Deprecated: The IO datatype and it’s related type classes will disappear in Arrow 0.13.0. All useful operations are offered directly over suspend functions by Arrow Fx Coroutines. https://arrow-kt.io/docs/fx/async/
Establishes the maximum stack depth for IO#map operations.
The default is 128, from which we substract one as an
optimization. This default has been reached like this:
- according to official docs, the default stack size on 32-bits Windows and Linux was 320 KB, whereas for 64-bits it is 1024 KB
- according to measurements chaining
Function1references uses approximately 32 bytes of stack space on a 64 bits system; this could be lower if “compressed oops” is activated - therefore a “map fusion” that goes 128 in stack depth can use about 4 KB of stack space
