Hello,

I'm reading the docs/blog on incremental checkpoints and it says:

>You can also no longer delete old checkpoints as newer checkpoints need
them, and the history of differences between checkpoints can grow
indefinitely over time. You need to plan for larger distributed storage to
maintain the checkpoints and the network overhead to read from it.
source:
https://flink.apache.org/features/2018/01/30/incremental-checkpointing.html

I'm wondering why this would be true though. It says earlier that
incremental checkpoints compact so why would the history grow indefinitely?

Thanks!
