ledger close and open
I want to use a ledger kind of like a queue, with writers appending at
one end and multiple readers retrieving at the other end,
does the writer have to close the ledger before readers start to read it?
furthermore, if the writer opens again the same ledger which was
closed before, is it OK?
Thanks a lot
Yang

Sounds like you need a pub-sub system. Hedwig is built on top of
bookkeeper to address this exact use case.
