Flink Jobs for Confluent Manager for Apache Flink

Flink applications are deployed in Confluent Platform with Confluent Manager for Apache Flink® (CMF), which is a central management component that enables users to securely manage a fleet of Flink jobs across multiple environments.

CMF supports two ways to create and manage Flink jobs.

• Applications offer the full flexibility of Flink programs. You can use all JVM-based APIs (DataStream, Table, SQL) and submit and manage applications packaged as JAR files.

• Statements offer the ease-of-use of a native SQL interface. You can run table operations, interactive SQL statements, or submit and manage long-running SQL statements.

Applications and statements can be tuned with Flink configuration options to meet their performance, fault-tolerance, and security requirements. Applications accept all Flink configuration options. On a statement, only job-level options take effect. Cluster-level options, such as memory settings and metrics reporters, are ignored when set on a statement. Setting state.checkpoints.dir or state.savepoints.dir on a statement has no effect on savepoints or on the state kept across a stop and resume. For statements, set these options on the compute pool in spec.clusterSpec.flinkConfiguration or in the environment’s computePoolDefaults.
