Core
Concurrency and Thread SafetyWhen multiple threads touch shared mutable state, interleavings produce race conditions: lost updates, torn reads, corrupted data. Thread safety means correctness under any interleaving. Locks/mutexes enforce mutual exclusion (pessimistic); optimistic concurrency checks for conflicts at commit and retries (compare-and-swap, version columns). Atomic operations skip locks for simple updates. Deadlock shows up when locks are acquired in conflicting orders. AI, ML, and GenAI engineer interviews probe it because inference servers, batching queues, and shared caches are all concurrent, and the classic double-increment bug still shows up in production.⚙️ System Design for AI in ProductionSign in
Core
Transactions, ACID, and Isolation LevelsA transaction bundles multiple reads and writes so the whole set either commits together or rolls back together, backed by the ACID guarantees of atomicity, consistency, isolation, and durability. The isolation level is the knob that balances concurrency anomalies (dirty reads, non-repeatable reads, phantoms) against throughput, and most databases ship with a weaker default than engineers expect. AI, ML, and data interviews probe it because pipelines that overlook isolation yield silent, intermittent corruption that no unit test will catch.🗄️ Data & SQL EngineeringSign in
