Speedup
audb.Dependencies
by usingobject
dtype for strings instead ofstring
.This decision is based on the benchmark results comparing storing string as
object
orstring
, or usingpyarrow
dtypes (for discussion on benchmark see #365). One can see that we get slight improvments when strings asobject
and not asstring
, whereas usingpyarrow
dtypes slows down row based processing.TODO: add a test what happens when we load existing
db.pkl
from cache that are usingsting
as dtype.
