This is a grouping of related issues. Feel free to vote (👍) for this issue to indicate that this is an area that you think we should spend time on, but consider also voting for individual issues for things you consider especially important.

EF9

The following work is a roughly prioritized list of work tentatively planned for the EF9 release. More details of the full scope of Cosmos work over several releases can be found in All work section below.

Important: This plan is not a commitment; it will evolve as we continue to learn throughout the release. Some things not currently planned for EF9 may get pulled in. Some things currently planned for EF9 may get punted out.

The general approach for Cosmos in EF9 is:

  • Necessary infrastructure/test work
  • Bring the query pipeline up-to-date with relational
  • As much as possible in parallel, implement high-value enhancements
    • Bring complex types support close to relational level
    • Small config items, like RBAC
    • High-value smaller query items
  • Depending on how this work goes, stretch goals are:
    • Better use of partition keys (Will do if query is in good shape in time.)
    • Partial updates and CUD batching

Completed

General improvements

Query fundamentals

Function translations

ReadItem and partition key management

Infra/internal work

Planned

No more planned work for 9 at this time.

Punted

Stretch

T-shirt sizes are:

  • Small: Days or less
  • Medium: Days to a couple of weeks
  • Large: Several weeks
  • X-Large: Many weeks

All work

These are areas either fundamental to the underlying architecture and implementation, and/or fundamental user experiences that users expect, on one side, from any EF Core provider, and on the other side by any mechanism used to access Cosmos. For example, SelectMany is a fundamental query pattern that should work on any EF Core provider. Similarly, partition keys are fundamental to working with Cosmos, and hence EF must expose/provide this functionality.

Query fundamentals

At the time of writing (beginning of EF9 work), the Cosmos query pipeline code has fallen behind the relational code by a considerable about. The architecture now employed by relational providers must be ported to Cosmos before any other major changes are made to the query pipeline.

Following this, some fundamental improvements are needed to the query pipeline. Many of these areas have model building, change tracking, update pipeline aspects as well, but they involve a lot of query work.

Non-query fundamentals

Many of these areas have query aspects, but much of the work can be done independently of query.
