Deduplication on namespace level

[GmaD-X]

Hello everyone,
I was reading on the pulsar deduplication feature, specifically on the namespace level. On this I have a query and hope to get more clarity on this. Consider multiple producers, multiple topics and multiple consumers (for the sake of it lets say 1:1:1) under a common namespace with deduplication enabled. There maybe cases of the same event being publish to all the topics. I want only one copy of it persisted to memory, but every consumer should be able to consume the same event. Can deduplication help in this scenario? I am asking because I noticed that we are able to set the producerName and sequenceId per event and pulsar uses a combination of these two to achieve deduplication.

Thank you.
