描述
Enhancement
currently we only let progress forward when KV is written to TiKV. When fast reorg is enabled, data will be batched on disk for a long time. No progress will be made during that stage and some users may suspect DDL is stuck.
So I propose we draw another line in metrics, which means "how many record KV we have read to assume the index KV".
