Flag inactive / deprecated time series - and only display active ones by default

Once in a while we make changes to our telemetry setup in such a way that certain time series get deprecated. This happens when we change control systems, or make changes in our telemetry pipeline, or even discontinue operations at a location. We want to have the “deprecated” time series available in CDF, but it would be useful for us if these would not by default appear in search, or in the asset hierarchy, or through grafana and other solutions.

 

It would be useful if there was a way to mark a time series as deprecated or as only containing historical data - and that in order to have the time series returned in search or list operations, the user would have to make an active choice to include those time series. My suggestion is an “isDeprecated” property on each time series.

 

There are other solutions to the problem, but these all seem to make it more difficult for the user than simply not showing deprecated time series by default:

  • Metadata field - isDeprecated (boolean)
  • Move deprecated time series to a different data set
  • Separate data models for “active” and “non-active” time series

Hi Kristian,

Just to confirm my understanding, you want to be able to control whether a time series instance is included in a Search, or any other application, and to do this you’re suggesting we implement a standard Boolean property on Time Series instances that allows users to determine that behaviour (isDeprecated could the name for the property).

Is it sufficient that this is implemented only on the newer core data model types, or is it also required that we support this on ‘classic’ time series instances?

Have I understood this correctly?

Correct! The basic need is to have a good way to per default filter out those time series that are no longer active. And to be able to show them by making an active choice - like the “show archived data sets” button in the data catalog in Fusion - a “show archived/deprecated time series” button in Search. 

For my immediate wishlist, I would have liked to see such a property/functionality on the classic time series type.

But I’m aware that CDF is moving more towards the core data model. So feel free to interpret my product idea as a suggestion only for core data model types :-)

Understood and thanks very much for the clarification. 

Tagging colleagues who are involved in building the front end user experiences where Time Series shows up to ensure we have a holistic perspective.  I think your request makes a lot of sense, especially where we have customers generating multiple instances of time series for essentially the same data, but whilst previous instances need to be stored for historical purposes, they are undesirable to show up by default in searches etc.

This is a great suggestion, thanks.
