Hi there, We have few clusters in AWS world and being forced to bump cluster version.
So, we are considering options to be in safer way possible, mitigating risks, and without outage as possible (our business is 24/7). Upgrade would be from 2.2.1 / 2.6.2 to 3.7.0 (MSK recommended version). Things to consider: * Recommended configurations in place so rolling restart is not impacting producers/consumers * Clients from different technologies (Java official client/Java SpringBoot Spring Cloud Stream/Alpakka Scala/NodeJS) around those versions * 2.2.1 cluster version -> TLS SSL SASL/SCRAM authenticated * 2.2.6 cluster version -> unathenticated * We don’t use Kafka streams Could you please which would be your recommendation in terms of upgrade brokers? Can be done directly or in several steps? We should upgrade clients before than brokers? If so, in which way? Client side, any recommendation of clients? (example: we use NodeJs rdkafka and looking could be limited to brokers 2.3.0, so probably we will need to jump into another client) Thanks [Logo, company name Description automatically generated] Jose Manuel Vega Monroy Software Engineer Team Leader Direct: +350 Mobile: +34(0) 633710634 WHG (International) Ltd | 6/1 Waterport Place | Gibraltar | Confidentiality notice: This email message and its attachments are for the sole use of the intended recipient(s) and may not be shared with any other party.
