使用mysql-cdc 的scan.startup.mode = specific-offset的读

Hi all: 最近用mysql-cdc的方式，使用Flink-sql整合数据，table的部分配置如下 'debezium.min.row.count.to.stream.results'='1000', 'scan.startup.mode'='specific-offset', 'scan.startup.specific-offset.file'='mybinlog.000029', 'scan.startup.specific-offset.pos'='542607677' 在上述稳定运行接分钟之后，异常抛出了以下错误： org.apache.kafka.connect.errors.ConnectException: The connector is trying to read binlog starting at GTIDs 36b8bd0f-a435-11eb-9962-b4055d9ecb74:21820662-21926801,d713fc3c-afc6-11eb-a7b8-b4055d9ec5e6:185910-192349 and binlog file 'mybinlog.000029', pos=808323397, skipping 6 events plus 1 rows, but this is no longer available on the server.
