<div style="font-size: medium; ">For all those that couldn't make it just wanted to share a summary of what happened. Thanks for showing up if you did :-)</div>

</div>
<div style="font-size: medium; ">TLDR:</div>
<div style="font-size: medium; "><br>
</div>
<div style="font-size: medium; ">- Taskflow library work continuing and progressing well.</div>
<div style="font-size: medium; "> - Database 'logbook' being added (thx jlucci) and looking great!</div>
<div style="font-size: medium; "> - Celery backend also progressing well (WIP)</div>
<div style="font-size: medium; "> - Stackforge move arriving soon!</div>
<div style="font-size: medium; ">- New potential use-cases</div>
<div style="font-size: medium; "> - Ironic via devananda has some potential use-cases for distributed locking to</div>
<div style="font-size: medium; "> ensure resources aren't 'modified' by multiple bare metal 'managers' at the</div>
<div style="font-size: medium; "> same time while allowing for multiple bare metal 'managers' to 'read' the </div>
<div style="font-size: medium; "> same resources.</div>
<div style="font-size: medium; ">- Lots of discussion on locking and the varying limitations that different locking </div>
<div style="font-size: medium; "> services/providers have and how it could fit the ironic use-case in a generic or</div>
<div style="font-size: medium; "> somewhat generic manner.</div>
<div style="font-size: medium; "> - Potentially discussion about using ZK, redis, memcache or a simpler </div>
<div style="font-size: medium; "> service+API to provide basic locking functionality. Each has its own</div>
<div style="font-size: medium; "> drawbacks and benefits and capabilities. (More ongoing discussion needed here!)</div>
<div style="font-size: medium; ">- Cinder being worked onto by yours truly to see how taskflow might apply there.</div>
<div style="font-size: medium; "><br>
</div>
<div style="font-size: medium; ">Takeaways:</div>
<div style="font-size: medium; "><br>
</div>
<div style="font-size: medium; ">- Need to explore how a locking 'service' can provide locks that fit a variety</div>
<div style="font-size: medium; "> of use-cases (where different backends may only provide some of those use-cases</div>
<div style="font-size: medium; "> while other backends may provide all of the use-cases).</div>
