RVR-BQ-RDBMS-012

1. Issue Summary:

   • The error "FAILED_TO_FIND_INCREMENT_FIELD_IN_MAPPING" with Error Code: RVR-BQ-RDBMS-012 indicates that Rivery failed to find the increment field in the mapping for a BigQuery source (bq_src). This typically occurs when an incremental loading method is configured, but the specified field to track increments is missing or not correctly identified in the mapping.
   • Incremental loads require a field (usually a timestamp or ID) to track new or updated data since the last extraction. Without this field, the platform cannot determine changes, leading to the error.

2. Action Steps:

   • Review the configuration of the River involving the BigQuery source to ensure that the correct incremental field is specified.
   • Go to the mapping section of your River configuration:
     • Ensure that the incremental field is present and correctly mapped. This field should be set as a timestamp or a unique identifier that reflects changes such as updates or insertions.
     • Verify that changes in this field correspond correctly to the data changes intended for extraction.
   • If the field should be present but is not available in the mapping, check the schema of the BigQuery table to ensure it is currently a part of the dataset.
   • Update the River configuration to include this field if it is missing. Resync the schema if changes have been made to the BigQuery source since the River was last configured.
