I would like to create a batch of items, make an HTTP request with this batch (all of the items are needed as par

Answer 1

It could be easily done using Reactor:

Flux.fromStream(fileReader.lines().onClose(() -> safeClose(fileReader)))
            .map(line -> someProcessingOfSingleLine(line))
            .buffer(BUFFER_SIZE)
            .subscribe(apiService::makeHttpRequest);
