Too long same methods chain
Reports long Reactive Streams transformation chains.
Each operator method call, such as map()
or filter()
, creates some objects for those operators. Calling a long chain of operators on each subscription, for each stream element, may cause performance overhead. To avoid it, combine a long chain of calls into one operator call wherever possible.
Example:
Flux.just(1, 2, 3)
.map(it -> it + 1)
.map(it -> it + 2)
.map(it -> it + 3)
After the quick-fix is applied:
Flux.just(1, 2, 3)
.map(it -> it + 1 + 2 + 3)

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
