Optimize performance

BaseDoc's id

DocArray's BaseDoc has an optional id field, which defaults to ID(os.urandom(16).hex()). This takes quite some time. If you don't rely on the id anywhere, you can instead set the default to None. This increases the performance by a factor of approximately 1.4:

from docarray import BaseDoc
from docarray.typing import ID


class MyDoc(BaseDoc):
    id: ID = None
    title: str

Since BaseDoc.id is optional, you could also set the value to None, but this turns out to be a bit less efficient than the option above, and increases performance by a factor of approximately 1.2:

class MyDoc2(BaseDoc):
    title: str


doc = MyDoc2(id=None, title='bye')
