Hi all,
Here is a draft for BookKeeper Board report of Feb. Please take a look.
---------------------------------
## Description:
BookKeeper is a scalable, fault-tolerant, and low-latency storage
service optimized for append-only workloads. It has been used as
a fundamental service to build high available and replicated services
in companies like Twitter, Yahoo and Salesforce. It is also the log
segment store for Apache DistributedLog and message store for Apache Pulsar.
Apache DistributedLog is a high-level API and service layer for
Apache BookKeeper, providing easier access to the BookKeeper
primitives. It is a subproject of Apache BookKeeper.
