> On issue i could writing the tutorial is that when you open a ledger in
> non-recovery mode, it's not possible to check if the ledger you opened has
> been closed or is still been written too. This complicates things when you
> get to the end of the ledger, as you don't know whether to try for more
> entries in the same ledger, or to look at the next ledger is the list.
> This jira is to expose this information (it's in the metadata). This method
> only makes sense for reading. For writing a ledger, you really should know if
> you closed the ledger or not, and if you don't then you shouldn't be touching
> it again.
