Data Lake Limitations

Atlas Data Lake supports the following Amazon S3 storage classes only:

Atlas Data Lake routes your Data Lake requests through one of the following regions only:

Data Lake Regions
AWS Regions
Virginia, USA
Oregon, USA
Sao Paulo, Brazil
London, England
Frankfurt, Germany
Mumbai, India
Sydney, Australia

Data Lake does not support the following features:

  • Creating Indexes
  • Monitoring Data Lakes with Atlas monitoring tools
  • Creating a Data Lake with S3 buckets from more than one AWS account
  • Querying documents larger than 16MB
  • Returning more than 100 collections for wildcard collections
  • Returning documents in the same order across queries unless imposed by the query operators used
  • Having more than 60 guaranteed simultaneous connections per region to a Data Lake
  • Running more than 30 simultaneous queries on your Data Lake

    If your aggregation pipeline only contains the $currentOp stage, Atlas Data Lake doesn't enforce the limit on the maximum number of simultaneous queries. You can run queries that only contain the $currentOp stage even after you reach the maximum number of simultaneous queries.


    Atlas Data Lake automatically expires your cursor if you do not consume at least 16MiB of results every 1 minute.
