We are looking at merging this in a few days if there is no additional feedback.
Also, in case someone has experience with adding new services to a project. Is there a general way of requesting rpms etc to be updated for the next release to support the new services? Especially for the workflows that are handled outside of the official openstack repos. ________________________________ From: Erik Olof Gunnar Andersson eandersson@blizzard.com Sent: Monday, November 4, 2019 5:11 PM To: openstack-discuss@lists.openstack.org openstack-discuss@lists.openstack.org Cc: Duc Truong dtruong@blizzard.com Subject: [Senlin] Splitting senlin-engine into three services
We are looking into splitting the senlin-engine into three components (senlin-conductor, senlin-engine and senlin-health-manager) and wanted to get some feedback.
The main goal here is to make the components more resilient and to reduce the number of threads per worker. Each one of the components already had it's own thread pool and in theory each worker could end up with thousands of thread.
In the current version (Train) the engine process hosts these services. https://github.com/openstack/senlin/blob/stable/train/senlin/engine/dispatch...https://urldefense.com/v3/__https://github.com/openstack/senlin/blob/stable/train/senlin/engine/dispatcher.py*L31__;Iw!2E0gRdhhnqPNNL0!3beNVRHaycRfV2OvKXmcXKA-_6IY9M0ZPSl41PZIdbysXr8VPx_iQYFi6E2ibmpScw$ https://github.com/openstack/senlin/blob/stable/train/senlin/engine/health_m...https://urldefense.com/v3/__https://github.com/openstack/senlin/blob/stable/train/senlin/engine/health_manager.py*L865__;Iw!2E0gRdhhnqPNNL0!3beNVRHaycRfV2OvKXmcXKA-_6IY9M0ZPSl41PZIdbysXr8VPx_iQYFi6E1RSxLiRg$ https://github.com/openstack/senlin/blob/stable/train/senlin/engine/service....https://urldefense.com/v3/__https://github.com/openstack/senlin/blob/stable/train/senlin/engine/service.py*L79__;Iw!2E0gRdhhnqPNNL0!3beNVRHaycRfV2OvKXmcXKA-_6IY9M0ZPSl41PZIdbysXr8VPx_iQYFi6E3gBevNpA$
In my patch we move two our of these out of the engine and into it's own service namespace.
