Description

Summary:

Current Flux.delayElements will delay the elements since the start of the first elements. It would be nice to have another operator that will give delay between elements.

Example:

Flux.delayElements(Duration.ofHour(1)) 5 Elements arrived --> delay 1 hour --> element 1 processed --> delay 1 hour --> element 2 processed ...

Flux.delayBetween(Duration.ofHour(1)) 5 elements arrived --> element 1 processed --> delay 1 hour --> element 2 processed ...

Contributor guide

Research direction
