[jira] [Commented] (HBASE-20951) Ratis LogService backed WALs

    [ https://issues.apache.org/jira/browse/HBASE-20951?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16630901#comment-16630901 ] 

Josh Elser commented on HBASE-20951:
------------------------------------

FYI HBASE-20952 was spun out into a standalone issue (from a child issue) to better support making small changes to the WAL API. Linked it off of this issue.

> Umbrella issue for the Ratis+WAL work:
> Design doc: [https://docs.google.com/document/d/1Su5py_T5Ytfh9RoTTX2s20KbSJwBHVxbO7ge5ORqbCk/edit#|https://docs.google.com/document/d/1Su5py_T5Ytfh9RoTTX2s20KbSJwBHVxbO7ge5ORqbCk/edit]
> The (over-simplified) goal is to re-think the current WAL APIs we have now, ensure that they are de-coupled from the notion of being backed by HDFS, swap the current implementations over to the new API, and then wire up the Ratis LogService to the new WAL API.
