SQL Server 2022 Developer Edition is a full-featured, free version of Microsoft’s flagship database engine, specifically licensed for development and testing. It is functionally identical to the Enterprise edition, meaning you get every high-end feature—including advanced analytics and mission-critical availability—without the massive licensing cost. The Verdict: Is It Worth It?
For developers, it is the best version to download. Unlike the Express edition, which has a 10GB database limit and restricted CPU/RAM usage, the Developer edition allows you to build and test at a true enterprise scale.
Pros: Access to all Enterprise features (Intelligent Query Processing, Ledger, high availability); completely free for non-production use.
Cons: Strictly prohibited for production environments; requires a full Windows/Linux host or container. Detailed Feature Review 1. Performance: "Intelligent" Query Processing

Parameter Sensitive Plan (PSP) Optimization: Automatically handles multiple execution plans for a single query to prevent "parameter sniffing" issues where a plan for one set of data performs poorly for another.
DOP Feedback: The engine monitors queries and automatically adjusts the Degree of Parallelism (CPU usage) to find the most efficient balance. 2. Security: Blockchain-backed Ledger
A new SQL Server Ledger feature brings blockchain-like immutability to your tables. It creates a tamper-proof record of every change made to your data, which is ideal for highly regulated industries or internal auditing. What's new in SQL Server 2022 | Severalnines
