Major upgrade of the runtime, focusing on performance and ease of use.
Does away with written streams for eventhandlers, and changes it to stream directly from the eventlog. Perfomance is roughly 2X the latest V8 releases, even without enabling concurrency.
It also does away with several limitations around changing existing eventhandlers, and will no longer validate that the new event set matches the old one.
Upgrading from V8 to V9 should be non-breaking, but downgrading from 9 to 8 is not fully supported.
Added
Concurrency support for eventhandlers
Changed
Event handler CLI will now use eventlog stream position instead of the eventhandler stream position.
Internal libraries have been updated, improving runtime performanced.
Fixed
Both the runtime and SDK will now always disconnect cleanly, and wait until all current processing is completed.
Removed
Limitations around changing consumed event handler event types after the fact
Embeddings
Eventhandler streams (database changes)
Public filter validation (improves startup time for producers)
