Row-Level & Cell-Level Security in SQL Server with Label Security Toolkit

The free SQL Server Label Security Toolkit enables Row-Level Security (RLS) and Cell-Level Security (CLS) by applying security labels—sensitivity markings consisting of categories—to data rows and cells. Users gain access only if their clearance (tied to Windows AD accounts, SQL logins, or DB roles/groups) matches the label; includes metadata tables, helper procs/functions, vwVisibleLabels view, and a GUI for schema design. A cost-effective layer for compliance (SOX, HIPAA) that works on top of

Open-source on GitHub for anyone to clone, run, or extend.

SQL Server Always On Availability Groups: Worker Thread Capacity Planning

Worker thread capacity is a critical factor when planning SQL Server Always On Availability Groups, as replicas share an HADR pool while using unshared log capture, send, and redo threads per database. Minimum threads required = (Database Count × (1 + Secondary Replicas)) + 1, often consuming a significant portion of available threads (max worker threads minus 40). Poor planning risks thread exhaustion, failed database joins, and the need to drop/recreate AGs in production.
