| Qiming | hi, miaohb | 11:52 |
| miaohb | hi,qiming | 11:53 |
| Qiming | when i was reviewing your patch #393983 | 11:53 |
| miaohb | can we speak Chinese, hehe | 11:53 |
| Qiming | I was feeling guilty because it was exactly a thing we killed half a year ago | 11:54 |
| Qiming | typing english is a little bit faster .... | 11:54 |
| miaohb | ok | 11:55 |
| Qiming | previously we had 'level', 'cooldown' defined for all policies | 11:56 |
| miaohb | You mean we need not to support priority now? | 11:56 |
| Qiming | back in Jan: http://git.openstack.org/cgit/openstack/senlin/commit/senlin/policies/base.py?id=5160d2f230afa1bd71c693857aa3c9b7aad058d6 | 11:56 |
| Qiming | senlin policy priority, as of today, is hardcoded | 11:56 |
| Qiming | it won't change no matter you attach it to which cluster | 11:57 |
| Qiming | because the policies have an implicit dependency among them | 11:57 |
| miaohb | but i think different policy can have different priority | 11:58 |
| Qiming | take scale-out operation as an example | 11:58 |
| Qiming | yes, they do have different priorities, but those priority cannot be changed freely | 11:58 |
| Qiming | back to the scale-out example, listen to my story please | 11:58 |
| Qiming | the first policy you will check is the scaling policy | 11:59 |
| miaohb | Ok | 11:59 |
| Qiming | that policy may change the number of nodes to create | 11:59 |
| Qiming | you can only make a good placement plan after you know for sure how many nodes you will create | 12:00 |
| Qiming | similarly, you cannot reliably evaluate the deletion policy without knowing how many nodes to remove | 12:00 |
| Qiming | so after a discussion, we decided to hard code the policy priorities | 12:02 |
| Qiming | see example here: http://git.openstack.org/cgit/openstack/senlin/tree/senlin/policies/scaling_policy.py#n34 | 12:02 |
| Qiming | when removing nodes from a cluster, for another example, the flow is always like this: | 12:03 |
| Qiming | 1) scaling policy decides the number of nodes to remove; 2) deletion policy decides the exact nodes as victims; 3) lb_policy to remove them from the load-balancer | 12:04 |
| Qiming | you cannot let the lb_policy have a higher priority than the scaling policy ... that will break the whole work flow | 12:05 |
| miaohb | yes | 12:07 |
| miaohb | May I speak? | 12:08 |
| miaohb | I drop again? | 12:10 |
| XueFeng | online | 12:11 |
| miaohb | Why we keep the priority | 12:13 |
| miaohb | In the cluster policy ? | 12:13 |

| Qiming | even in the cluster-policy binding, we have that field, we didn't meant to use it | 12:43 |
| XueFeng | It seems priority is hard code in each policy.And because policies have dependency work flow, we choice hard code before no good idea? | 12:44 |
| Qiming | yes | 12:44 |
| Qiming | we cannot expose priorities to users | 12:44 |
| XueFeng | Then because hard code, we will not show the priority to users? | 12:44 |
| Qiming | it may lead to any result | 12:45 |
| Qiming | right | 12:45 |
| Qiming | exposing that to users will lead to questions ... why cannot I change it? | 12:45 |
| Qiming | what does 200 mean? | 12:45 |
| XueFeng | it is | 12:47 |
| XueFeng | interrupt,can we save chat in #senlin such as #openstack-meeting. | 12:50 |
| miaohb | My patch is just to display ,user have no way to change the ita | 12:50 |
| miaohb | the vaue | 12:50 |
| Qiming | all chats are saved, all meetings are saved as well | 12:51 |
| Qiming | IRC logs can be found here: http://eavesdrop.openstack.org/irclogs/%23senlin/ | 12:51 |
| Qiming | weekly meetings are logged here: http://eavesdrop.openstack.org/meetings/senlin/2016/ | 12:52 |
| XueFeng | ok.I know #openstack-meeting logs before. | 12:52 |
| XueFeng | Not find #senlin log. Got it. | 12:53 |
| Qiming | it is shown as a prompt when you enters #senlin channel | 12:53 |
| Qiming | I mean this line: IRCLog: http://eavesdrop.openstack.org/irclogs/%23senlin/ | Bugs: bugs.launchpad.net/senlin | Review: https://review.openstack.org/#/q/project:openstack/senlin,n,z | 12:54 |
| XueFeng | I saw it. | 12:54 |
| XueFeng | Thanks:) | 12:54 |
| XueFeng | continue priority | 12:55 |
