How do multi-row INSERT batch statements optimize bulk ingestion speed?
❓ Interview Prompt: Explain bulk insertion techniques, multi-value `INSERT INTO table VALUES (...), (...)`, network round-trip reduction, and transaction commit batching.
Inserting 100,000 rows using individual 'INSERT' statements requires 100,000 network round-trips and transaction commits, taking minutes!
Multi-Row Batching Solution:
Combining thousands of rows into a single multi-value 'INSERT' statement ('INSERT INTO table VALUES (r1), (r2), ...') executes in a single network round-trip and transaction commit, increasing bulk throughput by over $100\times$!
Code Implementation Example
sql
-- Bulk INSERT batching multiple rows in a single statement
INSERT INTO event_logs (user_id, event_type, created_at) VALUES
(101, 'CLICK', NOW()),
(102, 'VIEW', NOW()),
(103, 'PURCHASE', NOW());💡Executing multi-row batch inserts for fast bulk ingestion.
🎯 Interview Key Takeaway
Batch multi-row INSERT statements to reduce network round-trips and maximize bulk ingestion throughput.
