| digvijay2016 | is it possible to get this patch merge into Newton release or only security fixes are going in it now? | 12:44 |

| zhongjun | tbarron: In usage size tracking spec. Do you mean we could add a common library method to let driver read/write data in memcatched? such as: driver private data. https://github.com/openstack/manila/blob/master/manila/share/drivers_private_data.py | 14:34 |
| tbarron | zhongjun: it's just a brainstorm at this point | 14:34 |
| tbarron | zhongjun: but now that you aren't using the database, we don't *necessarily* have to be bound by the rules for manager and driver w.r.t. database updates | 14:35 |
| tbarron | zhongjun: if we namespaced the memcached space so that each backend has its own sub-space | 14:35 |
| tbarron | zhongjun: then maybe the backend could do updates directly rather than the manager having to wait for the driver to | 14:36 |
| tbarron | zhongjun: return a big dictionary of share id - usage pairs | 14:36 |
| tbarron | zhongjun: so if some backends take a lot of time to collect the usage info and update | 14:37 |
| tbarron | zhongjun: the manager doesn't have to sit there waiting for them to return the info | 14:37 |
| tbarron | zhongjun: as you know, my main worry about the usage collection is how to scale it and have it perform well | 14:37 |
| tbarron | zhongjun: and I'd like us to think "out of the box" a bit about whether a different design pattern than what we use when | 14:39 |
| tbarron | manager calls into driver and stores update in database makes sense. | 14:40 |
| tbarron | so it's not really driver private data either, that's data private to the backend, but we still use the old pattern b/c that info goes to the database. | 14:40 |
| zhongjun | tbarron:yeh, if we want to let driver update usage size directly, then we could also consider about whether the driver solve too much things in driver, it could also have perform problem | 14:45 |
| tbarron | zhongjun: I don't know much about memcached, is writing a key-value there performance intensive? I was thinking of it basically as an in-memory write ... | 14:49 |
| *** digvijay2016 has quit IRC | 14:51 | |
| *** a-pugachev has quit IRC | 14:53 | |
| zhongjun | tbarron: yes, it basically as an in-memory write. ok, if we let driver update usage size directly, it could increase a little bit time in driver. | 14:58 |

| *** markstur has joined #openstack-manila | 15:07 | |
| tbarron | zhongjun: we have a manager (linux) process per backend, and the driver runs in that process too | 15:08 |
| tbarron | zhongjun: but they are async-threaded | 15:08 |
| *** rraja has quit IRC | 15:09 | |
| tbarron | zhongjun: so it may depend on whether the manager can do useful work that it wouldn't otherwise be able to do if it had to wait for the driver to collect all that info and return it to it, and the manager then has to write the results to memcached. | 15:09 |
| *** catintheroof has quit IRC | 15:10 | |
| tbarron | zhongjun: as I say, it's the synchronous call-and-wait into a driver who then has to spend time that scales with the number of shares it handles that concerns me | 15:10 |
