SDK with caching (Cyrus pattern) 3. Naive SDK usage (lazy loading) Includes: - Comprehensive comparison documentation - 3 benchmark scenarios with reproduction scripts - Recommendations by use case (AI agents, CLI, automation) - Real-world performance data Pattern references: - agent2linear M15 optimizations (MILESTONES.md) - Cyrus caching approach (ceedaragents/cyrus) - Linear SDK documentation Helps users choose the right tool for their workflow. Benchmark scenarios: - Scenario 1: Fetch 50 issues (14.6x faster) - Scenario 2: List 25 projects (9.5x faster) - Scenario 3: Update issue with validation (2.9x faster) All benchmarks are reproducible with provided shell scripts. --- docs/performance/README.md | 348 ++++++++++++++++++ docs/performance/benchmarks/README.md | 143 +++++++ .../benchmarks/run-all-benchmarks.sh | 201 ++++++++++ .../benchmarks/scenario-1-fetch-issues.sh | 179 +++++++++ .../benchmarks/scenario-2-list-projects.sh | 161 ++++++++ .../benchmarks/scenario-3-update-issue.sh | 194 ++++++++++ 6 files changed, 1226 insertions(+) create mode 100644 docs/performance/README.md create mode 100644 docs/performance/benchmarks/README.md create mode 100755 docs/performance/benchmarks/run-all-benchmarks.sh create mode 100755 docs/performance/benchmarks/scenario-1-fetch-issues.sh create mode 100755 docs/performance/benchmarks/scenario-2-list-projects.sh create mode 100755 docs/performance/benchmarks/scenario-3-update-issue.sh diff --git a/docs/performance/README.md b/docs/performance/README.md new file mode 100644 index 0000000..2c0e921 --- /dev/null +++ b/docs/performance/README.md @@ -0,0 +1,348 @@ +# Linear API Performance Benchmarks + +This document compares performance characteristics of different Linear API integration patterns to help you choose the right approach for your use case. + +## TL;DR - Which Approach Should I Use? + +| Use Case | Recommended Approach | Why | +|----------|---------------------|-----| +| **AI Agents & Automation** | agent2linear | Minimizes API calls, predictable performance | +| **Interactive CLI Tools** | agent2linear | Fast response times, efficient bulk operations | +| **Quick Scripts** | Naive SDK | Simple setup, acceptable for small datasets | +| **Repeated Access Patterns** | SDK + Caching | Benefits from cached data after initial fetch | + +## Approaches Compared + +### 1. agent2linear (Custom GraphQL) + +**Strategy**: Replace `@linear/sdk` lazy loading with comprehensive custom GraphQL queries upfront. + +**Pros**: +- **Minimal API calls**: 1 query fetches all related data +- **Predictable performance**: No surprise N+1 queries +- **Token efficient**: Critical for AI agents with context window limits + +**Cons**: +- **Higher initial complexity**: Must write custom GraphQL queries +- **Maintenance**: Queries need updates when Linear schema changes + +**Example** (from `src/lib/linear-client.ts:1334-1569`): +```typescript +// Single query fetches issue + state + assignee + team + labels + comments +const query = ` + query GetFullIssue($id: String!) { + issue(id: $id) { + id + identifier + title + state { id name type } + assignee { id name email } + team { id name key } + labels { nodes { id name color } } + comments { nodes { id body user { name } } } + } + } +`; +``` + +**Performance**: See [Scenario 1](#scenario-1-fetch-50-issues-with-full-details) below. + +--- + +### 2.
