I can’t find a simple reference to explain what this >> operator does. It seems to have different uses based on the context? For example, in this walkthrough I found a code snippet:
combined_features = item_features >> UnrollFeatures(
"item_id", user_features[user_features_to_unroll]
)
Is there a simple explanation for what that operator does? Thank you!
Hey @xdageorg. Found one the docs:
A ColumnSelector describes a group of columns to be transformed by Operators in a Graph. Operators can be applied to the selected columns by shifting (>>) operators on to the ColumnSelector, which returns a new Node with the transformations applied. This lets you define a graph of operations that makes up your Graph.
If you’d like to dive deeper, note the rrshift implementation in merlin.dag.base_operator which is the parent class of UnrollFeatures
