Model classes for use in the events storage API.

class panko.storage.models.Event(message_id, event_type, generated, traits, raw)

Bases: panko.storage.base.Model

A raw event from the source system. Events have Traits.

Metrics will be derived from one or more Events.

DEFAULT_DIR = 'asc'

DEFAULT_SORT = [('generated', 'asc'), ('message_id', 'asc')]

DUPLICATE = 1

INCOMPATIBLE_TRAIT = 3

PRIMARY_KEY = 'message_id'

SUPPORT_DIRS = ('asc', 'desc')

SUPPORT_SORT_KEYS = ('message_id', 'generated')

class panko.storage.models.Trait(name, dtype, value)

Bases: panko.storage.base.Model

A Trait is a key/value pair of data on an Event.

The value is variant record of basic data types (int, date, float, etc).

DATETIME_TYPE = 4

FLOAT_TYPE = 3

INT_TYPE = 2

NONE_TYPE = 0

TEXT_TYPE = 1

type_names = {0: 'none', 1: 'string', 2: 'integer', 3: 'float', 4: 'datetime'}

panko.storage.models.serialize_dt(value)
