phyrrhic might be interesting for you as you use python.
Indeed sorting is just idiomatic python code using snapshot properties. Example code:
from operator import attrgetter
from pathlib import Path
from pprint import pp
from pyrrhic.repo.repository import Repository, get_masterkey
repopath = Path("restic_test_repositories/restic_test_repository")
masterkey = get_masterkey(repopath, "password")
repository = Repository(repopath, masterkey)
pp(sorted(repository.get_snapshot(), key=attrgetter("time")))
Results in:
[Snapshot(time=resticdatetime(2022, 7, 19, 21, 52, 28, 692251, tzinfo=datetime.timezone(datetime.timedelta(seconds=7200))), tree='a5dbcc77f63f5dd4f4c67c988aba4a19817aaa9d6c34a6021236a5d40ce653e1', paths=['/home/juergen/shared/python/pyrrhic/test'], hostname='shaun', username='juergen', id='dd62b535d10bd8f24440cc300a868d6bf2f472859f1218883b0a6faca364c10c', uid=1000, gid=1000, excludes=None, tags=None),

However, on a short look it seems that with pyrrhic you are restricted to a local backend
Yes, I plan to add remote repositories in future versions (rclone).
I think it’s not speed- or memory-usage- optimized
Amazingly, some operations are even faster. The low-level libraries pyrrhic uses are all implemented in C. Listing snapshots:

real 0m0,925s
user 0m0,883s
sys 0m0,040s
