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
