Data Aggregation

Bubbletea offers 2 convenient methods to aggregate data into buckets.

1. beta_agregate_timeseries Process time series data by hour, day, week or month.

2. beta_aggregate_groupby Group data by a field.

As a developer, you need to specify how each data column is aggregated through the definition below.

ColumnConfig

Specify how each column is aggregated.

ColumnConfig:
        name: str
        aggregate_method: AggregateMethod
        type:ColumnType=None
        na_fill_method: NaInterpolationMethod = None,
        na_fill_value=None

• name: str

  The name of the column.

• aggregate_method

  Choose from any of AggregateMethod.

  class AggregateMethod(str, Enum):
      MEAN = ("mean",)
      SUM = ("sum",)
      FIRST = ("first",)
      LAST = ("last",)
      MEDIAN = ("median",)
      MIN = ("min",)
      MAX = ("max",)
      COUNT = "count"

• na_fill_method: NaInterpolationMethod

  By applying the aggregate_method, NA could be generated usually because of a lack of data. Choose one of NaInterpolationMethod

  • FORDWARD_FILL

    Fill NA with the previous value.

  • BACKWARD_FILL

    Fill NA backward.

    class NaInterpolationMethod(str, Enum):
        FORDWARD_FILL = ("ffill",)
        BACKWARD_FILL = ("bfill",)

• na_fill_value

  NA can be filled with literal value as well, for example 0. na_fill_method triumphs na_fill_value
