For example, the entire DSL is non-nullable: public interface SelectWhereStep<R extends Record> extends SelectConnectByStep<R> { @NotNull @CheckReturnValue @Support SelectConditionStep<R> where(Condition condition); // ... } It makes sense to give this guarantee especially to … Continue reading Detect Accidental Blocking Calls when Using R2DBC

Asynchronous SQL Execution with jOOQ and Java 8’s CompletableFuture

Reactive programming is the new buzzword, which essentially just means asynchronous programming or messaging. Fact is that functional syntax greatly helps with structuring asynchronous execution chains, and today, we'll see how we can do this in Java 8 using jOOQ and the new CompletableFuture API. In fact, things are quite simple: // Initiate an asynchronous … Continue reading Asynchronous SQL Execution with jOOQ and Java 8’s CompletableFuture
