Pulsar and Tiered Storage -- Any difference in functionality?

[Adam Brenner via users]

Hi!

When we configure Pulsar to tier data (segments from Bookkeeper) at the 
namespace or topic level does this change any of the functionality 
Pulsar offers -- example: Pulsar SQL (Trino) is able to search both data 
in bookkeeper and that in tiered storage?

I understand that reading data from tiered storage might be slower 
(object storage, NFS, etc.) compared to a bookkeeper cluster but wonder 
what, if any, functionality is gained or/and lost when data is tiered.

Thanks,
