What did you do?

If a message is too large, both the Canal JSON and the Open Protocol encoders are logging the full message.

You can see the issue in 3 files:
canal_json_row_event_encoder.go:347
canal_json_tx_event_encoder.go:64
canal_json_row_event_encoder.go:69

What did you expect to see?

The message itself (the row data) should not be printed in logs as this is a PII violation

What did you see instead?

The content of the row
