Subject [GitHub] accumulo issue #176: Wrote blog post about durability and performance
Date Mon, 31 Oct 2016 15:05:50 GMT
Github user keith-turner commented on the issue:

    https://github.com/apache/accumulo/pull/176
  
    > May want to point out https://issues.apache.org/jira/browse/HDFS-3702 as an option
starting with Hadoop 2.8, so that if the node goes down and can't be brought back up, you
can still recover using the WAL.
    
    @dlmarion what you are suggesting seems like it would require a lot of context to explain.
 I don't know how to write that context up.   I would be happy to add anything you write up
or you could write up a following blog post and I can review it.   I am thinking we can build
up a body of useful info and ideas w/ blog post, and blog post can reference other post to
avoid repeating contextual info.
    
    For the improvements sections I was also thinking of mentioning that another possible
solution to this would be to use the multiple tservers per node you added AND a custom balancer
that assigns tablets based on durability settings.  However I decided not add this information
because I though it would take too much to explain well.  This could also be another blog
post. I was not really sure what to do this idea... I couldn't even decided if it was a good
a idea or not.
