Create Listener

Two ways to define listener

Listener

from superduper import Listener
db.apply(
    Listener(
        key='key_name',
        model=model,
        select=select,
    )
)        

model.to_linstener

db.apply(model.to_listener(key='key_name', select=select))        

Data passed into the model

Single Field

# Model predict function definition: model.predict(x)
# Data example in database: {"key_name": 10}
# Then the listener will call model.predict(10)
from superduper import Listener
db.apply(
    Listener(
        key='key_name',
        model=model,
        select=select,
    )
)        

Multiple fields(*args)

# Model predict function definition: model.predict(x1, x2)
# Data example in database: {"key_name_1": 10, "key_name_2": 100}
# Then the listener will call model.predict(10, 100)
from superduper import Listener
db.apply(
    Listener(
        key=['key_name_1', 'key_name_2'],
        model=model,
        select=select,
    )
)        

Multiple fields(*kwargs)

# Model predict function definition: model.predict(x1, x2)
# Data example in database: {"key_name_1": 10, "key_name_2": 100}
# Then the listener will call model.predict(x1=10, x2=100)
from superduper import Listener
db.apply(
    Listener(
        key={"key_name_1": "x1", "key_name_2": "x2"},
        model=model,
        select=select,
    )
)
