[GIO][SINGLE-ROW] New Implementation of IOGEN
This PR is a new implementation of the GIO (generating readers for custom datasets). In the new implementation, removed all hard-coded implementations for flat datasets and replaced them with code gen. One of the primary goals of GIO is to support single and multi-row representations of tuples in source datasets. This PR is for supporting single row representation and the multi-row feature will be in a separate PR.
An outline of the PR are:
- It supports Matrix and Frame
- It supports nested and flat datasets
- It supports non-standard datasets, i.e., an incomplete number of cols in a CSV file
Hi @fathollahzadeh
Is this PR still in use, or did everything move to the new PR ?
