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:

Sao Paulo, Brazil

eu-west-1

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.

    Important

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