Rakesh R commented on BOOKKEEPER-773:
-------------------------------------
bq.you pulled all ledgers into a list, which doesn't work if your cluster have
a lot of ledgers.
Actually I pulled all the ledgers to find the total number of ledgers. Is there
any single API to know the total number of ledgers, otw I've to first iterate
over all the ledgers and get the total count. Then secondly will get the
iterator again and then iterate over all the ledgers asynchronously(as I
mentioned earlier will have bandwidth in place to control the concurrency).
If I understood correctly you are suggesting to go with one-by-one ledger
rename (sequential execution). FYI - Initially I done the same way, but

to make it concurrent and I also felt it would be useful one.
bq. one is using your current solution, while the other one is using ledger
iterator. so people could choose what to use. although I don't suggest to have
two implementation on this, it would make code maintenance become hard.
I also prefer to implement one good solution. Both are not required.
