Compiled model performance trends

9

In investigating the compiled model changes in EF9, I noticed that things were taking quite a lot longer than expected, so I did some analysis. The model here is the...

Update internal Cosmos provider code for NRTs

3

For example, some properties of `SelectExpression` in the Cosmos provider are marked as non-nullable, but are used as nullable in the code: * Limit * Offset * Predicate

Set up build and perf testing infrastructure

10

We need a build/test environment that will allow us to run perf tests easily. We may also want simple functional/unit tests.

Use pipelines?

19

There has been some discussion about whether use of data pipelines is the way to go for highly async, highly performant binary communication such as [Tabular Data Stream (TDS)](https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-tds/b46a581a-39de-4745-b076-ec4dbb7d13ec) to...

Communication and collaboration

This issue tracks ways we will communicate and collaborate on [Woodstar (SQL Server.Core)](https://github.com/dotnet/datalab/issues/6). Please let us know what works for you, and also comment with your own ideas. Some initial...

The idea here is to take the simple scenario implemented in #11 and hack together a raw implementation using low-level .NET constructors to hard-code some TDS. This gives us an...

This will give us an initial baseline for current performance. The scenario should be _really simple_.

At least for SQL Server, probably for Cosmos. Also, we can do getting started examples for other providers (like PostgreSQL) that don't require database installation.

Using `true` generates confusing errors if the user code that forms the basis of compiled model is changed. For example, starting with this: ```C# Console.WriteLine("Hello, World!"); public class Blog {...
