This is wierd. I indexed using DiskDocValuesFormat as the default codec and
observed 16K qps with BinaryDocValuesField. But with a simple StoredField,
I observed a much higher 30K qps. When I added both fields
(BinaryDocValuesField and StoredField) to the index, I observed only 100
qps on each fiel
DiskDocValuesFormat is the right thing to use: it loads certain things
into RAM, eg the compressed bits that tell it the addresses of the
bytes on disk, but then leaves the actual bytes on disk.
I believe the old DirectSource was more extreme as it left the
addresses on disk too, so there were 2 s
I made the same experiment and got same result. Then I used per-field codec
with DiskDocValuesFormat, it works like DirectSource in 4.0.0, but I'm not
feeling confident with this usage. Anyone can say more about removing
DirectSource API?
