Description

Now it's calculated based on the encoded kafka message. Not matched to the ticdc input bytes / s, this is not expected.

Research direction

Start at the Kafka sink's write-bytes-per-second metric calculation and trace whether it uses the encoded Kafka message or the raw entry corresponding to TiCDC input. Done means the metric is based on raw-entry bytes and matches TiCDC input bytes/s rather than encoded-message size.
