Data import starts every day at 10 AM accordingly to the timezone set in your Google Analytics View.
When you create a pipeline, OWOX BI imports historical data from your Google Analytics View for the previous six months. The tables with the imported data will be appearing in Google BigQuery gradually, starting with the latest date. Importing all the data takes up to 48 hours, depending on the data's overall amount.
The regular daily data import usually takes up to 2 hours. If a large amount of your Google Analytics data has been retroactively updated, table updates and creation can take up to 24 hours.
There also can be an import holdup when the Google Analytics API query limit is exceeded. This may happen when other services, aside from OWOX BI, make queries to your View's data. In this case, data import for some of the days can be postponed, but these data will appear in BigQuery during one of the next daily updates.
