Pipeline: trim unneeded fields

[nlebovits]

Describe the task

Review and optimize the data_utils module to ensure that each function outputs only the necessary fields.

The goal is to review all functions within the data_utils module and modify them as needed to ensure that the output includes only the necessary fields. This task is critical for optimizing data processing and reducing unnecessary data overhead.

Acceptance Criteria

• Review each function in the data_utils module.
• Identify and document unnecessary fields currently included in the output of each function.
• Modify each function to exclude the unnecessary fields.
• Test each modified function to ensure it still performs as expected and outputs only the necessary fields.

Additional context

• Ensure that modifications do not break any existing functionality or dependent modules.
• Coordinate with the team to understand the required fields for each function, if unclear.
