There was a problem hiding this comment.
Instead of adding "VisibleForTesting" annotation here, please extract this logic to a separate class which is tested separately. There's a lot of complexity here and this would be very hard to maintain in the future in this form. Smaller classes and smaller methods are a general preference in maintainable code.

Motivation
Broker serialize
individualDeletedMessagesas an array(1:1..1:5000],(2:-1..3:5000],,(100:-1..100:5000], each ledger will have a separate record, even if multiple ledgers are contiguous.We can compress the contiguous records to one, such as
(1:1...100:5000]. This can make one entry maintain more data.Modifications
Compress the contiguous records to one to make one entry maintain more data.
Next to do: push another PR to compress the response of
pulsar-admin topics stats.In what cases would it be useful
