   I am affected by this also - we're trying to reclaim disk for two reasons
   1) Security / customer requirements to NOT retain data
   2) Cost
   
   What I have done so far inspired by @addisonj 
   i) Lowered `majorCompactionInterval` from 86400 (1 day) to 7200 (2 hours)
   ii) Lowered `managedLedgerMaxLedgerRolloverTimeMinutes` from 240 (4 hours) 
to 90 (1.5 hours)
   
   Open question on whether I should change `majorCompactionThreshold` from the 
(Pulsar) default of 0.5 as I don't fully understand if lower values mean more 
or less disk space usage. 
   
   Thanks in advance
