| kota_ | hello, takashi | 02:06 |
| kota_ | it looks like a bunch of conversations in the yesterday meeting. great. | 02:06 |
| kota_ | takashi: I'm wondering we could consider to use splice that swift can also do zero copy GET from fd into network socket. | 02:08 |
| kota_ | the reference is 7d0e5ebe690bf3cf41ccd970281d532a23284e58 | 02:08 |
| kota_ | ah, https://github.com/openstack/swift/commit/7d0e5ebe690bf3cf41ccd970281d532a23284e58 | 02:09 |
| kota_ | Sam worked on that for enabling it avoiding the copy from kernel space to user space when GET object requested. | 02:10 |
| kota_ | it might be helpful you understand how it works. | 02:10 |

| takashi | eranrom: I submitted a patch 327244 to revive zero copy in get. plz have a look if you have time | 02:44 |
| patchbot | takashi: https://review.openstack.org/#/c/327244/ - storlets - Revive zero-copy about GET execution on object-server | 02:44 |
| takashi | that patch depends on some existing refactoring. If you mind removing zero copy temporaly when we only merge dependencies, I'm going to squash them into one. | 02:46 |
| takashi | the following is the dependency chain for protocol refactoring. (Base) patch 314140 -> patch 325553 -> patch 324663 -> patch 327244 | 02:49 |
| patchbot | takashi: https://review.openstack.org/#/c/314140/ - storlets - Refactor Storlet protocol classes | 02:49 |
| patchbot | takashi: https://review.openstack.org/#/c/325553/ - storlets - Improve handling of fds in StorletInvocationProtocol | 02:49 |
| patchbot | takashi: https://review.openstack.org/#/c/324663/ - storlets - Merge StorletRequest classes | 02:49 |
| patchbot | takashi: https://review.openstack.org/#/c/327244/ - storlets - Revive zero-copy about GET execution on object-server | 02:49 |
| takashi | kota_: It's very cool patch. I think we can use that idea to improve data transfer, especially when we send data processed by storlet to web socket. I'll have a deep look later. :-) | 02:55 |
