Release notes


  • Made editorial changes to documentation comments.


  • Added support for Python 3.5.
  • Added support for connection pooling using a requests module.
  • Added support for session consistency.
  • Added support for TOP/ORDERBY queries for partitioned collections.


  • Added retry policy support for throttled requests. (Throttled requests receive a request rate too large exception, error code 429.) By default, DocumentDB retries nine times for each request when error code 429 is encountered, honoring the retryAfter time in the response header. A fixed retry interval time can now be set as part of the RetryOptions property on the ConnectionPolicy object if you want to ignore the retryAfter time returned by server between the retries. DocumentDB now waits for a maximum of 30 seconds for each request that is being throttled (irrespective of retry count) and returns the response with error code 429. This time can also be overriden in the RetryOptions property on ConnectionPolicy object.
  • DocumentDB now returns x-ms-throttle-retry-count and x-ms-throttle-retry-wait-time-ms as the response headers in every request to denote the throttle retry count and the cummulative time the request waited between the retries.
  • Removed the RetryPolicy class and the corresponding property (retry_policy) exposed on the document_client class and instead introduced a RetryOptions class exposing the RetryOptions property on ConnectionPolicy class that can be used to override some of the default retry options.


  • Added the support for multi-region database accounts.


  • Added the support for Time To Live(TTL) feature for documents.


  • Bug fixes related to server side partitioning to allow special characters in partitionkey path.



  • Add Hash & Range partition resolvers to assist with sharding applications across multiple partitions.


  • Implement Upsert. New UpsertXXX methods added to support Upsert feature.
  • Implement ID Based Routing. No public API changes, all changes internal.


  • Supports GeoSpatial index.
  • Validates id property for all resources. Ids for resources cannot contain ?, /, #, \, characters or end with a space.
  • Adds new header "index transformation progress" to ResourceResponse.


  • Implements V2 indexing policy.


  • Supports proxy connection.


  • GA SDK.

Release & retirement dates

Microsoft will provide notification at least 12 months in advance of retiring an SDK in order to smooth the transition to a newer/supported version.

New features and functionality and optimizations are only added to the current SDK, as such it is recommend that you always upgrade to the latest SDK version as early as possible.

Any request to DocumentDB using a retired SDK will be rejected by the service.


All versions of the Azure DocumentDB SDK for Python prior to version 1.0.0 will be retired on February 29, 2016.

1. How will customers be notified of the retiring SDK?

Microsoft will provide 12 month advance notification to the end of support of the retiring SDK in order to facilitate a smooth transition to a supported SDK. Further, customers will be notified through various communication channels – Azure Management Portal, Developer Center, blog post, and direct communication to assigned service administrators.

2. Can customers author applications using a "to-be" retired DocumentDB SDK during the 12 month period?

Yes, customers will have full access to author, deploy and modify applications using the "to-be" retired DocumentDB SDK during the 12 month grace period. During the 12 month grace period, customers are advised to migrate to a newer supported version of DocumentDB SDK as appropriate.

3. Can customers author and modify applications using a retired DocumentDB SDK after the 12 month notification period?

After the 12 month notification period, the SDK will be retired. Any access to DocumentDB by an applications using a retired SDK will not be permitted by the DocumentDB platform. Further, Microsoft will not provide customer support on the retired SDK.

4. What happens to Customer’s running applications that are using unsupported DocumentDB SDK version?

Any attempts made to connect to the DocumentDB service with a retired SDK version will be rejected.

5. Will new features and functionality be applied to all non-retired SDKs

New features and functionality will only be added to new versions. If you are using an old, non-retired, version of the SDK your requests to DocumentDB will still function as previous but you will not have access to any new capabilities.

6. What should I do if I cannot update my application before a cut-off date

We recommend that you upgrade to the latest SDK as early as possible. Once an SDK has been tagged for retirement you will have 12 months to update your application. If, for whatever reason, you cannot complete your application update within this timeframe then please contact the DocumentDB Team and request their assistance before the cutoff date.
