🏷️ Labels: Postgresql, Sql Optimization, Batch Processing, Performance Tuning
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The session aimed to optimize batch insertions in PostgreSQL and analyze database performance metrics to identify and resolve bottlenecks.

Key Activities

  • Discussed performance issues related to inserting rows in PostgreSQL and suggested solutions to improve batch insert efficiency.
  • Analyzed database health metrics, including memory usage, CPU performance, and disk I/O, with recommendations for optimization.
  • Addressed the P0003 error in PostgreSQL during multi-row inserts and provided solutions.
  • Presented an optimized SQL approach for batch inserting records without using the RETURNING clause.
  • Improved SQL insertion strategies to prevent timeouts by using ID-based pagination instead of OFFSET.
  • Provided strategies for efficiently processing large datasets by limiting initial extraction to a few thousand rows.
  • Outlined methods to measure query execution time in PostgreSQL using various tools and commands.
  • Analyzed PostgreSQL EXPLAIN ANALYZE output to identify bottlenecks and suggest performance improvements.

Achievements

  • Enhanced understanding of PostgreSQL batch insert optimization techniques.
  • Developed strategies to analyze and improve database performance metrics.

Pending Tasks

  • Further testing of optimized SQL queries in a production environment to validate performance improvements.
