It does :) That was why I asking. The times I evaluated Pulsar (and thus BookKeeper) I found myself unconvinced of BK's reliability, just because of wrong docs, comments in the user facing code that were wrong etc.

But I never used it for real, with real data volume and throughput, so maybe the actual implementation was solid. The concepts in BK definitely made a lot of sense.

You need bear in mind that Pulsar is the FOSS version of Twitter's homebrewed PubSub, with the same people leading it now (Streamnative) who led it in Twitter.

And Twitter replaced it with Kafka. Which added to my caution.

So yeah, thought I'd ask if they'd evaluated BK, because it's relevant to the reliability of Pulsar.

If BK is ZK levels of solid, then that's awesome.
