Stream Twitter to Serverless Kafka

In this blog post, the author outlines a method for creating a serverless application that searches Twitter for specific keywords and publishes the resulting tweets to a Kafka topic using Upstash. The process involves setting up a Maven project with necessary dependencies such as Twittered for Twitter API access, Kafka-clients for Kafka interaction, Log4j for logging, and AWS Lambda for serverless computing. After creating a Twitter Developer account and setting up a TwitterProducer class to handle tweet searching and publishing, the application uses an AWS Lambda function to trigger the Twitter search every 15 minutes. The tweets are then published to a Kafka topic on Upstash, showcasing the ease of integrating serverless functions with Kafka to handle data streams. The post concludes with verification steps to ensure the tweets are being correctly published and consumed, demonstrating the efficiency of using Upstash's serverless Kafka offering in conjunction with AWS Lambda.
