*** romero_ has joined #openstack-infra | 15:40 | |
jeblair | clarkb, fungi, mordred: i'm thinking maybe nodepool should have a set number of launcher threads, and a set number of delete threads, and we use the producer/consumer model with them; that should make it easy to calculate the max # of connections, and put a cap on burstiness (for ourselves and our providers) | 15:42 |
Alex_Gaynor | that sounds relatively seen (if you're keen on threads); alternatively an event driven concurrency framework may also make sense | 15:43 |
jeblair | as it is, we can calculate the launch burstiness -- we'll never do more than 30 at a time; but on gate resets, we could have a huge number of completion events all at once | 15:44 |
jeblair | in our current configuration, almost 300 | 15:44 |
fungi | it makes sense to keep control of surges | 15:45 |
fungi | particularly since vm create/delete are extremely expensive operations and our providers may throttle them anyway | 15:46 |
clarkb | jeblair: we won't delete up to 300 nodes on a reset though. nodepool will just have to wade through that many events on the pub sub? | 15:46 |
jeblair | Alex_Gaynor: possibly so; have one in mind? | 15:47 |
clarkb | hmm nevermind I see what you are saying. if we delete all of our capacity at once that is 96 * 3 | 15:47 |
jeblair | yep | 15:47 |
Alex_Gaynor | jeblair: obviously eventlet is used by ~all of openstack, I'm stilla twisted fan though :) | 15:47 |

Alex_Gaynor | parts of twisted support python3 (this may literally be the worst answer ever :P) | 15:48 |

Alex_Gaynor | do you know the number off hand? | 15:50 |
fungi | Alex_Gaynor: http://twistedmatrix.com/trac/ticket/4212 | 15:51 |
fungi | Alex_Gaynor: it's a twisted ssl+ipv6 issue apparently | 15:51 |
jeblair | Alex_Gaynor: that bug is why meetbot becomes such a headache during netsplits; we have had to hardcode addresses in the /etc/hosts file on eavesdrop to deal with that | 15:52 |
clarkb | jeblair: I would be happy with tulip. That said there isn't anything wrong with threads here imo. This is actually what threads are useful for in python | 15:53 |

clarkb | maybe they are squatting? certainly confusing | 16:07 |
clarkb | ok I must go now if I am ever going to make it to portland at a reasonable time | 16:08 |
Alex_Gaynor | I think it's just some bad mixups, benoit's certainly not a bad actor | 16:08 |

mordred | jeblair: the nice thing about some of our things, like nodepool | 19:32 |
mordred | jeblair: is that they have one install that we care about (even if other people decide to re-use them) | 19:32 |
mordred | jeblair: so if we wanted to use python 3.4 - you know - great | 19:32 |

jeblair | mordred, fungi, clarkb: two possible interim solutions that i think improve upon the current state without major architectural changes: | 22:15 |
mordred | jeblair: yah? | 22:16 |
jeblair | a) set the pool size to be larger than the sum of max_servers because mysql connections (especially mostly idle ones) are cheap | 22:16 |
jeblair | we won't ever do more db operations than we can have servers, so that should be ok | 22:16 |
* mordred does not think we are ever going to stress the db :) | 22:17 | |
jeblair | b) tighten the session scoping around db calls so that whenever it needs to access the db, it checks out a conn, does db work, and returns it quickly with no other work done during that period | 22:17 |
jeblair | so each launch would have about 3 such sections where it does a bit of db access | 22:18 |
jeblair | mordred: i think in the forseable future, we'd have something like 600-1500 servers, max, so that would be the max pool size for (a) | 22:19 |
*** Ryan_Lane has joined #openstack-infra | 22:21 | |
jeblair | mordred: for that matter, why don't we just disable the size limit on the pool? :) | 22:24 |

mordred | looking | 22:33 |

fungi | mmm, will have a look in a little while, after we unpack and take a brief stroll | 23:42 |
fungi | ahh, i already looked at that'un i did | 23:44 |
jeblair | fungi: it's slightly modified | 23:45 |
fungi | -1 means unlimited? | 23:45 |
jeblair | ya | 23:45 |
fungi | oh, much better commit msg too | 23:45 |
clarkb | jeblair is the only change s/100/-1/? | 23:46 |
fungi | agreed, ~.1k connections on a vm that size is chump change | 23:46 |
clarkb | phone is not so good at pulling up gerrit changes, but I am fine with changing the burst limit | 23:47 |
jeblair | clarkb: i also added a thing that makes sure the session is returned to the pool on context mgr exit, and that the session can't be used again without starting a new context mgr | 23:48 |
jeblair | clarkb: no rush really; it's already running; it can wait to formally merge. | 23:48 |
clarkb | cool. will probably get to it monday then | 23:49 |
