Devart SSIS Data Flow Components for Google BigQuery allow you to integrate Google BigQuery data with cloud applications and databases via SQL Server Integration Services (SSIS). Devart SSIS Data Flow Components for Google BigQuery include highly optimized Source, Destination, and Lookup components along with Devart BigQuery Connection Manager.
Devart BigQuery Source
Devart BigQuery Source component offers a convenient editor, which displays all the connection tables and their columns and allows you to quickly build a query to BigQuery via drag-n-drop. It also displays the list of available system and user variables of the package, allowing you to quickly add them to your select statements. If necessary, you can also quickly preview data, returned by the source, and check whether you query returns what you need.
Devart BigQuery Lookup
Devart BigQuery Lookup component offers very high performance because of the advanced optimization techniques used. It uses select statements that check several rows at once, and caches the returned results to reduce the number of round-trips to the server.
Devart BigQuery Destination
To speed up loading data to BigQuery, Devart BigQuery Destination splits data to multiple CSV files, uploads them to Google Cloud Storage, and then commands BigQuery to import them. It performs these jobs in parallel to provide the highest performance possible.
