Mahadev konar updated ZOOKEEPER-380:
------------------------------------
Attachment: ZOOKEEPER-380.patch
I am attaching a patch which changes the current bookkeeper api to move all the
reading and writing to ledgerhandle rather than using BooKKeeper api. The
BooKKeeper api acts like a bookkeeper handle which can be used to create/open
ledgers. THe reading and writing can then be done using ledgerhandle api.
I havent yet finished my streaming api. I wnated to make some changes to the
bookkeeper api so that it easier to use and can be extended to write a
streaming interface on the ledgerhandle.
comments?
> bookkeeper should have a streaming api so that its easier to store
> checpoints/snapshots in bookkeeper.

>
> currently, bookkeeper api allows just a bytes interface which is
> ld.write(bytes).
> We should have an interface like
> Stream s = ledger.createStream() (I am not very sure of the interface right
> now but will post a more concrete one after giving it a little more thought)
> now this stream can be used to wirte checkpoints as
> s.write(bytes)
> and then closed to s.close() to close the snapshot.
> This api could use the current api to implement snapshots as chunks of bytes
> (buffered by stream s) that can be written via ld.write(bytes).
