# This example demonstrates how to create a stream of events,
# subscribe to this stream, and append events to the stream.

# initialize ray
ray.init()

# initialize rayvens
rayvens.init()

# create a stream
stream = rayvens.Stream('example')

# log all future events
stream >> (lambda event: print('LOG:', event))

# append two events to the stream in order
stream << 'hello' << 'world'
