Isolation levels: Read Committed, Repeatable Read, and Serializable explained
Database isolation levels make different tradeoffs between concurrency and consistency by controlling which anomalies concurrent transactions are allowed to observe. Read Committed prioritizes throughput but allows changing results between reads, Repeatable Read prevents many inconsistencies through snapshot isolation while still permitting write skew, and Serializable guarantees execution equivalent to a serial order by detecting or preventing conflicting transactions.
