Ora che abbiamo tutte queste conoscenze, è il momento di sporcarci le mani e iniziare a sviluppare applicazioni Flink! In questo capitolo imparerai a configurare un ambiente per sviluppare, eseguire ed eseguire il debug delle applicazioni Flink. Inizieremo parlando del software necessario e di dove puoi trovare gli esempi di codice di questo libro. Utilizzando questi esempi, mostreremo come le applicazioni Flink vengono eseguite e debuggate in un IDE. Infine, mostreremo come eseguire il bootstrap di un progetto Flink Maven, il punto di partenza per una nuova applicazione.
Software necessario
Per prima cosa, parliamo del software di cui hai bisogno per sviluppare applicazioni Flink. Puoi sviluppare ed eseguire applicazioni Flink su Linux, macOS e Windows. Tuttavia, le configurazioni basate su UNIX godono del supporto più ricco di strumenti perché questo ambiente è preferito dalla maggior parte degli sviluppatori di Flink. Nel resto del capitolo assumeremo una configurazione basata su UNIX. Se sei un utente Windows, puoi utilizzare il sottosistema Windows per Linux (WSL), Cygwin o una macchina virtuale Linux per eseguire Flink in un ambiente UNIX.
L'API DataStream di Flink è disponibile per Java e Scala. Pertanto, per implementare le applicazioni DataStream di Flink è necessario ...
