Alter client.dns.lookup in MSK connector

Question

I have an AWS MSK managed connector which seems to use this default configuration - client.dns.lookup = use_all_dns_ips

I'd like to change this value but when I try set client.dns.lookup in connector configurations it appears that it makes no difference. Could it be that it's not supported or am i specifying it incorrectly?

client.dns.lookup=resolve_canonical_bootstrap_servers_only

Thanks in advance,

Answer 1

I've since understood this is not possible. Custom worker configuration does not support this value, nor does it support producer.override.

Answer 2

You need to duplicate the value with a prefix of producer.override. and/or consumer.override. respectively for source/sink to alter client behavior within a connector.

Otherwise, you need access to modify the worker properties with that config.
