Attributes

  1. NoTransientChecksum96 (type: String.t, default: nil)
    - Same as ContentChecksum96 but without transient boilerplate.
  2. SimHash (type: String.t, default: nil)
    - Deprecated. Use simhash_v2 and simhash_v2_significance instead.
  3. SimHashIsTrusted (type: boolean(), default: nil)
    -
  4. simhashV2 (type: String.t, default: nil)
    - Simhash-v2 is generated by SimHashParseHandler, designed as a complete replacement of simhash-v1 (a.k.a. the original simhash above) from ApproxDupsParseHandler. Simhash-v2 uses a revised algorithm so that it is expected to work better in most cases than simhash-v1. They coexist in current transition period, then simhash-v1 will be retired.
  5. simhashV2Significance (type: float(), default: nil)
    - Simhash-v2-significance is used to describe the confidence about the corresponding simhash-v2 value. It is defined as the average absolute difference from zero of all internal state components when finalizing a simhash-v2 value in HashMultiSetDotCauchy. We used to compare the significance against some pre-defined threshold (default: 20) to get a boolean value "trusted_simhash_v2". However, it is possible that this field is missing while "simhash_v2" is present, in such case (1) Use "SimHashIsTrusted" instead if it is present, AND/OR (2) Assume "simhash_v2" is trusted if its value is non-zero.

SimHashIsTrusted: boolean() | nil,
simhashV2: String.t() | nil,
simhashV2Significance: float() | nil
}
