I would like to reduce this. One idea is to use a bloom filter. For example, construct a bloom filter of all keys used by files in the repository. Then for each key with content present, check if it's -in the bloom filter. Since there can be false negatives, this might +in the bloom filter. Since there can be false positives, this might miss finding some unused keys. The probability/size of filter could be tunable. |
