This patch removes the TODO item about 'template_url' support, which has been added in https://review.openstack.org/#/c/375952/. The patch also adds two new TODO items about nova server operations. These new nova server operations will be useful for long running VM cluster instances and for load-balancing or HA. Change-Id: I6e51d289176b647a4fedc5bbaf1e31f5efff6734

Senlin TODO Item List
This document records all workitems the team want to finish in a short-term (usually a development cycle which lasts 6 month). All jobs listed here are NOT in working progress which means developers can pick up any workitem they are interested in if they do have enough time to work on it. Developer should file a BluePrint in the launchpad to give a detailed description about their plan after deciding to work on a specific item. A patch should be proposed as well to remove related workitem from the TODO list after the BP gets approval.
HIGH PRIORITY
API
- Find and fill gaps with API-WG besides the one we already identified.
- Validate API request for unexpected attributes. Such attributes should result in a 400 error. [https://review.openstack.org/#/c/260292]
ENGINE
- Scaling Improvements [https://etherpad.openstack.org/p/newton-senlin-ha]
- Ensure 'desired_capacity' will be controlled by users, not senlin engine or policies.
- Always do health check before any scaling actions.
MIDDLE PRIORITY
API
- Support advanced filters as suggested by the API WG: Filtering Guidelines
- Support to
os-request-idwhen serving api requests.- Add profile-validate and policy-validate APIs: https://etherpad.openstack.org/p/newton-senlin-validation
PROFILE
- Add support to VM migration operations for nova server profile.
- Add support to snapshot/restore operations for nova server profile. The possible use case is rapid scale.
POLICY
- Provide support for watching all objects we created on behalf of users, like loadbalancer which is created when attaching lb policy.
- Leverage other monitoring service for object health status monitoring.
DB
- Add db purge (senlin-manage) for deleting events and actions because they accumulate very fast.
LOW PRIORITY
API
- Add support to osprofiler which is a common library across all openstack projects for tracing and profiling.
ENGINE
- Allow actions to be paused and resumed. This is important for some background actions such as health checking.
- Provide support to oslo.notification and allow nodes to receive and react to those notifications accordingly: Autoscaling Notifications
POLICY
- Batching policy: create batches for node creation/deletion/update.
PROFILE
- Support disk property update for os.nova.server profile
DOC
- Provide a sample conf file for customizing senlin options.
OTHERS
- Integration with Glare for profile/policy specs storage. At least we may want to enable users to retrieve/reference heat templates from glare when creating profiles.
