Open Topics

  • We need to revisit CBOR binary support vs simple JSON / binary encoding (per Core WG meeting of 1/7/21).
    • High - How to handle binary data in V2
      • Is CBOR still the right way?
      • Simplicity versus performance
      • We should have new requirements/use cases to change this
      • Jim to find the objectors to CBOR before we cover and get any suggestions/requirements for non-CBOR
  • Use of CLI to generate new application or device service
    • Per Core WG and TSC meetings (1/20/21), there is a big desire to add a feature to EdgeX tooling to more easily generate a new device or application service (using a command line tool and some template found in the SDK)
    • Question is whether this should live in edgex-cli or is this a separate tool?
    • CLI for replacing curl scripts; this doesn't see to fall in line with objectives of the current CLI.
  • Client keys in configuration; use the service keys as the constants for the map keys (per Core WG meeting of 1/21/21)
  • We are up to 58 repositories in Holding. May need to look at some cleanup in the new year.
    • Done - resolved via email
  • Core/High - Ensure that service location data is pulled from trusted source (i.e. not Consul) (Tony's ADR)
    • Covered in Security WG
  • High - V2 API - should we add security foundation added to that (per some of earlier V2 API designs via Dell and Bryon N)?
    • Adding token to authenticate a micro service call (is this in scope for Ireland)
    • May not be needed unless all services are distributed
    • We need to explore alternatives to provide secure / locked out service to service communications
  • Med - Address how to get device resource info (for app services and Kuiper)
    • Probably not ADR worthy
    • Either provide Lenny’s convenience APIs or tool to dig out the device resource information in the (cached) profiles
    • How/when to invalidate the cache if we use the profile-digging approach
  • Med - Keep commit history from beginning to end (don’t squash them until PR approved)
  • Med - Standardizing units of measure
  • Med - Declarative Kong applicability
    • Allowing us to drop Progress DB
    • But can you configure groups/users ACL
    • Only supports JWT users
  • Low - Is the Wiki the best place to document project decisions (those outside of or smaller than ADRs).  This was our initial take.  Should we revisit?
  • Low (must be done before V2 is done) - Naming scheme changes for config.Clients (key name change)
    • Use consistent name that all other services use for core data
    • Consistency in the naming vs changing all the names to use service name as part of key
    • Related to system management hard coded list of services.
    • Separate issue in arch meeting – high once report back
    • Other naming issues (secret store vs secret service)
    • Opportunity to make all config/naming consistent
    • Jim take resp – get WG leads – try to prioritize this survey
  • Low - Revisit combine core services at least at all executables in one image
    • Release would be easier but image would be bigger with more complex compose files
  • Low - Digital twin (and LWM2M) applicability
  • Low - Time series database support and applicability
    • Ian Johnson has an example of app service to InfuxDB export (snap in the store)

Non-prioritized items

  • Allowing dynamic changes to device profiles
