----------------------------------
Hi [~jark]
Does this mean that each table corresponds to a Kafka connection? If I want to
reuse Kafka connections, are there any other good ideas?

> Usually, users use Canal to synchronize binlog data from various MySQL
> databases and tables into a single Kafka topic. However, currently,
> canal-json can't support this case, because it requires the canal data in the
> topic should be in the same data format.
> This issue propose to introduce a new option "canal-json.database" and
> "canal-json.table" to filter out the specific data. It would be great to
> support table list or table pattern in case of all the tables have the same
> schema.
