Data freshness data quality checks, SQL examples

A table-level check that calculates the time difference between the most recent row in the table and the current time. The timestamp column that is used for comparison is defined as the timestamp_columns.event_timestamp_column on the table configuration. This check is also known as "Data Freshness".

---

The data freshness data quality check has the following variants for each type of data quality checks supported by DQOps.

profile data freshness

Check description

Calculates the number of days since the most recent event timestamp (freshness)

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
profile_data_freshness	Data freshness (Maximum age of the most recent row)	timeliness	profiling		Timeliness	data_freshness	max_days

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the profile data freshness data quality check.

Managing profile data freshness check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name  -ch=profile_data_freshness --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=profile_data_freshness --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=profile_data_freshness --enable-warning
                    -Wmax_days=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name  -ch=profile_data_freshness --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=profile_data_freshness --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=profile_data_freshness --enable-error
                    -Emax_days=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the profile_data_freshness check on all tables on a single data source.

dqo> check run -c=data_source_name -ch=profile_data_freshness

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=profile_data_freshness

You can also run this check on all tables on which the profile_data_freshness check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_*  -ch=profile_data_freshness

YAML configuration

The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.

daily data freshness

Check description

Daily calculating the number of days since the most recent event timestamp (freshness)

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
daily_data_freshness	Data freshness (Maximum age of the most recent row)	timeliness	monitoring	daily	Timeliness	data_freshness	max_days

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the daily data freshness data quality check.

Managing daily data freshness check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name  -ch=daily_data_freshness --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=daily_data_freshness --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=daily_data_freshness --enable-warning
                    -Wmax_days=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name  -ch=daily_data_freshness --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=daily_data_freshness --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=daily_data_freshness --enable-error
                    -Emax_days=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the daily_data_freshness check on all tables on a single data source.

dqo> check run -c=data_source_name -ch=daily_data_freshness

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=daily_data_freshness

You can also run this check on all tables on which the daily_data_freshness check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_*  -ch=daily_data_freshness

YAML configuration

The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.

monthly data freshness

Check description

Monthly monitoring calculating the number of days since the most recent event timestamp (freshness)

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
monthly_data_freshness	Data freshness (Maximum age of the most recent row)	timeliness	monitoring	monthly	Timeliness	data_freshness	max_days

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the monthly data freshness data quality check.

Managing monthly data freshness check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name  -ch=monthly_data_freshness --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=monthly_data_freshness --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=monthly_data_freshness --enable-warning
                    -Wmax_days=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name  -ch=monthly_data_freshness --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=monthly_data_freshness --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_*  -ch=monthly_data_freshness --enable-error
                    -Emax_days=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the monthly_data_freshness check on all tables on a single data source.

dqo> check run -c=data_source_name -ch=monthly_data_freshness

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=monthly_data_freshness

You can also run this check on all tables on which the monthly_data_freshness check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_*  -ch=monthly_data_freshness

YAML configuration
