In practice, you can also adjust the step to control the frequency of database updates. diff --git a/dm/dm-manage-schema.md b/dm/dm-manage-schema.md index 720d635eb3ca7..ed32f4acaafd7 100644 --- a/dm/dm-manage-schema.md +++ b/dm/dm-manage-schema.md @@ -124,7 +124,7 @@ binlog-schema list -s mysql-replica-01 task_single db_single t1 "sources": [ { "result": true, - "msg": "CREATE TABLE `t1` ( `c1` int(11) NOT NULL, `c2` int(11) DEFAULT NULL, PRIMARY KEY (`c1`)) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_bin", + "msg": "CREATE TABLE `t1` ( `c1` int NOT NULL, `c2` int DEFAULT NULL, PRIMARY KEY (`c1`)) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_bin", "source": "mysql-replica-01", "worker": "127.0.0.1:8262" } @@ -163,8 +163,8 @@ If you want to set the table schema of the ``` `db_single`.`t1` ``` table corres ```sql CREATE TABLE `t1` ( - `c1` int(11) NOT NULL, - `c2` bigint(11) DEFAULT NULL, + `c1` int NOT NULL, + `c2` bigint DEFAULT NULL, PRIMARY KEY (`c1`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_bin ``` diff --git a/dm/dm-open-api.md b/dm/dm-open-api.md index ada86e1cbf718..3ca2ea452b20d 100644 --- a/dm/dm-open-api.md +++ b/dm/dm-open-api.md @@ -1615,7 +1615,7 @@ curl -X 'GET' \ { "schema_name": "db1", "table_name": "table1", - "schema_create_sql": "CREATE TABLE `t1` (`id` int(11) NOT NULL AUTO_INCREMENT,PRIMARY KEY (`id`) /*T![clustered_index] CLUSTERED */) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin" + "schema_create_sql": "CREATE TABLE `t1` (`id` int NOT NULL AUTO_INCREMENT,PRIMARY KEY (`id`) /*T![clustered_index] CLUSTERED */) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin" } ``` @@ -1637,7 +1637,7 @@ curl -X 'PUT' \ -H 'accept: */*' \ -H 'Content-Type: application/json' \ -d '{ - "sql_content": "CREATE TABLE `t1` ( `c1` int(11) DEFAULT NULL, `c2` int(11) DEFAULT NULL, `c3` int(11) DEFAULT NULL) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;", + "sql_content": "CREATE TABLE `t1` ( `c1` int DEFAULT NULL, `c2` int DEFAULT NULL, `c3` int DEFAULT NULL) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;", "flush": true, "sync": true }' diff --git a/dm/dm-performance-test.md b/dm/dm-performance-test.md index 06a6bc4600df2..3429ef8c40a86 100644 --- a/dm/dm-performance-test.md +++ b/dm/dm-performance-test.md @@ -27,8 +27,8 @@ Use tables with the following schema for the performance test: ```sql CREATE TABLE `sbtest` ( - `id` int(11) NOT NULL AUTO_INCREMENT, - `k` int(11) NOT NULL DEFAULT '0', + `id` int NOT NULL AUTO_INCREMENT, + `k` int NOT NULL DEFAULT '0', `c` char(120) CHARSET utf8mb4 COLLATE utf8mb4_bin NOT NULL DEFAULT '', `pad` char(60) CHARSET utf8mb4 COLLATE utf8mb4_bin NOT NULL DEFAULT '', PRIMARY KEY (`id`), diff --git a/dm/dm-table-routing.md b/dm/dm-table-routing.md index 2625c6aaf1fb1..1950dd5d77e19 100644 --- a/dm/dm-table-routing.md +++ b/dm/dm-table-routing.md @@ -116,7 +116,7 @@ To extract the source information of upstream sharded tables to the merged table ```sql CREATE TABLE `test`.`t` ( - a int(11) PRIMARY KEY, + a int PRIMARY KEY, c_table varchar(10) DEFAULT NULL, c_schema varchar(10) DEFAULT NULL, c_source varchar(10) DEFAULT NULL @@ -184,7 +184,7 @@ mysql> select * from test.t; ```sql CREATE TABLE `test`.`t` ( c_table varchar(10) DEFAULT NULL, - a int(11) PRIMARY KEY, + a int PRIMARY KEY, c_schema varchar(10) DEFAULT NULL, c_source varchar(10) DEFAULT NULL ); @@ -194,7 +194,7 @@ CREATE TABLE `test`.`t` ( ```sql CREATE TABLE `test`.`t` ( - a int(11) PRIMARY KEY, + a int PRIMARY KEY, c_table varchar(10) DEFAULT NULL, c_schema varchar(10) DEFAULT NULL, ); @@ -204,9 +204,9 @@ CREATE TABLE `test`.`t` ( ```sql CREATE TABLE `test`.`t` ( - a int(11) PRIMARY KEY, + a int PRIMARY KEY, c_table varchar(10) DEFAULT NULL, - c_schema int(11) DEFAULT NULL, + c_schema int DEFAULT NULL, c_source varchar(10) DEFAULT NULL, ); ``` diff --git a/dm/feature-online-ddl.md b/dm/feature-online-ddl.md index e853ef67ff688..adb01c0e15570 100644 --- a/dm/feature-online-ddl.md +++ b/dm/feature-online-ddl.md @@ -131,8 +131,8 @@ The SQL statements mostly used by pt-osc and the corresponding operation of DM a 1.
