> Currently BigQuery table source determines estimated size using table.numBytes property.

> If BigQuery table has data in the streaming buffer, size of that data will not be reflected by table.numBytes. To better estimate size of table, data in the streaming buffer has to be considered as well. Size of data in streaming buffer can be determined based on property streamingBuffer.estimatedBytes according to following.
