I Built a Write-Ahead Log in Pure Python and Finally Understood How Databases Survive Crashes

1. 1Build a write-ahead log system using pure Python
2. 2Run the system with sample data to test its functionality
3. 3Configure the log to handle crashes and data corruption
4. 4Test the system's ability to recover from crashes
5. 5Apply the write-ahead log concept to a real-world database project

Software engineers and database administrators benefit from understanding write-ahead logs to improve data reliability and durability in their systems

💡 Write-ahead logs ensure data durability by writing changes to a log before applying them to the database
