[Backend #9] Understand isolation levels & read phenomena in MySQL & PostgreSQL via examples

When working with database transactions, one crucial thing we must do is choosing the appropriate isolation level for our application. Although there’s a well-defined standard, each database engine might choose to implement it in a different way, and thus may behave differently in each isolation level. In this video, we will explore deeply how each level of isolation work in MySQL and Postgres by running some concrete SQL queries. It also shows you how each isolation level prevents read phenomena like dirty read, non-repeatable read, phantom read, and serialization anomaly.
