数据格式说明
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
您在使用数据传输同步源端数据至 Kafka、DataHub（Blob 类型）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 和 DefaultExtendColumnType。
Default JSON 消息格式
数据同步至 Kafka、DataHub（Blob 类型）和 RocketMQ 时，序列化方式 Default 使用如下 JSON 消息格式。
{
"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。包括 MYSQL/ORACLE/OCEANBASE（老模式，兼容使用）/OB_IN_ORACLE_MODE（老模式，兼容使用）/DB2（老模式，兼容使用）/OB_MYSQL/OB_ORACLE/DB2_LUW
"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", // SQL 变更表名
"db": "STRING", // SQL 变更库名。如果是 OceanBase 数据库，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：

{
"database": "STRING", // SQL 变更库名。如果是 OceanBase 数据库，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"

SharePlex JSON 消息格式
数据同步至 Kafka、DataHub（Blob 类型）和 RocketMQ 时，序列化方式 SharePlex 使用如下 JSON 消息格式。
{
"data": { // 变更数据键值对，如果是 INSERT / DELETE 是全量值，如果是 UPDETE 只有变更值
"col1": "val1"
},
"meta": {
"time": "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 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", // {变更库表名}-{主键值使用\u0001} 分割
"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
}
}

DefaultExtendColumnType JSON 消息格式
数据同步至 Kafka、DataHub（Blob 类型）和 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。
{
"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：

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。
