schema

A JSON schema for the external table. Schema is required for CSV and JSON formats if autodetect is not on. Schema is disallowed for Google Cloud Bigtable, Cloud Datastore backups, Avro, Iceberg, ORC and Parquet formats. ~>NOTE: Because this field expects a JSON string, any changes to the string will create a diff, even if the JSON itself hasn't changed. Furthermore drift for this field cannot not be detected because BigQuery only uses this schema to compute the effective schema for the table, therefore any changes on the configured value will force the table to be recreated. This schema is effectively only applied when creating a table from an external datasource, after creation the computed schema will be stored in google_bigquery_table.schema ~>NOTE: If you set external_data_configuration.connection_id, the table schema must be specified using the top-level schema field documented above.
