Hi,
Can anyone confirm Lucene FieldCache memory requirements? I have 100 millions docs with non-tokenized field "country" (10 different countries); I expect it requires array of ("int", "long"), size of array 100,000,000, without any impact of "country" field length; it requires 600,000,000 bytes: "int" is pointer to document (Lucene document ID), and "long" is pointer to String value... Am I right, is it 600Mb just for this "country" (indexed, non-tokenized, non-boolean) field and 1 million docs? I need to calculate exact minimum RAM requirements... I believe it shouldn't depend on cardinality (distribution) of field... Thanks, Fuad
