Flink iterations
WebAug 13, 2024 · I'd like to write a Flink streaming operator that maintains say 1500-2000 maps per key, with each map containing perhaps 100,000s of elements of ~100B. Most records will trigger inserts and reads, but I’d also like to support occasional fast iteration of entire nested maps. WebFlink programs implement iterative algorithms by defining a step function and embedding it into a special iteration operator. There are two variants of this operator: Iterate and Delta Iterate. Both operators repeatedly invoke the step function on the current iteration state until a certain termination condition is reached.
