Use Cases Event-Driven Applications: Stateful applications that ingest events from one-or more-event streams and react to incoming events by triggering computations, state updates, or external actions. Apache Flink excels in handling the concept of time and state for these applications, and can scale to manage very large data volumes (up to several terabytes). It has a rich set of APIs, ranging from low-level controls to high-level functionality, like Flink SQL, enabling developers to choose the most suitable options for the implementation of advanced business logic. Apache Flink’s outstanding feature for event-driven applications is its support for savepoints. A savepoint is a consistent state image that can be used as a starting point for compatible applications. Given a savepoint, an application can be updated or adapt its scale, or multiple versions of an application can be started for A/B testing. Examples: Fraud detection Anomaly detection Rule-based alerting Business process monitoring Web application (social network)   Data Analytics Applications: With a sophisticated stream processing engine, analytics can be performed in real-time. Streaming queries or applications ingest real-time event streams and continuously produce and update results as events are consumed. The results are written to an external database or maintained as internal state. A dashboard application can read the latest results from the external database or directly query the internal state of the application. Apache Flink supports streaming as well as batch analytical applications. Examples: Quality monitoring of telco networks Analysis of product updates & experiment evaluation in mobile applications Ad-hoc analysis of live data in consumer technology Large-scale graph analysis   Data Pipeline Applications: Streaming data pipelines serve a similar purpose as Extract-Transform-Load (ETL) jobs. They transform and enrich data and can move it from one storage system to another. However, they operate in a continuous streaming mode instead of being periodically triggered. Hence, they can read records from sources that continuously produce data and move it with low latency to their destination. Examples: Real-time search index building in e-commerce Continuous ETL in e-commerce   Public Resources New - What’s New in Cloudera Streaming Analytics - Kubernetes Operator 1.2 Updated - Cloudera Streaming Analytics - Kubernetes Operator Documentation Cloudera Stream Processing Product Page Cloudera Kubernetes Operators documentation homepage Cloudera Stream Processing Community Edition Accelerate Streaming Pipeline Deployments with New Kubernetes Operators (webinar recording) Updated - Cloudera Stream Processing & Analytics Support Lifecycle Policy   ...

This is a key release that adds strong streaming analytics capabilities to complement the Kafka features of the Operator. Cloudera SQL Stream Builder is available in Tech Preview in this release. While Kubernetes started out as a container orchestration platform where customers would mostly run stateless applications and APIs, it has now matured to a point where it can run stateful, large scale data processing frameworks such as Apache Flink and Apache Kafka. We have seen this shift in Kubernetes usage in our customer base and are excited to meet them where they are. Enabling Flink applications on Kubernetes is an important part of our vision and complements Cloudera's end-to-end Data in Motion story on Kubernetes. Use Case The Cloudera Streaming - Kubernetes Operator allows Flink and Kafka customers to deploy their workloads on existing shared Kubernetes clusters. The Kubernetes Operator automates the installation and lifecycle management of applications on Kubernetes, significantly lowering the cost of operations and allowing customers to focus on use case implementation instead of cluster operations. For customers, this means that they can take advantage of: Greater hybrid portability and accelerated deployments via streamlined life cycle management Increased resource efficiency via shared clusters Improved scalability via Kubernetes orchestration tools like OpenShift Release Highlights Cloudera Streaming Analytics Operator 1.0 (Flink and SQL Stream Builder) Deploys and manages Flink and SQL Stream Builder Supports Flink 1.18.1 SQL Stream Builder is available in Tech Preview (no support) Auto-scaling for Flink deployments PyFlink support Enterprise ready Prometheus integration for monitoring This adds to the the following Streaming Operator capabilities, released earlier: Cloudera Streaming Messaging Operator 1.0 (Kafka) Deploys and manages Kafka, Zookeeper, and Cruise Control Supports Kafka 3.7 Provides rack awareness and high availability Supports various authentication options (OAuth, LDAP, mTLS, PLAIN) Supports authorization through Kafka Access Control Lists (ACL) Prometheus integration for monitoring Learn More Watch the recording of our release webinar showcasing an end-to-end financial services use case running on the new Kubernetes Operators.
