Expect the column values to be decreasing.

By default, this expectation only works for numeric or datetime data. When 'parse_strings_as_datetimes=True', it can also parse strings to datetimes.

If 'strictly=True', then this expectation is only satisfied if each consecutive value is strictly decreasing--equal values are treated as failures.

expect_column_values_to_be_decreasing is a Column Map Expectation

Args:

• column (str): The column name.

Keyword Args:

• strictly (Boolean or None): If True, values must be strictly greater than previous values
• parse_strings_as_datetimes (boolean or None): If True, all non-null column values to datetimes before making comparisons
• mostly (None or a float between 0 and 1): Successful if at least mostly fraction of values match the expectation. For more detail, see mostly.

Other Parameters:

• result_format (str or None): Which output mode to use: BOOLEAN_ONLY, BASIC, COMPLETE, or SUMMARY. For more detail, see result_format.
• include_config (boolean): If True, then include the expectation config as part of the result object.
• catch_exceptions (boolean or None): If True, then catch exceptions and include them as part of the result object. For more detail, see catch_exceptions.
• meta (dict or None): A JSON-serializable dictionary (nesting allowed) that will be included in the output without modification. For more detail, see meta.

Returns:

• An ExpectationSuiteValidationResult

Exact fields vary depending on the values passed to result_format, include_config, catch_exceptions, and meta.
