[DISCUSS] KIP-1343: Allow opt-in leader-only acknowledgement in DeleteRecords

Hi team,

I would like to discuss KIP-1343: Allow opt-in leader-only acknowledgement
in DeleteRecords
to enable async deleteRecords RPC.

KIP:

Thanks,
TaiJuWu

Hi chia,

Thanks for your reply.

The core concern is that acks=0 (fire-and-forget) is meaningless for
DeleteRecords. Unlike Produce, where high-throughput writers can
reasonably trade acknowledgement for latency, DeleteRecords always
needs a response: the caller must know per-partition success/error and
the resulting offset to make any further decision.

I will update KIP for this section.

Best,
TaiJu

hi TaIju

Could you flesh out the motivation for using “LeaderOnly” instead of “acks”? We could use acks at the RPC level to maintain flexibility, while the Java APIs can remain strict on using a boolean.

Best,
