What problem does this PR solve?
Issue Number: close #xxx
Problem Summary:
We've tested the big transaction when binlog enabled, pump, and drainer can handle 10GB transactions. But with Kafka as an arbiter or some other usage of binlog, it could only handle 1GB transactions, because Kafka has its own max message limit.
What is changed and how it works?
Proposal: xxx
What's Changed:
We could not know if there is a Kafka cluster using in the binlog replication. So we remove the limitation and keep the warnings of txn-total-size-limit usage.
How it Works:
