…6003) Today we evict all cache files that belong to a given searchable snapshot directory when this directory is closed or if the Clear Cache API is used. This eviction iterates over all cache entries and find the entries that matches a given shard. We can be more specific than that by recreating the cache keys to evict from the list of file names instead of iterating over entries.
