Download a free trial of Talend Cloud Integration Platform and see how easy it can be to go from zero to BigQuery in no time. BYTES data read from a BigQuery table are base64-encoded, unless you export to Avro format, in which case the Avro bytes data type applies. This allows BigQuery to store complex data structures and relationships between many types of Records, but doing so all within one single table. : INT64 FLOAT64; BOOL; STRING . It is a serverless cloud-based data warehouse. Tip: Data precision may be lost during conversion. Users can easily pull any data from BigQuery—such as actuals, transactions, lists, and hierarchies—straight into Anaplan models for faster planning, modeling, and analysis. For each Analytics view that is enabled for BigQuery integration, a dataset is added using the view ID as the name. The conversion between data types results in some precision loss.
