why mongodb have 100mb limit per aggregation pipeline stage?

you can set allowdiskuse extend limit.

my question is, why number 100mb?

i guess won't exact answer unless mongodb core developers.

100mb arbitrary number , knowledge 100mb limit because if consider each document of size 100kb , each pipeline returns 1000 documents reaches 100mb limit.
