⚡ Optimize SQLiteSpanExporter batch insertions#116
Conversation
💡 What: Replaced the loop executing single INSERT OR REPLACE statements in SQLiteSpanExporter.export with a single conn.executemany statement using a generator expression. 🎯 Why: To resolve an N+1 query issue. SQLite has to compile and execute each statement separately in a loop, whereas executemany allows executing multiple sets of parameters against a single prepared statement, lowering CPU load and overhead. 📊 Measured Improvement: In a benchmark testing the insertion of 100,000 mock spans into a file-based temporary SQLite database: - Baseline: ~1.09 seconds. - Optimized: ~0.81 seconds. - Improvement: ~25.7% speedup over baseline.
