A solution to query Pulsar backlog

[jbarotin]

Hi,

We are looking for a solution to query the pulsar backlog, the idea is to do that often and programatically.

I'm aware of pulsar-sql based on presto, but it's a bit heavy and It seems not really maintenained.

Are there any solutions, maybe to query directly Bookkeeper while taking into account the Pulsar Data model and subscriptions cursors ?
