Git Shallow Clones: Performance Pitfalls and the Depth 2 Optimization

2025-02-12

Git shallow clones (`--depth 1`) can significantly impact performance on the first push. This is because shallow clones artificially mark some commits as root commits, preventing the server from using optimizations and requiring the transmission of the entire commit snapshot. Using `--depth 2` deep clones, however, preserves a complete commit history, allowing the server to utilize optimizations even on the first push, reducing data transfer and significantly improving push speed. Subsequent pushes are unaffected.

Best Practices for Representing Inheritance in SQL Server Databases

2024-12-17

This article explores best practices for representing inheritance relationships in SQL Server databases. Three common approaches are presented: single table inheritance, concrete table inheritance, and class table inheritance. The advantages and disadvantages of each are detailed. Single table inheritance is simple but has scalability and data integrity issues; concrete table inheritance solves these but suffers from inefficient queries; class table inheritance balances simplicity and efficiency, making it the preferred choice in most scenarios. Alternative approaches using JSON for subtype-specific fields and normalized database design are also discussed.
