@pointearth @sijie How do you imagine the index composition regarding ledgers? As the first implementation, regarding pub/sub system, timestamp index-based would be a good start. I think we should first be able to auto-create an index per topic like: ```java Map[Date, LedgerId] ``` Or maybe ```java Map[Date, IndexItem] IndexItem(PreviousLedgerId, LedgerId, NextLedgerId) ``` WDYT? Maybe we should directly point to message and not ledger.
