> 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.
