dotnet/orleans v3.2.0

on GitHub

3.2.0 includes two major changes

• Pluggable grain directory

This feature allows to use external storage as an option for keeping grain directory information. Directory plugins can be configured for different grain classes independently, so that different consistency/availability tradeoffs can be made for different grain classes.
As part of this change, we had to remove support for multi-cluster functionality. We intend to bring it back as a grain directory plugin at a later time. Removal of multi-clustering is the only breaking change, and only if you used the feature previously.

• Switch to using .NET thread pool for scheduling

Since the initial release, Orleans has been using its own custom thread pool implementation to make up for the deficiencies in the .NET thread pool. Since then, the .NET thread pool has improved significantly, and there is no need any more for a separate solution within Orleans.

We measured a performance increase of 3.2.0 compared to 3.1.6 of 12% to 20% depending on the test scenario.
