Hi, Bo. Do you means adding a logger sink after the actual sink? IMO, that is impossible.
But there is another way. If the sink is provided by flink, you can modify the code in it like adding a INFO-level log, print a clearer exception and so on. Then re-build the specific connector. -- Best! Xuyang 在 2023-11-04 17:37:55,"Bo" <99...@qq.com> 写道: Hi, Yu Thanks for the suggestion. Ideally the data need to come from the sink being audited, adding another sink serves part of the purpose, but if anything goes wrong in the original sink, I presume it won't be reflected in the additional sink. (correct me If I'm mistaken) I may have to make some custom sink based on the official ones ------------------ Original ------------------ From: Chen Yu <yuchen.e...@gmail.com> Date: Sat,Nov 4,2023 3:31 PM To: Bo <99...@qq.com>, user <user@flink.apache.org> Subject: Re: Auditing sink using table api Hi Bo, How about write the data to Print Connector[1] simultaneously via insertInto[2]? It will print the data into Taskmanager's Log. Of course, you can choose an appropriate connector according to your audit log storage.

By "auditing", I mean to log details of every row data coming into the sink, and any anormalies when the sink write to external systems. Does flink have some kind of auditing mechanism in place? The only way I could see now is to make a custom sink that supports detail logging to external systems. Any thoughts/suggestions? Regards, Bo
