Motivation

Although we has coverd most of standard metrics defined in FLIP-33: Standardize Connector Metrics, we still miss the metrics of pendingRecords which help us to trace data backlog.

Solution

pending records = latest log offset - fetched log offset.

For snapshot read phase of primary key table, it should be total records in kv snapshot - records emited, but to simplify, we can just trace the phase of incremental reading which read from change log.

Anything else?
