#External table with avro formate in Big Query #bigdata #spark
Since Avro is a data serialisation system, a schema specification is necessary. JSON can be used to define Avro schemas.
The structure of your data is specified by this schema. For creating table in Big Query , Apache Hive,Spark , you may make a table in the Avro format like this one:

uris=["path till partition"]
}
Here we learn about creation of external table in big query. In your big data environment, create the table: You will build a table and indicate that it should utilise the Avro format, depending on your particular big data platform (Big Query, Hadoop, Spark, Hive, etc.). For instance, with Apache Hive, you may make a table in the Avro format.
