This is the standard donkey data store. The "data" folder is what we call a "tub"
The following datatypes are supported.

Tub is an append only format, that is optimized for reads (to speed up training models).
It maintains indexes for records, and uses memory mapped files.
Tub exposes an
Iterator that can be used to read records. These iterators can be further used by
Pipelines to do arbitrary transformations of data prior to training (for data augumentation).
from donkeycar.parts.tub_v2 import Tub # Here we define records that have a single `input` of type `int`. inputs = ['input'] types = ['int'] tub = Tub(path, inputs, types)
