Describes parameters for how a Flink-based Kinesis Data Analytics application executes multiple tasks simultaneously. For more information about parallelism, see Parallel Execution in the Apache Flink Documentation.
ParallelismConfiguration is a JSON Structure definition published by Amazon Managed Service for Apache Flink, describing 4 properties, of which 1 is required. It conforms to the https://json-structure.org/meta/core/v0/# meta-schema.
