Article 1Isolation Levels in Databases: Read Committed, Repeatable Read, Snapshot, and Serializable ExplainedTLDR: Isolation levels control which concurrency anomalies a transaction can see. Read Committed (PostgreSQL and Oracle's default) prevents dirty reads but still silently allows non-repeatable reads, 28 min
Article 2Cell-Based Architectures: Designing Fault Isolation Boundaries for Million-User AppsTLDR: As microservice architectures scale, a single outage in a core service can cascade across the entire system. Cell-Based Architecture mitigates this by partitioning the entire system into small, 10 min
Article 3ACID Properties Explained: How SQL Databases Guarantee Atomicity, Consistency, Isolation, and DurabilityTLDR: ACID is four orthogonal guarantees that every SQL transaction must provide. Atomicity says all-or-nothing: PostgreSQL implements it via WAL rollback; MySQL InnoDB via undo logs. Consistency says38 min
Article 4Write Skew Explained: The Anomaly That Requires Serializable IsolationTLDR: Write skew is the hardest concurrency anomaly to reason about: two concurrent transactions each read a shared condition, decide they can safely proceed, and then write to different rows. No indi23 min
Article 5Dirty Write Explained: When Uncommitted Data Gets OverwrittenTLDR: A dirty write occurs when Transaction B overwrites data that Transaction A has written but not yet committed. The result is not a rollback or an error — it is silently inconsistent committed dat28 min
Article 6Read Skew Explained: Inconsistent Snapshots Across Multiple ObjectsTLDR: Read skew occurs when a transaction reads two logically related objects at different points in time — one before and one after a concurrent transaction commits — producing a view that never exis34 minPage 1 of 3
