Vincent-Philippe Lauzon has done some performance testing of Cosmos DB when querying geospatial data:

Here are the main attributes of the sample set:

  • There are 1 200 000 documents
  • Documents are distributed on 4000 logical partitions with 300 documents per logical partition
  • %33 of documents (i.e. 400 000 documents) have a location node with a geospatial “point” in there
  • Points are scattered uniformly on the geospatial rectangle
  • There are no correlation between the partition key and the geospatial point coordinates

We ran the tests with 4 different Request Units (RUs) configurations:

  • 2500

  • 10000

  • 20000

  • 100000

Read on for the test results and his findings.
