AC Austin C. Community Organizer + Hackathon Co-Founder Small-Business (50 or fewer emp.) 11/25/2018 "Robust, Supportive Community, Challenging but Improving Deployments" 4/5 What do you like best about Apache Flink? The API is intuitive and flexible enough for all use cases we had. The support from dataArtisans and the mailing list they monitor makes using the platform much safer in an enterprise setting - we would have been lost without their support, often within the same day. Resources can be found on their Community page at https://flink.apache.org/community.html. We also love the blog posts put out by dataArtisans of real case studies. Review collected by and hosted on G2.com. What do you dislike about Apache Flink? Deploying was easy enough for the basic case, but understanding the Hadoop / YARN ecosystem in conjunction with Flink, and creating a stable + scalable cluster, has been challenging. This is not so much a fault of Flink, but they are working to make it easier to deploy across a variety of platforms. Review collected by and hosted on G2.com. Recommendations to others considering Apache Flink: Definitely research the entire Apache BigData ecosystem - you'll save time and pain if you understand the core architecture before you start building. Review collected by and hosted on G2.com. What problems is Apache Flink solving and how is that benefiting you? We've created a real-time big data processor, which can handle hundreds of thousands of messages a day and scale up to hundred of milliions a day when necessary.
