迁移服务 OMSV 4.0.0 社区版 # 数据格式说明 更新时间：2026-04-14 15:40:46 [编辑](https://github.com/oceanbase/oms-doc/edit/V4.0.0/zh-CN/700.data-synchronization/1600.data-formats.md) 本文为您介绍序列化方式和数据库传输到文本协议的数据格式。 ## 序列化方式的格式说明 您在使用 OceanBase 迁移服务（OceanBase Migration Service，OMS）社区版同步源端数据至 Kafka 和 RocketMQ 时，支持序列化方式控制数据同步至目标端的消息格式。序列化方式包括 **Default**、**Canal**、 **Dataworks**（支持 2.0 版本）、**SharePlex**、**DefaultExtendColumnType** 和 **Debezium**。 ### Default JSON 消息格式 数据同步至 Kafka 和 RocketMQ 时，序列化方式 Default 使用如下 JSON 消息格式。 ```json { "prevStruct": { // 变更前镜像 "col1": "val1" // 键值对，包含全量键值 }, "postStruct": { // 变更后镜像 "col1": "val1" // 键值对，包含全量键值 }, "allMetaData" { "checkpoint": "STRING", // 当前同步位点，增量阶段表示同步到的时间位点（秒级时间戳），全量阶段使用主键键值对表示 "record_primary_key": "STRING", // 主键列的名称。如果存在多列使用 \u0001 分割 "record_primary_value" "STRING", // 主键值。如果存在多列使用 \u0001 分割 "source_identity": "STRING", // 源端标识。如果是增量则是 subtopic，如果是全量则没有意义的序号 "dbType": "STRING", // 数据库的类型。 "storeDataSequence": LONG, // 该字段只有在增量场景下 source.json 配置中包含 sequenceEnabled=true 才存在，默认是 true。用于排序，生成规则是一个同步进程中，时间戳 + 不超过五位序号递增。 "table_name": "STRING", // 使用 SQL 语句进行变更的表的名称。 "db": "STRING", // 使用 SQL 语句进行变更的数据库的名称。如果是 OceanBase 社区版，则包含租户，格式为 {tenant}.{database}。 "timestamp": "STRING", // 数据变更秒级时间戳，仅增量存在 "uniqueId": "STRING", // 增量中表示 STORE 传递下来的事务序号标识 }, "recordType": "INSERT/UPDATE/DELETE/HEARTBEAT/DDL" // 变更类型 } ``` - DDL 的 Record 中，仅存在 "ddl" 为列名的键，值为 DDL 语句。 - 数据使用 JSON 表示： - prevStruct：表示增量数据的前镜像信息，即 SQL 执行前的数据。`DELETE` 或 `UPDATE` 存在前镜像。 - postStruct：表示增量数据的后镜像信息，即 SQL 执行后的数据。`INSERT` 或 `UPDATE` 存在后镜像。 - recordType：数据类型，包括 `INSERT`（插入）、`UPDATE`（更新）、`DELETE`（删除）、`ROW`（全量）和 `HEARTBEAT`（心跳消息）。 - allMetaData：消息的元信息。 - prevStruct 和 postStruct 的消息格式相同，均为 `列名: 值`。 数据示例如下： - INSERT（插入）数据的示例 ```json { "allMetaData":{ "checkpoint":null, "record_primary_key":"int8\u0001int16", "source_identity":null, "record_primary_value":"3\u0001129", "dbType":"OB_MYSQL", "table_name":"table_name", "db":"tenant.database", "timestamp":"1609344671" }, "prevStruct":null, "recordType":"INSERT", "postStruct":{

### Canal JSON 消息格式 数据同步至 Kafka 和 RocketMQ 时，序列化方式 Canal 使用如下 JSON 消息格式。 ```json { "database": "STRING", // 使用 SQL 语句进行变更的数据库的名称。如果是 OceanBase 社区版，仅存在数据库名称，无需租户名称。 "sqlType": { "col1": INTEGER, // 变更列类型，数字参考 java.sql.Types。 }, "data": [ // 变更后数据键值对，目前只会存在一条消息。 { "col1": "val1" } ], "pkNames": [ // 主键列名。 "col1" ], "old": [ // 仅 UPDATE 消息存在。表示 UPDATE 语句变更的列，即变更前的列值。 { "col1": "val1" } ],

"YYYY-MM-DDTHH:mm:ss", // 变更时间。 "op": "", // 变更类型，包括 ins/upd/del。 "posttime": "YYYY-MM-DDTHH:mm:ss", // 写入目标端的时间。 "idx":"STRING", //消息在事务中的索引/索引的消息数量。目前 OMS 社区版不统计事务总数，所以该参数无效。 "size": NUMBER, //事务内消息数量。该参数已废弃。 "seq": "STRING", // 排序序号，需要配合源端打开 transactionEnabled 才能存在。 "table": "STRING", // SQL 变更库表名 {database}.{table}。 "rowid": "STRING", // {变更库名.表名}-{主键值}。如果主键存在多列，则使用 \u0001 分隔。 "trans": "STRING", // 事务 ID。 "scn": "STRING", // 该字段只有在增量场景下 source.json 配置中包含 sequenceEnabled=true 才存在，默认是 true。用于排序，生成规则是一个同步进程中，时间戳 + 不超过五位序号递增。 }, "key": { // 仅 UPDATE 存在，表示变更前的值。 } } ``` 数据示例如下： ```json {

RocketMQ 时，序列化方式 DefaultExtendColumnType 使用如下 JSON 消息格式。 DefaultExtendColumnType JSON 消息格式会在 `DEFAULT` 的基础上，在镜像内增加一个字段 `__light_type`，用于表示字段的数据类型。 ```json { "prevStruct": { // 变更前镜像 }, "postStruct": { // 变更后镜像 "__light_type": { "col":{ // 字段的名称 "schemaType":"type" // 值的类型 } } }, "allMetaData" {}, } ``` 数据示例如下： ```json { "allMetaData":{ "checkpoint":null, "record_primary_key":"int8\u0001int16",

**DefaultExtendColumnType**，OceanBase 社区版对应的映射说明如下。 | 数据类型 | 映射类型 | 描述 | | --- | --- | --- | | TINYINT SMALLINT MEDIUMINT INT/INTEGER YEAR BOOL/BOOLEAN | Long | 64 位以下的整型。 正常数值，例如 1000，不使用科学计数法。 对于 BOOL/BOOLEAN，则 true = 1，false = 0。 | | DECIMAL NUMERIC | BigDecimal | 精确小数数值类型以及超过 64 位的整型。 对于整型数值不会展示小数点及小数。 对于存在小数的数值，会根据数据库传入的数据进行位数展示，不会去除末尾的 0，使用科学计数法。 | | FLOAT DOUBLE | Double | 浮点数 根据源端是 FLOAT 或 DOUBLE 类型决定有效位数。FLOAT 是 7 位有效位数，DOUBLE 是 16 位有效位数。 | | CHAR VARCHAR TINYTEXT TEXT MEDIUMTEXT LONGTEXT ENUM SET | String | 字符串 | | TINYBLOB BLOB MEDIUMBLOB LONGBLOB BINARY VARBINARY BIT | Bytes | 字节数组 默认以 BASE64 编码展示。 | | DATE | Date | 日期类型，格式为 `YYYY-MM-DD`。如果是非法时间，会显示原有字符串。 | | TIME | Time | 时间类型，格式为 `HH:mm:ss[.nnnnnnnnn]`。 低于秒级的时间最多展示 9 位。如果是低于秒级的时间，会显示出所有非 0 的数值。如果是非法时间，会显示原有字符串。 | | DATETIME | DateTime | 日期时间类型，包括时区。格式为 `YYYY-MM-DD HH:mm:ss[.nnnnnnnnn] [zoneId]`。 低于秒级的时间最多展示 9 位。如果是低于秒级的时间，会显示出所有非 0 的数值。如果是非法时间，会显示原有字符串。 | | TIMESTAMP | Timestamp | 时间戳类型，格式为 `[秒级时间戳][.nnnnnnnnn]`。 低于秒级的时间最多展示 9 位。如果是低于秒级的时间，会显示出所有非 0 的数值。如果是非法时间，会以 `0000-00-00 00:00:00` 格式显示。 | OMS 社区版 3.3.0-CE 及以上版本新建项目相较于 3.3.0-CE 以下版本的变更： > **说明：** > > > > OMS 社区版 3.3.0-CE 以下版本创建的项目升级至 3.3.0-CE 版本后，会维持之前的行为，不发生变更。 - OceanBase 社区版的 BIT 类型由之前的映射为 LONG 类型转换为 base64 编码的 bytes 值。通过 base64 解码后，能够得到相同结果。 - OceanBase 社区版的 Timestamp 类型以 `sec.mill` 格式传递，OMS 社区版 3.3.0-CE 以下版本以 `sec` 的整数格式传递。 - 其它时间类型格式为 `YYYY-MM-DD HH:mm:ss[.nnnnnnnnn]`，OMS 社区版 3.3.0-CE 以下版本的格式为 `YYYY-MM-DDTHH:mm[:ss]`。 - 如果序列化方式为 **Debezium**，OceanBase 社区版对应的映射说明如下。 | 数据类型 | 文字类型 | 描述 | | --- | --- | --- | | BOOLEAN BOOL | BOOLEAN | 取值包括 true 和 false。 | | TINYINT SMALLINT MEDIUMINT INT/INTEGER BIGINT YEAR | LONG | -2^63^ ～ 2^63^范围的整型。 | | BIGINT | STRING | 使用字符串完整展示数据。 | | FLOAT DOUBLE | DOUBLE | 浮点数。 | | DECIMAL NUMERIC | STRING | 使用字符串完整展示数据。对于存在小数的数值，会根据数据库传入的数据进行位数展示，不会去除末尾的 0，使用科学计数法。 | | BIT BINARY VARBINARY TINYBLOB BLOB MEDIUMBLOB LONGBLOB | BYTES | 字节数组，base16 编码。 | | CHAR VARCHAR TINYTEXT TEXT MEDIUMTEXT LONGTEXT ENUM SET | STRING | 字符串。 | | TIMESTAMP | STRING | 格式为 YYYY-MM-DDTHH:mm:ss[.nnnnnnnnn]Z，时区为 0 时区。 | | DATE | LONG | 表示自 1970-01-01 以来的天数。 | | TIME | LONG | 表示自 00:00:00 以来的时间值（以微秒为单位），不包括时区信息。 | | DATETIME | LONG | 表示自 1970-01-01 00:00:00 以来的毫秒数，不包括时区信息。 | 上一篇 下一篇
