v1.22.0 - Add GetExperimentLayer

New method GetExperimentLayer to retrieve the layer name an experiment belongs to

  • get experiment layer (#177)

Full Changelog: v1.21.0...1.22.0

v1.21.0 - Optimize local mode initialization

Introduced 2 new options to configure the load strategy of the IP to country lookup & UA parser.

• IPCountryOptions
  • Disabled: Fully disable IP to country lookup
  • LazyLoad: Load in background
  • EnsureLoaded: Wait until loaded when needed
• UAParserOptions
  • Disabled: Fully disable UA parser
  • LazyLoad: Load in background
  • EnsureLoaded: Wait until loaded when needed

These are 2 of the more expensive processes during initialization of the SDK outside of network requests.

• If your service does not rely on country based checks from an IP address, disabling IPCountry is recommended.
• If your service does not rely on parsing the UserAgent, disabling UAParser is recommended.
• LazyLoad is generally recommended to avoid waiting to initialize these on start up. EnsureLoaded will ensure that it's loaded when eventually needed for evaluation.

Bug fix:

• Disable internal error logging in Local Mode

Included In This Release

• 3b13ae3 kenny-statsig
  • skip network error handling if in local mode (#174)
• 9cff2f5 kenny-statsig
  • optimize synchronous initialization processes (#173)

Full Changelog: v1.20.0...1.21.0

v1.20.0 - Optimizations & persistent storage updates

Made optimizations to evaluation logic:

• Unmarshal spec defaultValue and rule returnValue on initialization (rather than per evaluation)
• Remove unnecessary string conversion for layer assignment
• Replace array contains with map lookup
• Replace Sprintf with strconv

Impact

• Reduces layer evaluation for layers with partial allocation by about 50%
• Reduces general evaluation for dynamic configs, experiments, layers by about 15%

---

• Refactored persistent storage interface to include experiment name to solve for concurrent user evaluations across SDK instances

Included In This Release

• b171689 kenny-statsig
  • support persisted layers (#171)
• 6f1aea8 kenny-statsig
  • refactor persistent storage (#170)
• 8fcd077 kenny-statsig
