[FEATURE] Improve evaluation performance #1453

Open beeme1mr opened 1 week ago

beeme1mr commented 1 week ago

Overview

The flag evaluation engine in flagd leverages JsonLogic to provide a powerful and flexible rule-based serializable logic. The flagd binary and in-process Go flagd provider use this library. To improve flag evaluation performance and reduce computational overhead, the ruleset should be pre-decoded when a flag set is loaded (or updated). This removes the need to parse the JsonLogic structure for each evaluation.

### Tasks
- [ ] [Add support for pre-decoded rules in the Go JsonLogic SDK](https://github.com/diegoholiveira/jsonlogic/issues/88).
- [ ] Update flagd to use the pre-decoded rules.
- [ ] 🥇 Bonus points for running a performance test to measure the improvements

This should be a non-breaking change in the Go JsonLogic SDK.
