES IN SCHEMA SCHEMA1, SCHEMA2;\n | ```\n2. Create a replication slot by entering the following PostgreSQL command:\n\n ```\n SELECT PG_CREATE_LOGICAL_REPLICATION_SLOT('REPLICATION_SLOT_NAME', 'pgoutput');\n ```\n\n \u003cbr /\u003e\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eREPLICATION_SLOT_NAME\u003c/var\u003e: The name of your replication slot. You'll need to provide this name when you create a stream in the Datastream stream creation wizard.\n\nCreate a Datastream user\n------------------------\n\n1. To create a Datastream user, enter the following PostgreSQL command:\n\n ```\n CREATE USER USER_NAME WITH ENCRYPTED PASSWORD 'USER_PASSWORD';\n ```\n\n \u003cbr /\u003e\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eUSER_NAME\u003c/var\u003e: The name of the Datastream user that you want to create.\n - \u003cvar translate=\"no\"\u003eUSER_PASSWORD\u003c/var\u003e: The password for the Datastream user that you want to create.\n2. Grant the following privileges to the user you created:\n\n ```\n GRANT RDS_REPLICATION TO USER_NAME;\n GRANT SELECT ON ALL TABLES IN SCHEMA SCHEMA_NAME TO USER_NAME;\n GRANT USAGE ON SCHEMA SCHEMA_NAME TO USER_NAME;\n ALTER DEFAULT PRIVILEGES IN SCHEMA SCHEMA_NAME\n GRANT SELECT ON TABLES TO USER_NAME;\n ```\n\n \u003cbr /\u003e\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eSCHEMA_NAME\u003c/var\u003e: The name of the schema to which you want to grant the privileges.\n - \u003cvar translate=\"no\"\u003eUSER_NAME\u003c/var\u003e: The user to whom you want to grant the privileges.\n\nWhat's next\n-----------\n\n- Learn more about how Datastream works with [PostgreSQL sources](/datastream/docs/sources-postgresql)."]]
