Description 描述

Currently, the Data-Juicer's recipe and default executor support processing only a sequence of operations, such as OP1 and OP2, over the entire dataset in a linear fashion:

dataset.process([OP1, OP2])

However, to facilitate more granular control and optimize resource management, particularly in scenarios requiring batch-wise sequential processing, the following approach is envisaged:

for data_batch in dataset.batch_iterator(batch_size):
      data_batch.process([OP1, OP2])

This method allows for the application of operators in smaller, manageable batches, potentially improving efficiency, reducing memory footprint and simplifying the code implementation.

To integrate this feature into the cfg.yaml configuration file, a special token, such as dj_batched_group_ops can be proposed. This token will enable users to specify batch processing parameters directly within the configuration, as illustrated below:

process:
  - clean_email_mapper:
  - clean_links_mapper:

-->

process:
  - FusedOP:
      - batch_size: 1  # or any desired batch size
      - clean_email_mapper:
      - clean_links_mapper:
