Raxol.Core.ErrorRecovery.EnhancedPatternLearner (Raxol v2.0.1)

View Source

Enhanced error pattern learning specifically for recovery scenarios.

This module extends the existing ErrorPatternLearner with recovery-specific features like success rate tracking for different recovery strategies, integration with the recovery supervisor, and adaptive strategy selection.

Features

  • Recovery strategy success rate tracking
  • Context-aware pattern analysis
  • Integration with RecoverySupervisor
  • Adaptive strategy recommendation
  • Performance impact correlation

Usage

# Record a recovery attempt
EnhancedPatternLearner.record_recovery_attempt(
  error_signature,
  :circuit_break,
  :success,
  %{recovery_time_ms: 2500}
)

# Get recommended recovery strategy
strategy = EnhancedPatternLearner.recommend_recovery_strategy(
  error_signature,
  %{restart_count: 3, performance_impact: :high}
)
