Add query executed user information to Mysql binlog

Question

We are using MYSQL as our production database and we have setup another salve for read requests. Time to time various database users can execute insert/update queries on master database. If we want identify those executed queries (auditing/troubleshooting) we are using mysql bingos for it (reading after decoding it). From mysql binlog we can identify the query but we cant identify the executed user. is their a way to get that query executed user info into binlog. Enable general log wont be a option due to performance issues.

Answer 1

Not sure about general log, but this behavior belongs to auditing system. If you don't insist to write into binlog, both Oracle and Percona offer solutions:
