Syntax of Requested Metrics for Store Metrics Action in case of Column Pair Map Expectation

Hi Team,

Please help me with an example or pointer to documentation to properly set requested metrics for “Column Pair Map Expectation” type like “expect_column_pair_values_to_be_equal”.

I was successful to set it up for “Column Map Expectation” like “expect_column_values_to_not_be_null”.

Documentation mentioned use of:

expectation_suite_name:
metric_name:
- metric_kwargs_id

Where:
metric_kwargs_id is a string representation of the Metric Kwargs that can be used as a database key.
For simple cases, it could be easily readable, such as column=Age, but when there are multiple keys and values or complex values,
it will most likely be an md5 hash of key/value pairs.

I can not find example how to create md5 hash of key/value pairs.

Here is part of my “action_list” dictionary for checkpoint.

  {
    "name": "store_metrics",
    "action": {
      "class_name": "StoreMetricsAction",
      "target_store_name": "metric_store",
      "requested_metrics": {
        "TRANSACTION_FACT Referential Integrity Tests": [
          {
            "column": {
              "DW_SECURITY_ID": [
                "expect_column_values_to_not_be_null.result.element_count",
                "expect_column_values_to_not_be_null.result.unexpected_index_list",
                "expect_column_values_to_not_be_null.result.missing_count",
                "expect_column_values_to_not_be_null.result.missing_percent",
                "expect_column_values_to_not_be_null.result.unexpected_count",
                "expect_column_values_to_not_be_null.result.unexpected_percent",
                "expect_column_values_to_not_be_null.result.unexpected_percent_nonmissing",
                "expect_column_values_to_not_be_null.result.unexpected_list",
                "expect_column_values_to_not_be_null.result.unexpected_index_query"
              ]
            }
          },
          **{ **

** “column_A,column_B”: {**
** “DW_SECURITY_ID,DIM_SECURITY_ID”: **
** [**
** “expect_column_pair_values_to_be_equal.table.row_count”,**
** "expect_column_pair_values_to_be_equal.column_pair_values.equal.filtered_row_count,**
** “expect_column_pair_values_to_be_equal.column_pair_values.equal.unexpected_count”,**
** “expect_column_pair_values_to_be_equal.column_pair_values.equal.unexpected_values”**
** ]**
** }**
},
“statistics.successful_expectations”,
“statistics.evaluated_expectations”,
“statistics.success_percent”,
“statistics.unsuccessful_expectations”
]
}
}
}

Any help is greatly appreciated. Thanks.
