ColumnRangeFilter(
    column_family_id,
    start_column=None,
    end_column=None,
    inclusive_start=None,
    inclusive_end=None,
)

A row filter to restrict to a range of columns.

Both the start and end column can be included or excluded in the range. By default, we include them both, but this can be changed with optional flags.

Parameters

Name	Description
column_family_id	str The column family that contains the columns. Must be of the form <code>_a-zA-Z0-9][-_.a-zA-Z0-9]</code>*.
start_column	bytes The start of the range of columns. If no value is used, the backend applies no upper bound to the values.
end_column	bytes The end of the range of columns. If no value is used, the backend applies no upper bound to the values.
inclusive_start	bool Boolean indicating if the start column should be included in the range (or excluded). Defaults to :data:True if start_column is passed and no inclusive_start was given.
inclusive_end	bool Boolean indicating if the end column should be included in the range (or excluded). Defaults to :data:True if end_column is passed and no inclusive_end was given.

Methods

to_pb

to_pb()

Converts the row filter to a protobuf.

First converts to a .data_v2_pb2.ColumnRange and then uses it in the column_range_filter field.

Returns

Type	Description
.data_v2_pb2.RowFilter	The converted current object.
