[DOC] USAGE GUIDE

Generate Default Snapshot

./bin/generate-xdr-snapshot

Generates 1M entries in ~15 seconds → snapshot_1m.json (3.5 GB)

Custom Sizes

# Testing (100K entries)
./bin/generate-xdr-snapshot -count=100000 -output=test.json

# Stress testing (5M entries)
./bin/generate-xdr-snapshot -count=5000000 -output=snapshot_5m.json

# Reproducible benchmark
./bin/generate-xdr-snapshot -count=1000000 -seed=12345

Using Helper Script

# Generate
./scripts/generate-snapshot.sh generate --count 1000000

# Run tests
./scripts/generate-snapshot.sh test

# Run benchmarks
./scripts/generate-snapshot.sh bench

# Clean up
./scripts/generate-snapshot.sh clean

Integration with Benchmarks

func BenchmarkSnapshotLoader(b *testing.B) {
    snap, _ := snapshot.Load("snapshot_1m.json")
    
    b.ResetTimer()
    for i := 0; i < b.N; i++ {
        ProcessSnapshot(snap)
    }
}
