Examples do not show pickling to and from a file

[d40cht]

I'd like to pickle an object which is in-memory resident at over 8Gb. I can't pickle this to a string - is there an interface to pickle directly to a file? If so, could we show it in the README?

Hi there, thanks a lot for bringing this up. Apologies for the delay, been on the road nonstop since you reported this.

At the time that you wrote this, we had no direct support for pickling to a file. But I've just added that support. I've not tested it with anything as big as 8gb, though the newly added support seems to work for modestly-sized objects.

To give you a sample of what it looks like:

case class Person(name: String, nums: Array[Int])
val p = Person("James", (1 to 200).toArray)

val file = new File("test.json")
val fileOut = new TextFileOutput(file)

p.pickleTo(fileOut)

fileOut.close()

Could you let us know if that works for your use case? If not, if you run into any other issues, please don't hesitate to drop me a line, I'd be happy to help you support your use case. heather.miller@epfl.ch

Hmmm, what about binary formats? I couldn't find BinaryFileOutput or something similar.
