Flink stateful functions
WebStateful applications process dataflows with operations that store and access information across multiple events. There are two basic types of states in Flink: keyed state and … WebStateful Functions is based on iteration and arbitrary message passing. Because records can go in any direction through the dataflow, event time is not well defined. Share …

Ideally we would be able to do this in a standalone program, but being able to do this in a Flink job would be workable. Our functions are implemented in Node.js, but I assume I'll need to use Java to view persisted state.
WebFor fault-tolerant state, the ProcessFunction gives access to Flink’s keyed state, accessible via the RuntimeContext, similar to the way other stateful functions can access keyed state. The timers allow applications to react to changes in processing time and in event time. WebStateful Functions runtime, which manages state and messaging for an application, is built on top of Apache Flink, which means it inherits Flink’s deployment and operations …
