dhruba borthakur commented on ZOOKEEPER-465:
--------------------------------------------
Please pardon my ignorance, but your approach works because nobody can append
new entries to a ledger after it is closed, right?
Also, what will be the semantics of a concurrent reader? For example, if
process A is writing to a ledger while at the same time another process B wants
to find the length of the ledger, Is this possible?

> It is currently easy to know how many entries a ledger has, but there is no
> easy way to know the total number of bytes in a ledger. The idea of this jira
> is to add a method that gives the number of bytes in a closed ledger. My
> current idea is to simply have the writer counting the number of bytes
> written and store it to ZooKeeper.
