Can we check s3 file or Glue partitions available using sagemaker pipeline?

Question

One of data pipeline creates inference input datasets in s3 weeekly. I wan to execute model inference pipeline developed in sagemaker. I have limited exposure to sagemaker pipeline .Any guidance is appreciated.

question.

1. Can I trigger the inference pipeline at certain time in a week (Batch processing)?
2. Can I include sensor (like file dependency ) once job is started?
