backport EC fast reads
Last modified: 2017-07-30 11:12:09 EDT
Backport EC fast read feature from Yahoo to hammer/1.3.x:
This optionally lowers the latency on reads from an EC pool at the expense of a bit of extra wasted IO and CPU by reading from all shards and decoding once K out of K+M replies come back.
It looks like this was fixed in some version of Hammer but I can't tell which version.
This hasn't been backported to hammer. I don't really think it's a good idea.
Thanks Sam. Looks like the feature is in Jewel so users can upgrade to RHCS 2 for this.
