Performance Impact with multiple Connector/Debezium perc schema to same MySQL database

Hi,
sorry to ask this question here but could find other way ...

If we have a large MySQL Database with multi-tenancy as each customer/user has a dedciated schema in the same MySQL. e.g. --> 20 users/cutomers = 20 schemas

For security, GDPR, seggregation we have implement (start with small number of connectors), 1 or 2 connectors to MySQL database (each connector as user/password and schema and list of tables that need to data be collected) but regarding the target of 20 or 60 users/customers is there any

• limitation of number of connectors?
• performance impact on MySQL ?
• issue/performance, on Kafka/Debezium with this approach ?

Regards,
Eric
