--------------------------------------------------
Summary: 128 bit LedgerId
Key: BOOKKEEPER-864
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-864
Project: Bookkeeper
Issue Type: Improvement
Reporter: Venkateswararao Jujjuri
BookKeeper coordinates with ZooKeeper to generate an cluster wide LedgerId.
This is a 64 bit number. This method works great because we have ZK acting as a
centralized coordinator. But this method may not scale as the cluster size and
number of ledgers increase.
GUIDs ( (https://en.wikipedia.org/wiki/Globally_unique_identifier) are
preferred way to generate decentralized globally unique IDs and it takes 128
bits ; This method can scale well as it doesn’t need a centralized
coordination.
Current BK code used ledgerId as a primary object, any change to this (64 to128
bit) warrants across the board code changes.
Opening this issue so we can solicit community input and track the progress.
