Sijie Guo created BOOKKEEPER-571:
------------------------------------

             Summary: Change ledgers based on total size rather than number of messages.
                 Key: BOOKKEEPER-571
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-571
             Project: Bookkeeper
          Issue Type: New Feature
            Reporter: Sijie Guo
             Fix For: 4.3.0


currently hedwig changes ledger based on the number of messages had for each ledger. it would be better that changing ledger could be based on the total size of messages a ledger had. size is a better unit for resource estimation.

future more, the change ledger behaviors could be abstracted as a LedgerChangePolicy and could be customized.
