   ```
    The implementation would become simpler, because it is a complex logic to handle and maintain slotmap in configured number of Entrylogs per LedgerDir design/implementation and it needs to be thoroughly analyzed/tested from multi-thread perspective. But most importantly the garbagecollection component becomes much simpler because there is no need of compaction in entrylog per ledger approach. So there is huge gain in indirect performance because of absence of IO activity for compaction and huge improvement in space reclamation during compaction.
   ```
   
   This needs to be clarified. It would have the benefits if you have small number of ledgers, I don't think it is good for large number of ledgers. It is good if you think from Salesforce's use case; however it is not, if you think from other use cases. This is good to be called out before you are claiming all the benefits here.
