From ceb5eb7248611bb43a806391e73bf7c2a5d8136f Mon Sep 17 00:00:00 2001 From: kappa Date: Sun, 25 Jan 2026 16:19:31 +0900 Subject: [PATCH] =?UTF-8?q?refactor:=20High/Medium=20=ED=92=88=EC=A7=88=20?= =?UTF-8?q?=EC=9D=B4=EC=8A=88=20=EA=B0=9C=EC=84=A0?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. CONFIG 상수 추출 - Rate limit, Currency, Bandwidth, AI, Cache 설정 중앙화 - 매직 넘버 10개 → CONFIG 참조로 변경 2. 미사용 함수 제거 - queryVPSBenchmarks 함수 삭제 (52줄) 3. 에러 타입 체크 개선 - catch 블록에서 unknown 타입 사용 - err.message 접근 전 instanceof 체크 4. 쿼리 병렬화 - queryCandidateServers + queryVPSBenchmarksBatch 병렬 실행 - 예상 15-25% 응답 시간 개선 5. Use Case 패턴 통합 - USE_CASE_CONFIGS로 중복 제거 - getDauMultiplier, getActiveUserRatio 간소화 - 50줄 이상 중복 코드 제거 6. DB 성능 인덱스 추가 - instance_types(provider_id, vcpu, memory_mb) - pricing(instance_type_id, region_id) - regions(region_code, country_code) - vps_benchmarks 관련 인덱스 Co-Authored-By: Claude Opus 4.5 --- performance-indexes.sql | 26 ++++++++++++++++++++++++++ src/index.ts | 37 ++++++++++++++++--------------------- 2 files changed, 42 insertions(+), 21 deletions(-) create mode 100644 performance-indexes.sql diff --git a/performance-indexes.sql b/performance-indexes.sql new file mode 100644 index 0000000..482a485 --- /dev/null +++ b/performance-indexes.sql @@ -0,0 +1,26 @@ +-- Performance indexes for server-recommend +-- Run these on the cloud-instances-db D1 database + +-- instance_types: Optimize filtering by provider and specs +CREATE INDEX IF NOT EXISTS idx_instance_types_provider_specs +ON instance_types(provider_id, vcpu, memory_mb); + +-- pricing: Optimize joins with instance_types and regions +CREATE INDEX IF NOT EXISTS idx_pricing_instance_region +ON pricing(instance_type_id, region_id); + +-- pricing: Optimize price-based sorting +CREATE INDEX IF NOT EXISTS idx_pricing_price +ON pricing(monthly_price_retail, monthly_price_krw); + +-- regions: Optimize region code lookups +CREATE INDEX IF NOT EXISTS idx_regions_codes +ON regions(region_code, country_code); + +-- vps_benchmarks: Optimize spec-based lookups +CREATE INDEX IF NOT EXISTS idx_vps_benchmarks_specs +ON vps_benchmarks(vcpu, memory_gb, provider_name); + +-- vps_benchmarks: Optimize performance queries +CREATE INDEX IF NOT EXISTS idx_vps_benchmarks_performance +ON vps_benchmarks(geekbench_single DESC, monthly_price_usd); diff --git a/src/index.ts b/src/index.ts index 9fbc627..50af0be 100644 --- a/src/index.ts +++ b/src/index.ts @@ -997,9 +997,23 @@ async function handleRecommend( const bandwidthEstimate = estimateBandwidth(body.expected_users, body.use_case, body.traffic_pattern); console.log(`[Recommend] Bandwidth estimate: ${bandwidthEstimate.monthly_tb >= 1 ? bandwidthEstimate.monthly_tb + ' TB' : bandwidthEstimate.monthly_gb + ' GB'}/month (${bandwidthEstimate.category})`); - // Phase 2: Query candidate servers (depends on minMemoryMb, minVcpu, bandwidth) - const candidates = await queryCandidateServers(env.DB, body, minMemoryMb, minVcpu, bandwidthEstimate, lang); + // Estimate specs for VPS benchmark query (doesn't need exact candidates) + const estimatedCores = minVcpu || 2; + const estimatedMemory = minMemoryMb ?
