Amazon Personalize Upload Interactions

This node uploads interaction data to the Amazon Personalize space. The input table must contain at least two string columns that contain user IDs and item IDs and one numeric column that contains timestamps. Optionally, columns containing event types and event values can be selected. Metadata columns are not required but can be included as well (string or numeric). First, this node uploads the data to a specified S3 location. From there, it will be imported to Personalize. The import may take several minutes. If the import is done, the file will be deleted from S3 afterwards since it is not needed anymore.
To create a model with Amazon Personalize, you can also upload users and items data to the same data group. Only the interactions data is required. Once you have uploaded all the data, you can create a solution with the Amazon Personalize Create Solution Version node and afterwards deploy the solution by creating a campaign with the Amazon Personalize Create Campaign node.
More information is available on the website or in the documentation.

Note: If the node execution is interrupted during the import, e.g. by the user or due to lost of internet connection, the import will still be completed on AWS, although the node does not execute successfully. The file on S3 may not be deleted in this case.

Options

Target on S3

Specify the location on S3 which will be used to store the dataset while it gets imported to Personalize. The file is just temporarily stored and will be deleted after the node has been executed. If the execution of the node is interrupted or the internet connection gets lost while importing is in progress, the file may not be deleted.

Prefix of import job name

Specify a prefix for the name of the import job. During execution, to this prefix a timestamp of the execution time will be appended.

Prefix of schema name

Specify a prefix for the name of the schema. The full name will consist of this prefix and information about the metadata types.
