Anton Dmitriev updated IGNITE-8666:
-----------------------------------
Description: So far we use straightforward strategy to feed data into
partition based dataset. We retrieve all entries from an upstream cache
partition, transform it somehow and write into correspondent dataset partition
(data and context). As result we can't choose the data to be fed into dataset
and data to be not fed. To implement IGNITE-8667 (Splitting of dataset to test
and training sets) and IGNITE-8668 (K-fold cross validation of models) we need
to have such ability.
> Add ability of filtering data during datasets creation
