When not to use Flink Try to avoid using Flink and go for other options when: You need a more matured framework compared to other competitors in the same space You need more API support apart from the Java and Scala languages There isn't many disadvantages associated with Apache Flink making it ideal choice for our use case. But it is an improved version of Apache Spark. It can run in Hadoop clusters through YARN or Spark's standalone mode, and it can process data in HDFS, HBase, Cassandra, Hive, and any Hadoop InputFormat. Sparks consolidation of disparate system capabilities (batch and stream) is one reason for its popularity. Flink offers native streaming, while Spark uses micro batches to emulate streaming. The second-generation engine manages batch and interactive processing. Amazon's CloudFormation templates don't allow for direct deployment in the private subnet. Also efficient state management will be a challenge to maintain. So the stream is always there as the underlying concept and execution is done based on that. Imprint. specialized hardware) Disadvantages: Lack of elasticity and capacity to scale (bursts) Higher cost Requires a significant amount of engineering effort Public Cloud Dataflow diagrams are executed either in parallel or pipeline manner.
