Harmony Core Office Hours, December 2019

Jeff and Steve give an update on Harmony Core development activities over the last six weeks, which included the following.

Traditional Bridge has been updated to use the new system.text.json parser and writer. This reduces overhead when running traditional Synergy methods, resulting in significant performance improvements (a full order of magnitude from what we’ve seen). This enhancement is built on the version 11 Synergy/DE runtime, so it requires version 11 on the traditional side of the bridge. Traditional Bridge still works with prior versions, but these versions can’t take advantage of the built-in JSON libraries that make the performance improvements possible.

We created a prototype with EF Core 3.1 support. Microsoft has completely reworked the model for providers, so this prototype took quite a bit of work. The reworked model is an improvement; it makes query analysis requirements more explicit, so the Harmony Core EF Provider does not have to do as much pattern mapping for optimization. We will continue to improve this support, and we’ll transition the project from prototype to production.

We also made several improvements to project templates. The metadata that is injected into data models has been extended, and some data models have additional attributes that improve the fidelity of generated documentation. These attributes provide additional information about the HTTP responses each operation endpoint can generate, along with the shape of the data that is returned by each operation. This should provide much better information for Swagger documentation. These changes will be checked into the Harmony Core Github repository in the next couple of days.

Finally, we fixed a customer-reported bug that caused duplicate items in multi-leg joins (issue 131), and we continued work on Harmony Core Generator, a utility designed to replace regen.bat and display relations.
