Deadlock Detection
Category: science
An automated process within a database management system to identify and resolve cyclic lock dependencies.
Detection is the "referee." The database constantly maps who is locking what. If it spots a loop, it breaks it. Without automatic detection, the entire database would freeze permanently, requiring a manual human intervention and a cold system restart.
Common Examples
- The deadlock detection system identified the recursive lock conflict and killed the lower-priority process, immediately restoring service.
- Robust deadlock detection is a critical feature of high-concurrency database engines, ensuring that they can handle thousands of concurrent updates.
