This project is an exemplary implementation of a caching solution, within a concurrent environment. Two producer are simultaneously parsing text-files and populating a shared cache. A PrintOutService will print the results to the console when the processing is finished.
Producer (2 x TextFileProcessor) -> Cache -> Consumer (PrintOutService)
The ThreadPool is set to a maximum of 3 Threads, if more than two files are ought to be concurrently processed, then the pool size should be adjusted.
The directory containing the files are set to an absolute path in the application.properties. To run the application
locally, this path needs to be updated to the hosting system.
The process method returns an empty CompletableFuture in order to flag when the processing is finished and signal the PrintOutService that it can traverse the Cache to print out the statistics.
For this project the Hazelcast implementation of the JCache standard is used. Only methods defined in the JSR-107 are being used, it should therefore be easily replaceable by other implementations c.f.: JSR-107 implementations
