Hoss Man commented on SOLR-7510: -------------------------------- Basic thinking i have... * FieldMuttaingUpdateProcessor * by default mutates no fields * typical usage would be after CloneFieldUpdateProcessor * looks at each field value given, and uses instanceof to pick the best method to call on the HashFunction ** if not a simple primitive, defaults to toString() then hash ** so for optimal hashing of numerics, users should put this after the appropriate Parse(Numer)UpdateProcessor *** slightly cumbersome, but mainly targeted more for string fields anyway, since that's where pre-computing hte hash values is the most important > UpdateProcessor to compute a murmur3 hash of a field at index time > ------------------------------------------------------------------ > > Key: SOLR-7510 > URL: https://issues.apache.org/jira/browse/SOLR-7510 > Project: Solr > Issue Type: Sub-task > Reporter: Hoss Man > > SOLR-6968 is adding HyperLogLog support to stats component.
