        [![PyPI version](https://badge.fury.io/py/Faker-Events.svg)](https://pypi.org/project/Faker-Events/)
        
        Generates Events with formatted fake data for streams. The intention is for
         development and testing purposes without relying on real data.
        
        ## Usage
        Using Faker Events is a library, and doesn't come with a CLI.  This is in part
        due to the Events you create being written in Python as objects.
        
        This library utilises the Faker package to generate it's data on the profile.
        Understanding how Faker works is recommended and you can find the documentation
        for it [here](https://faker.readthedocs.io/en/stable/).
        
        ### Installation
        By default faker-events simply prints to standard out.  To use a stream, give
        the option when installing.
        
        **Kafka**
        ```bash
        pip install faker-events[kafka]
        ```
        
        **Kinesis**
        ```bash
        pip install faker-events[kinesis]
        ```
        
        ### Starting a Stream
        Create an Event Generator and start using Live Stream. By default only 10
        profiles are created.  Giving large numbers can take sometime to build so
        becareful.
        
        Set the "Events Per Minute" on the live_stream method to change the maximum
        allowed, but subject to system performance also.  The default is ~60 per
        minute, but they are random so expect potentially lower rates.
        
        **Console**
        ```python
        import faker_events
        
        eg = faker_events.EventGenerator(num_profiles=100)
        eg.live_stream(epm=120)
        ```
        
        Output
        ```json
        {"type": "example", "event_id": 1, "user_id": 1609288, "first_name": "David", "last_name": "Herrera"}
        {"type": "example", "event_id": 2, "user_id": 1609288, "first_name": "David", "last_name": "Herrera"}
        {"type": "example", "event_id": 3, "user_id": 500, "first_name": "Samantha", "last_name": "Sanchez"}
        {"type": "example", "event_id": 4, "user_id": 500, "first_name": "Samantha", "last_name": "Sanchez"}
        {"type": "example", "event_id": 5, "user_id": 500, "first_name": "Samantha", "last_name": "Sanchez"}
        {"type": "example", "event_id": 6, "user_id": 1609288, "first_name": "David", "last_name": "Herrera"}
        {"type": "example", "event_id": 7, "user_id": 500, "first_name": "Samantha", "last_name": "Sanchez"}
        {"type": "example", "event_id": 8, "user_id": 1609288, "first_name": "David", "last_name": "Herrera"}
        {"type": "example", "event_id": 9, "user_id": 500, "first_name": "Samantha", "last_name": "Sanchez"}
        {"type": "example", "event_id": 10, "user_id": 500, "first_name": "Samantha", "last_name": "Sanchez"}
        ^C
        Stopping Event Stream
        ```
        
        ### Using Stream Handlers
        
        By default the JSON messages are only displayed on the standard output.  You
        can however create a stream handler to send the JSON messages to Kakfa, or
        Kinesis.
        
        **Kafka**
        ```python
        import faker_events
        
        example = faker_events.Stream(stype='kafka', host='kafka:9092', name='example')
        eg = faker_events.EventGenerator(stream=example)
        eg.live_stream()
        ```
        
        **Kinesis**
        ```python
        import faker_events
        
        example = faker_events.Stream(stype='kinesis', name='example', key='key')
        eg = faker_events.EventGenerator(stream=example)
        eg.live_stream()
        ```
        
        ### Starting a Batch
        Create an Event Generator and use the batch method, with a start and finish
        datetime object, and the frequncy like on the live stream.
        
        
        ```python
        from datetime import datetime, timedelta
        
        import faker_events
        
        eg = faker_events.EventGenerator(num_profiles=1)
        
        start = datetime(2019, 1, 1)  # No one wants to relive 2020...
        finish = start + timedelta(seconds=10)
        
        eg.batch(start, finish, epm=10)
        ```
        
        ## Data Points
        
        ### Event Data Points
        
        The Event Type has some basic data points about the event that can be used
        within the profiled method. (Access the Attribute using self)
        
        * event_id - The id of the particular event
        * event_time - The time the event occured (ISO Format)
        
        ### Profile Data Points
        
        When you create the Event Generator, the profiles you will use in the events
        are created with a number of data points. Below is a list of attributes that
        can be used on the 'profile' object within the EventType Profiled method.
        
        * id
        * uuid
        * username
        * gender
        * first_name
        * last_name
        * prefix_name
        * suffix_name
        * birthdate
        * blood_group
        * email
        * employer
        * job
        * full_address1
        * building_number1
        * street_name1
        * street_suffix1
        * state1
        * postcode1
        * city1
        * phone1
        * full_address2
        * building_number2
        * street_name2
        * street_suffix2
        * state2
        * postcode2
        * city2
        * phone2
        * driver_license
        * license_plate
        
        ## Creating a Custom Record
        Create an Event Type that has an 'event' dictionary.  If you want values to be
        processed for each event, create a function called 'profiled', and thats takes
        a dict and returns an updated dict.
        
        The profile is a randomly selected profile from the profiles created by the
        Event Generator.  You can use details from the profile to build our events
        that simulate customers, or entities.
        
        ```python
        import faker
        import faker_events
        
        fake = faker.Faker()
        
        class NewEvent(faker_events.EventType):
            event = {
                'Fixed': 'Doesnt Change',
                'Once': fake.color(),
                'Always': '',
                'Profiled': '',
            }
        
            def profiled(self, profile):
                new_details = {
                    'Always': fake.boolean(),
                    'Profiled': profile.email,
                }
                self.event.update(new_details)
        
        eg = faker_events.EventGenerator(num_profiles=2)
        eg.first_event = NewEvent()
        eg.live_stream()
        ```
        
        ## Event Sequences
        
        You can sequence the events by setting the next event to occur, and occurence
        on how many times it will happen.  If no limit is set, the next Event Type will
        never be used.
        
        
        ```python
        import faker_events
        
        eg = faker_events.EventGenerator(num_profiles=1)
        
        class EventA(faker_events.EventType):
            event = {'Name': 'A'}
        
        class EventB(faker_events.EventType):
            event = {'Name': 'B'}
        
        class EventC(faker_events.EventType):
            event = {'Name': 'C'}
        
        a = EventA(1)
        b = EventB(2)
        c = EventC(1)
        
        a.next = b
        b.next = c
        
        eg.first_event = a
        eg.live_stream()
        ```
        
        **Output**
        ```
        {"Name": "A"}
        {"Name": "B"}
        {"Name": "B"}
        {"Name": "C"}
        Event limited reached.  4 in total generated
        ```
        
        ### Using the Profile for Event State
        
        If you need to update the details of the profile, or add persistant data from
        the events you can do so within the Profiled method of the EventType instance.
        When using sequenced events, the profile can be used to retrieve the data from
        previous events.
        
        ```python
        import faker_events
        
        eg = faker_events.EventGenerator(num_profiles=1)
        
        class EventA(faker_events.EventType):
            event = {'Name': 'A', 'LastEvent': 'none'}
        
            def profiled(self, profile):
                profile.LastEvent = self.__class__.__name__
        
        class EventB(faker_events.EventType):
            event = {'Name': 'B', 'LastEvent': 'none'}
        
            def profiled(self, profile):
                self.event['LastEvent'] = profile.LastEvent
                profile.LastEvent = self.__class__.__name__
        
        class EventC(faker_events.EventType):
            event = {'Name': 'C', 'LastEvent': 'none'}
        
            def profiled(self, profile):
                self.event['LastEvent'] = profile.LastEvent
        
        a = EventA(1)
        b = EventB(1)
        c = EventC(1)
        
        a.next = b
        b.next = c
        
        eg.first_event = a
        eg.live_stream()
        ```
        
        Output
        ```
        {"Name": "A", "LastEvent": "none"}
        {"Name": "B", "LastEvent": "EventA"}
        {"Name": "C", "LastEvent": "EventB"}
        Event limit reached.  3 in total generated
        ```
