@wuchong I have added a IT case in `KafkaChangelogTableITCase` to test
Kafka and Canal JSON with metadata accessing.
About the Canal JSON metadata, I prefer to the following keys and types:
- `database STRING`
- `table STRING`
- `sql-type MAP<STRING, INT>`
- `pk-names ARRAY<STRING>`
- `ingestion-timestamp TIMESTAMP(3) WITH LOCAL TIME ZONE`
The name of keys are a little different from yours. What do you think about
the above names of keys?
