Hi all,
I'd like to share a document that I've been working on for many months
with Jitendra about building a distributed-log "recipe" on top of Ratis.
https://docs.google.com/document/d/1Su5py_T5Ytfh9RoTTX2s20KbSJwBHVxbO7ge5ORqbCk/edit?usp=sharing
The primary use case is for Apache HBase, replacing its HDFS-backed
write-ahead log construct with something a bit more flexible. Our hope
is that by building a distributed log with Ratis, HBase could observe
similar levels of performance as we do with HDFS and better enable our
flexibility to run on "dynamic" cloud IaaS platforms.
At the bottom of that document, you'll find a high level breakdown of
work items for both Ratis as well as HBase. My hope is that both of
these will be able to be worked on concurrently. Furthermore, while
HBase is a primary "customer" for the work, I hope that you would find a
DistributedLog recipe for Ratis (what we've been calling the
"LogService") generally reusable for the Ratis community.
Please let me know what you think (either on the mailing list or via
comments on the google-doc). Thanks!
- Josh
