Mapping logs to Bigquery table

When you forward your logs to BigQuery, the fields in the log will be mapped to the column in the table. By default, Apica maps the schema from the forwarder to the facet in the logs. It will insert the value for the facet as a value to the column in the table.

To change the default mapping behavior, create a forward rule for the namespace and application by renaming the facet with the column name. This will help you to manage the mappings between your log and the BigQuery table schema.
