📰 Dev.to · abdu masah
Speed up PostgreSQL writes by 850x with a single line of Python code using executemany() with the right parameters
Action Steps
- Import the psycopg2 library to connect to PostgreSQL from Python
- Use the executemany() function with the 'batch_size' parameter to optimize write performance
- Test the performance difference by comparing execution times with and without batch_size
- Apply this optimization to your existing data loading scripts to achieve significant speedups
- Monitor and adjust the batch_size parameter for optimal performance with your specific dataset
