Cosmos re-indexing takes longer than expected

Cosmos re-indexing takes longer than expected. Is there any way i can check if re-indexing is still happening for partitioned collection. Even though I made the index policy to none and kept back consistent, the query is throwing an error.

Solution

  • You can view the percentage progress by reading the x-ms-documentdb-collection-index-transformation-progress header in GET collection. For example in .NET, you can run the following snippet:

    // retrieve the container's details
ContainerResponse containerResponse = await client.GetContainer("database", "container")
    .ReadContainerAsync(new ContainerRequestOptions { PopulateQuotaInfo = true });
// retrieve the index transformation progress from the result
long indexTransformationProgress = long.Parse(
    containerResponse.Headers["x-ms-documentdb-collection-index-transformation-progress"]);
