> While looking at SENTRY-1907 I noticed another thing. {{sentryStore.retrieveFullPathsImage()}} uses {{Map<String, Set<String>>}} as a snapshot representation. This isn't needed since {{Map<String, Collection<String>>}} is sufficient and we can represent it using ArrayList. This is much more efficient representation.
