Activate catalog¶

See SDK reference for catalogs

In [ ]:

catalog = fb.Catalog.activate("Grocery Dataset Tutorial")

catalog = fb.Catalog.activate("Grocery Dataset Tutorial")

Set windows for aggregation¶

In [ ]:

windows = ['28d']

windows = ['28d']

Get view from table¶

See SDK reference for views

In [ ]:

# Get view from INVOICEITEMS item table.
invoiceitems_view = catalog.get_view("INVOICEITEMS")

# Get view from INVOICEITEMS item table. invoiceitems_view = catalog.get_view("INVOICEITEMS")

Extract Date parts¶

See SDK reference for view columns

See list of datetime transforms

In [ ]:

# Extract day_of_week date part from Timestamp column for INVOICEITEMS view.
invoiceitems_view["Weekday of invoice"] = invoiceitems_view["Timestamp"].dt.day_of_week

# Extract day_of_week date part from Timestamp column for INVOICEITEMS view. invoiceitems_view["Weekday of invoice"] = invoiceitems_view["Timestamp"].dt.day_of_week

Do window aggregation from INVOICEITEMS¶
