Join class

Performs an equality join on two DynamicFrames.

Example

We recommend that you use the DynamicFrame.join() method to join DynamicFrames. To view a code example, see Example: Use join to combine DynamicFrames.

Methods

__call__(frame1, frame2, keys1, keys2, transformation_ctx = "")

Performs an equality join on two DynamicFrames.

  • frame1 – The first DynamicFrame to join (required).

  • frame2 – The second DynamicFrame to join (required).

  • keys1 – The keys to join on for the first frame (required).

  • keys2 – The keys to join on for the second frame (required).

  • transformation_ctx – A unique string that is used to identify state information (optional).

Returns a new DynamicFrame that is created by joining the two DynamicFrames.
