Spark has core features such as Spark Core, Spark SQL, MLib (Machine Library), GraphX (for Graph processing) and Spark Streaming and Flink is used for performing cyclic and iterative processes by iterating collections. Both Apache Spark and Apache Flink are general purpose streaming or data processing platforms in the big data environment.
Next, To run on an embedded Flink cluster, simply omit the flink_master option and an embedded Flink cluster will be automatically started and shut down for the job. The optional flink_version option may be required as well for older versions of Python. In fact, Flink CDC Connectors is a set of source connectors for Apache Flink, ingesting changes from different databases using change data capture (CDC). The Flink CDC Connectors integrates Debezium as the engine to capture data changes. So it can fully leverage the ability of Debezium. Keeping this in consideration, Apache Iceberg support both Apache Flink ‘s DataStream API and Table API to write records into iceberg table. Currently, we only integrate iceberg with apache flink 1.11.x . To create iceberg table in flink, we recommend to use Flink SQL Client because it’s easier for users to understand the concepts. Additionally, Apache Hadoop YARN is a resource provider popular with many data processing frameworks. Flink services are submitted to YARN’s ResourceManager, which spawns containers on machines managed by YARN NodeManagers. Flink deploys its JobManager and TaskManager instances into such containers.
