events_cache topic needs to have a prefix (Kiwi HF#2)

Description

Overview:

The topic events_cache does not have a prefix. When a Kafka cluster is shared between different tenants, the topics are indistinguishable and can cause disastrous and unexpected results when the messages of one tenant is consumed by another tenant.  At the very least the topic should have the following prefix pattern: <env>.events_cache.

Note that this has been the design up to Kiwi.

Verified on kiwi bugfest - the events_cache topic has the env prefix kbf. Closing this ticket

Deployed to Kiwi BF. Please proceed with verification

Hi ,  ,

Story description has been updated to remove tenantId from new kafka cache topic name, since this parameter is not available at the moment of kafka-cache topic creating.

Hi All sounds good - I'll put this at the top of the Bug backlog. Then once it's released to Kiwi BF, we'll get DevOps to check

Hi , we cannot test it from user perspective, but we can ask DevOps to verify that events_cache topic has an appropriate prefix. The fix is not needed for Lotus, so yes - this ticket can be used for Kiwi HF. As for RCA category - I put an "Implementation coding issue", it might not be a 100% accurate, but the closest one. In any case, we didn't foresee that events_cache topic would create problems in case Kafka instance is shared. 

Done
