flinkcdc 同步到doris,报这个错误,源表跟目标表结构是一样的,怎么处理?
遇到报错com.ververica.cdc.connectors.shaded.org.apache.kafka.connect.errors.DataException: file is not a valid field name,表明在同步过程中尝试访问的字段名file在实际的表结构中不存在。
解决方案建议:
核对字段名称:再次仔细对比源表和目标表的结构,确保字段名称完全一致,特别留意大小写差异。
检查同步配置:确认同步工具或作业的配置中没有错误地指定了字段名,包括任何正则表达式或通配符的使用,确保它们正确匹配了所有相关表的结构。
更新或调整同步工具:考虑升级至最新版本的同步工具或框架,如Ververica Platform 6.0.2及以上版本,这些新版本可能已经解决了类似问题,特别是对于分库分表场景的自动处理
日志分析:深入分析同步过程的日志,寻找有关字段映射或解析失败的具体信息,这有助于定位问题所在。
验证权限与设置:确认执行同步任务的用户具有足够的权限访问所有涉及的数据库和表,并检查是否已根据最佳实践设置了Debezium的相关参数,如debezium.inconsistent.schema.handling.mode[1],以更宽容的方式处理潜在的架构不一致问题。```js202x-xx-xx xx:xx:xx,xxx ERROR io.debezium.connector.mysql.BinlogReader [] - Encountered change event 'Event{header=EventHeaderV4{timestamp=xxx, eventType=TABLE_MAP, serverId=xxx, headerLength=xxx, dataLength=xxx, nextPosition=xxx, flags=xxx}, data=TableMapEventData{tableId=xxx, database='xxx', table='xxx', columnTypes=xxx, xxx..., columnMetadata=xxx,xxx..., columnNullability={xxx,xxx...}, eventMetadata=null}}' at offset {ts_sec=xxx, file=mysql-bin.xxx, pos=xxx, gtids=xxx, server_id=xxx, event=xxx} for table xxx.xxx whose schema isn't known to this connector.
