Review Insertion Efficiency with Actual Performance Data


Analyzing INSERT Performance with EXPLAIN ANALYZE

Write a PostgreSQL query to analyze the performance of an INSERT statement using EXPLAIN ANALYZE.

Solution:

-- Analyze the performance of inserting a new record into the Orders table.
EXPLAIN ANALYZE 
INSERT INTO Orders (order_id, customer_id, order_date, status)
VALUES (101, 205, '2025-03-02', 'pending');

Explanation:

  • Purpose of the Query:
    • To assess the execution plan and actual performance for an INSERT operation.
    • Provides insights on how data insertion impacts system resources.
  • Key Components:
    • EXPLAIN ANALYZE : Runs the INSERT and displays performance metrics.
    • INSERT INTO Orders ... VALUES (...) : The operation being analyzed.
  • Real-World Application:
    • Helps in tuning bulk insert operations or understanding transaction overhead.

Notes:

  • Running EXPLAIN ANALYZE on DML statements will execute them; consider wrapping in a transaction for testing.

  • Write a PostgreSQL query using EXPLAIN ANALYZE to evaluate an INSERT statement with a RETURNING clause on the "Products" table.
  • Write a PostgreSQL query using EXPLAIN ANALYZE to analyze the performance of an INSERT into the "Users" table that uses default values.
