Incremental snapshot is a new mechanism to read snapshot of a table. Compared
to the old snapshot mechanism,the incremental snapshot has many advantages,

-| scan.incremental.snapshot.enabled | optional | true | Boolean |
增量快照是一种读取表快照的新机制。与旧的快照机制相比， 增量快照有很多优点，包括： (1) 快照读取时 Source 可以并行， (2) Source
可以在快照读取时在 Chunk 粒度上进行检查点， (3) Source 在读快照前不需要获取全局读锁（FLUSH TABLES WITH READ
LOCK）。 如果您希望源代码并行运行，每个并行阅读器都应该有一个唯一的服务器 ID，所以 'server-id' 必须是 '5400-6400'
这样的范围，并且范围必须大于并行度。

描述
|
+|------------------------------------------|----------|---------|----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| connector | required | (none) | String |
指定要使用的连接器，这里应该是 `'mysql-cdc-inlong'`。
|
+| hostname | required | (none) | String |
MySQL 数据库服务器的 IP 地址或主机名。
|
+| username | required | (none) | String |
连接到 MySQL 数据库服务器时要使用的 MySQL 用户名称。
|
+| password | required | (none) | String |
连接到 MySQL 数据库服务器时使用的密码。
|
+| database-name | required | (none) | String |
要监控的 MySQL 服务器的数据库名称。 database-name 还支持正则表达式来监控多个表是否匹配正则表达式。
|
+| table-name | required | (none) | String |
要监控的 MySQL 数据库的表名。 table-name 还支持正则表达式来监控多个表是否匹配正则表达式。格式为
database-name.table-name
|
+| port | optional | 3306 | Integer |
MySQL 数据库服务器的整数端口号。
|
+| server-id | optional | (none) | Integer |
此数据库客户端的数字 Id 或数字 Id 范围，数字 Id 语法类似于 '5400'， 数字 Id 范围语法类似于 '5400-5408'，启用
'scan.incremental.snapshot.enabled' 时建议使用数字 Id 范围语法。 在 MySQL
集群中所有当前运行的数据库进程中，每个 Id 都必须是唯一的。此连接器加入 MySQL 集群 作为另一台服务器（具有此唯一 Id），因此它可以读取
Binlog。默认情况下，会生成一个介于 5400 和 6400 之间的随机数， 尽管我们建议设置一个明确的值。
|
+| scan.incremental.snapshot.enabled | optional | true | Boolean |
增量快照是一种读取表快照的新机制。与旧的快照机制相比， 增量快照有很多优点，包括： (1) 快照读取时 Source 可以并行， (2) Source
可以在快照读取时在 Chunk 粒度上进行检查点， (3) Source 在读快照前不需要获取全局读锁（FLUSH TABLES WITH READ
LOCK）。 如果您希望源代码并行运行，每个并行阅读器都应该有一个唯一的服务器 ID，所以 'server-id' 必须是 '5400-6400'
这样的范围，并且范围必须大于并行度。
请参阅[增量快照阅读](https://ververica.github.io/flink-cdc-connectors/release-2.2/content/connectors/mysql-cdc.html#incremental-snapshot-reading)部分了解更多详细信息。
|
+| scan.incremental.snapshot.chunk.size | optional | 8096 | Integer |
表快照的块大小（行数），读取表的快照时，表的快照被分成多个块。
|
+| scan.snapshot.fetch.size | optional | 1024 | Integer |
读取表快照时每次轮询的最大获取大小。
|
+| scan.startup.mode | optional | initial | String |
MySQL CDC 消费者的可选启动模式，有效枚举为 'initial' 和 'latest-offset'。
请参阅[启动阅读位置](#启动模式)部分了解更多详细信息。
|
+| scan.startup.specific-offset.file | optional | (none) | String | 在
'specific-offset' 启动模式下，启动位点的 binlog 文件名。
|
+| scan.startup.specific-offset.pos | optional | (none) | Long | 在
'specific-offset' 启动模式下，启动位点的 binlog 文件位置。
|
+| scan.startup.specific-offset.gtid-set | optional | (none) | String | 在
'specific-offset' 启动模式下，启动位点的 GTID 集合。
|
+| scan.startup.specific-offset.skip-events | optional | (none) | Long |
在指定的启动位点后需要跳过的事件数量。
|
+| scan.startup.specific-offset.skip-rows | optional | (none) | Long |
在指定的启动位点后需要跳过的数据行数量。
|
+| server-time-zone | optional | UTC | String |
数据库服务器中的会话时区，例如 'Asia/Shanghai'。 它控制 MYSQL 中的 TIMESTAMP 类型如何转换为 STRING。
查看更多[这里](https://debezium.io/documentation/reference/1.5/connectors/mysql.html#mysql-temporal-types)。
|
+| debezium.min.row. count.to.stream.result | optional | 1000 | Integer |
在快照操作期间，连接器将查询每个包含的表，以便为该表中的所有行生成读取事件。此参数确定 MySQL
连接是否会将表的所有结果拉入内存（速度很快但需要大量内存），或者是否将结果改为流式传输（可能较慢，但适用于非常大的表）。该值指定在连接器流式传输结果之前表必须包含的最小行数，默认为
1,000。将此参数设置为'0'以跳过所有表大小检查并始终在快照期间流式传输所有结果。
|
+| connect.timeout | optional | 30s | Duration |
连接器在尝试连接到 MySQL 数据库服务器后在超时之前应等待的最长时间。
|
+| connect.max-retries | optional | 3 | Integer |
连接器应重试以建立 MySQL 数据库服务器连接的最大重试次数。
|
+| connection.pool.size | optional | 20 | Integer |
连接池大小。
|
+| jdbc.properties.* | optional | 20 | String |
传递自定义 JDBC URL 属性的选项。用户可以传递自定义属性，例如 'jdbc.properties.useSSL' = 'false'。
|
+| heartbeat.interval | optional | 30s | Duration |
发送心跳事件的时间间隔，用于跟踪最新可用的 Binlog 偏移量。
|
+| append-mode | optional | false | Boolean |
是否仅支持 Append，如果为 'true'，MySQL Extract Node 会将所有 Upsert 流转换为 Append 流，以支持不支持
Upsert 流的下游场景。
|
+| migrate-all | optional | false | Boolean |
是否是全库迁移场景，如果为 'true'，MySQL Extract Node 则将表的物理字段和其他元字段压缩成 'json' 格式的特殊 'data'
元字段, 目前支持两种 data 格式, 如果需要 'canal json' 格式的数据， 则使用 'data\_canal' 元数据字段，如果需要使用
