Table nodes

A table node is automatically created when you create a transform node. All table nodes have one upstream transform parent. Running the transform generates the data in this output table.

You can view the data and metadata in the table similarly to other tables on Redivis. You can not edit or update the metadata.

Sanity check output

After you run the upstream transform, you can investigate the output table to get feedback on the success and validity of your querying operation – both the filtering criteria you've applied and the new features you've created.

Understanding at the content of an output table allows you perform important sanity checks at each step of your research process, answering questions like:

  • Did my filtering criteria remove the rows I expected?

  • Do my new variables contain the information I expect?

  • Does the distribution of values in a given variable make sense?

  • Have I dropped unnecessary variables?

The best tools for sanity checking a table node are by inspecting the general table characteristics, checking the summary statistics of different variables, or looking at the cells.
