Performance and latency of the Analytics Service for VSTS


When you use the Analytics Service for reporting, you’ll want to understand the performance and data latency issues associated with the service. To get started using the Analytics Service, see what is the Analytics Service.


Feature availability: The Analytics Marketplace extension is available to all VSTS accounts. Installing it provides several advanced widgets, access to the OData feed and Power BI integration.

Installing Analytics for the first time

When you install the Analytics Marketplace Extension, you should expect the initial setup to take between 5 to 30 minutes. If after 24 hours you aren't able to access your data, contact Microsoft Support.

Query Performance

Using the recommended query patterns, the Analytics Service will respond to any aggregation or non-aggregated query query within 3 to 5 seconds. The query response will be paged if it exceeds 10,000 results.

Some of the entity sets available in Analytics are designed for aggregations. The service will limit the results from these Entities to a single page for any non-aggregated query as outlined in the recommended query patterns.


When you use Analytics, you query a curated copy of the data stored in Visual Studio Team Services (VSTS). The data copy helps optimize read and aggregation performance, and greatly reduces the impact reporting scenarios have on VSTS.

Because the data is copied, the Analytics Service is not a real-time time store. Copying the data introduces a 5 to 30 second delay before the data associated with any one change shows up in Analytics.
