Fivetran Log Connector Sample Querieslink

---

Calculate monthly active rows (MAR) per connectorlink

The Monthly Active Rows (MAR) count sent through the Fivetran Log Connector includes the active rows recorded up to the current date. The count resets at the beginning of each month. For example, if your MAR count for schema_A.table_A is 5500 on January 1st but is 5800 on January 31st, your January MAR for schema_A.table_A is 5800. Your MAR count then drops to 0 on February 1st. To learn more about MAR, see our consumption-based pricing documentation.

Note: If you use these queries during your free trial, we recommend that you add every data source that you plan to use with Fivetran and let each connector run for 7 days under a typical load. This will give you a more accurate idea of how well Fivetran meets your business needs.

In the queries below, replace <fivetran_load_database> and <fivetran_log_schema_name> with the values from your destination. Replace <fivetran_log_schema_name> with the name of your connector in the Fivetran dashboard.

where message_event = 'sync_start' OR message_event = 'sync_end'

Troubleshoot errors and warningslink

Check records modified since last synclink

The sample queries below return the volume of data that has been inserted, updated, or deleted since your last successful sync. They also return the timestamp of your connector's last record modification. Query results are at the connector level.

Use the sample query for your destination:

• BigQuery
• Redshift
• Snowflake

Note: If you want to filter your results based on data modification type (for example, view inserts only), use the operationType field in the message_data JSON object.

Check daily modified recordslink

The sample queries below return the volume of data that has been inserted, updated, or deleted each day. Query results are at the table level.

Use the sample query for your destination:

• BigQuery
• Redshift
• Snowflake

Note: If you want to filter your results based on data modification type (for example, view inserts only), use the operationType field in the message_data JSON object.
