Subject [GitHub] accumulo issue #176: Wrote blog post about durability and performance
Date Mon, 31 Oct 2016 15:05:50 GMT

    > May want to point out 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.
