Decoding CockroachDB: SQL Modernization Without EvalPlanQual
CockroachDB represents a significant shift in traditional SQL database paradigms by sidestepping the EvalPlanQual in PostgreSQL’s approach to handling subqueries in modifying statements. By implementing alternative strategies, CockroachDB enhances the scalability and concurrency that newer, distributed SQL databases aim to provide. The absence of EvalPlanQual in CockroachDB’s design underscores an evolution towards simplifying database architectures…
