How Mysql connector ensure sequences in distributed mode

Hi folks

I  am trying to find documents that explain how Mysql Connector ensure the sequences in distributed mode, but unluckily that I have found it yet.

So I have some questions regarding the Mysql Connector in distributed mode.

Assuming we have 3 mysql connectors in distributed mode. So:

1. How many connectors reading the mysql binlog at a time. Is it only one?
2. What kind of tasks are distributed to connectors/nodes in distributed mode?
3. If we have 2 updates to the record with id 1001 in table1, then how we ensure that these two messages will go to one Kafka topic partition with correct sequences (update1 first, then update2)
