Question

我正在尝试为我的SQL Server表创建源连接器，这是一个示例：

{
  "name": "test",
  "config": {
      "tasks.max":"1",
      "connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector",
      "connection.url": "jdbc:sqlserver://REDACTED;databaseName=REDACTED",
      "connection.user": "REDACTED",
      "connection.password": "REDACTED",
      "topic.prefix": "test",
      "poll.interval.ms" : 2000,
      "table.whitelist": "dbo.Client",
      "mode":"incrementing",
      "incrementing.column.name": "Id"
  }
}

我遇到以下错误，但什么也没说...

  java.lang.IllegalArgumentException: Number of groups must be positive.

当我将模式timestamp与timestamp.column.name（用datetimeoffset类型修改的列）一起使用时，也会发生同样的情况。

当我在自定义查询中使用模式批量时，效果很好。

有什么想法吗？

MSSQL不适用于放大或时间戳记源连接器
