Concurrency and multiple topics support

[srius]

Hi all,

I saw that concurrency in Kafka connector and multiple topics support have been added in releases 2.1.0 and 2.2.0 respectively (PR #329 and #658).
The first one is enabled with partitions attributes set accordingly to number of partitions. The second one can be activated with topic attribute as a regexp and pattern attribute set to true (or the topics attribute).
According the documentation

partitions	The number of partitions to be consumed concurrently. The connector creates the specified amount of Kafka consumers. It should match the number of partition of the targeted topic. Type: int	false	1

It is said "the targeted topic", singular. Shall I understand that concurrency is not compliant with multiple topics support, especially with regexp ? If compliant, will each instantiated Kafka consumer consume from all "pattern" targeted topics or each topic will have its own consumers instances ?

Best regards.
