Alexander Kolbasov commented on SENTRY-2370:
--------------------------------------------
Can you elaborate on the caching strategy? Is it only for the case when NN
failed to get a full snapshot? How do you invalidate the cache if something
changed since then?
> Create a cache of PathUpdates to send to NN

> When NN requests path updates from sentry and if it exceeds the time
> threshold, on consecutive attempts sentry will attempt to fetch the full
> update from scratch. Instead it should cache it and update the cache before
> sending it to NN.
