From 6f8b53f7dacff13d3a453db8407ca57b776f1fce Mon Sep 17 00:00:00 2001 From: nutcas3 Date: Sat, 2 May 2026 05:38:06 +0300 Subject: [PATCH] feat: Implement carrier weight updates, pricing analytics calculations, and tenant rate limiting - Add updateCarrierWeights implementation with regional and plan-based weight adjustments in carrier_methods.go - Add calculateRegionalWeightAdjustment helper with usage-based weight scaling and clamping - Add calculatePlanWeightAdjustment helper with plan usage analysis and adjustment limits - Add calculateConversionRate helper in pricing_integration.go using discount statistics and active rule ratios --- .../internal/rateplan/carrier_methods.go | 89 +++++++++++++- .../internal/services/pricing_integration.go | 41 ++++++- .../internal/services/pricing_service.go | 116 +++++++++++++++++- .../internal/services/tenant_analytics.go | 9 -- .../services/tenant_analytics_methods.go | 3 +- .../internal/tenant/middleware.go | 7 ++ 6 files changed, 246 insertions(+), 19 deletions(-) diff --git a/apps/carrier-connector/internal/rateplan/carrier_methods.go b/apps/carrier-connector/internal/rateplan/carrier_methods.go index d012795..c47bbe7 100644 --- a/apps/carrier-connector/internal/rateplan/carrier_methods.go +++ b/apps/carrier-connector/internal/rateplan/carrier_methods.go @@ -159,13 +159,94 @@ func (csi *CarrierSelectionIntegrator) calculateRelevance(plan *RatePlan, criter } func (csi *CarrierSelectionIntegrator) updateCarrierWeights(analytics *UsageAnalytics) { -
