Query your data with BigQuery SQL directly. You can refer to source names directly in your SELECT queries, for example
SELECT datetime(timestamp) as timestamp, event_message, metadata from `MyApp.Logs` Some pointers:

• Always have a filter over the timestamp column in your WHERE clause
• Use CROSS JOIN UNNEST(my_table.my_column) as col to use nested fields in your query
• Smaller time ranges load faster
• Endpoint and alert queries can be referenced using `MyEndpointName` for query composition
