BigQuery Data Source Connection Tests and Troubleshooting

If you encounter error messages or other problems with your data source connection, check this topic for suggestions for troubleshooting.

BigQuery data source: "Too many queries"
This error results when the batch size is too small. To correct this error, open the file $CHORUS_HOME/shared/ALPINE_DATA_REPOSITORY/configuration/alpine.conf and add the configuration parameter database.bigquery.batchSize (default = 1000).
BigQuery data source: "Cannot parse query"
This error results when the batch size is too big. To correct this error, open the file $CHORUS_HOME/shared/ALPINE_DATA_REPOSITORY/configuration/alpine.conf and add the configuration parameter database.bigquery.batchSize (default = 1000).

Google recommends that BigQuery data source users insert data using the Google API. Using DML issued through JDBC can cause problems because of statement size limitations; therefore, you should avoid using TIBCO Data Science - Team Studio operators to copy data into BigQuery.
