Describe the problem

Transaction time column in the sample data contains Integer values of the transaction time-of-a-day in a format of HHmmss.
Since this is an integer (not string), we use that as feature as it is and compute averaged feature value as well.

However, to make it more semantically accurate, this should be converted into string and parsed as the time-of-a-day.

From the data science point of view, we may use hour of a day as the feature to detect if the given transactions happened within "usual" time-of-a-day.

For the aggregation feature, median value makes more sense than average, but currently we don't support Med aggregation key.

• Python Client: This is the client users use to interact with most of our API. Mostly written in Python.
• Computation Engine: The computation engine that execute the actual feature join and generation work. Mostly in Scala and Spark.
• Feature Registry API: The frontend API layer supports SQL, Purview(Atlas) as storage. The API layer is in Python(FAST API)
• Feature Registry Web UI: The Web UI for feature registry. Written in React
