[Reproduction Path] What operations were performed when the issue occurred
[Encountered Issue: Issue Phenomenon and Impact] I want to check what the large transaction was at a specific point in time in the production environment. When configuring Reparo, it keeps prompting [2023/12/18 11:32:53.518 +08:00] [ERROR] [main.go:67] [“reparo processing failed”] [error="new reader failed dir: /data/drainer-8249/data/: searchFiles failed: read binlog file name error: dir /data/drainer-8249/data/: binlogger: file not found.
Where is the binlog file stored? Which parameter configures it?

Your drainer needs to output the binlog as a file, which refers to the directory where these files are stored.

You need to enable binlog.
First, you need to install the pump component.
Then, you need the drainer to output the binlog to a local file.
Reparo reads the local file output by the binlog.

I feel that using reparo to check for large transactions is not a good method. It’s better to infer using BIG_TXN in the logs along with the SLOW LOG.

Yes, I found this transaction using this method as well, thank you~

There is an issue with the BILOG directory.

Enable pump, binlog drainer, and also have the relevant directories.
