Recommended code changes to accommodate updates to Azure Time Series Insights
Published date: 17 June, 2020
Azure Time Series Insights Preview is introducing support for an additional Data Type, Long (previously, TSI supported only Double). This will affect you in certain cases, and you’ll need to update Time Series Model variable expressions and/or client code. This feature will only be applied to Preview pay-as-you-go environments. If you have a Standard (S) SKU Time Series Insights environment, you will not be affected.
This change affects you in the following cases:
- If you currently use Time Series Model variables and only send integral data types in your telemetry data.
- If you currently use Time Series Model variables and send both integral and non-integral data types in your telemetry data.
- If you use categorical variables that map integer values to categories.
- If you are nearing the 1,000 property name limit in Warm Store (WS) and send both integral and non-integral data – property count can be viewed as a metric in the Azure Portal.
If any of the above cases apply to you, this article demonstrates how to apply the recommended code changes. This change will go into effect on 29 June 2020. If updates are not made, note that some of your time series accessed via the query APIs or Time Series Insights explorer will return null (i.e. it will appear as if there is no data in the explorer).
If you have any questions or concerns regarding this change, submit a support ticket through the Azure Portal and mention this blog.
