How Database Locks Kill Your App Speed

Most engineers blame slow queries for latency, but the real bottleneck is often row-level locking. In this episode, we dissect how exclusive locks on a single customer record can stall an entire database cluster during peak traffic. We look at the specific mechanics of optimistic versus pessimistic concurrency control and why ignoring lock contention costs companies millions in lost transactions every quarter. Lucas and Luna break down the trade-offs between strict consistency and system throughput. #DatabaseEngineering #ConcurrencyControl #RowLevelLocking #OptimisticLocking #PessimisticLocking #DatabasePerformance #SoftwareArchitecture #TechBusiness #ScalabilityIssues #DataConsistency #TransactionProcessing #SystemLatency #FexingoBusiness #BusinessPodcast #LucasAndLuna #TechTrends2026 #EnterpriseSoftware #CloudInfrastructure Keep every episode free: buymeacoffee.com/fexingo
