RE: Erasure Code Plugins : PLUGINS_V3 feature
Hi Loic, Thank you for arranging PLUGINS_V3 feature. I had just started to review pull request #5493. Please wait just a moment. By the way, may I ask what kind of status #5257 (decoding cache: the last immediate request from SHEC) currently is? https://github.com/ceph/ceph/pull/5257 Tell us if we need to rebase again.
