If you are hitting memory limits, you could almost go very old-school:-
Probably slow because of the disk access and if it's too big, then diff may also struggle.
Not the best, but a clunky way to be sure it will actually work. Perhaps this will give you a good basis to see what output from a better (more efficient) process should be.

flow-expire
flow-expire(1) General Commands Manual flow-expire(1)NAME
flow-expire -- Manage storage of flow file archives by expiring old data.
SYNOPSIS
flow-expire [-h] [-d debug_level] [-e expire_count] [-E expire_size] -w workdir
DESCRIPTION
The flow-expire utility will remove the oldest flow files in a directory based on either a count of files or space utilization. The direc-
tory is recursively searched for flow files. Files that do not have a flow-tools signature will be ignored. The internal timestamp is
used so backups or copies of the flow files that do not retain the original timestamp will not impact the operation of flow-expire. flow-
expire is typically used to manage storage in a distributed environment where flows are collected on a different server than they are
archived.
OPTIONS -d debug_level
Enable debugging.
-e expire_count
Retain the maximum number of files so that the total file count is less than expire_count.
-E expire_size
Retain the maximum number of files so that the total storage is less than expire_size. The letters b,K,M,G can be used as multi-
pliers, ie 16 Megabytes is 16M.
-h Display help.
-w workdir
Work in workdir.
EXAMPLES
Remove the oldest flow files in /flows/krc4 until the total storage is less then 2 Gigabytes.
flow-expire -E2Gig -w /flows/krc4
Remove the oldest flow files in /flows/krc4 until the total number of files is less then 100.
flow-expire -e100 -w /flows/krc4
BUGS
Empty directories are not removed.
