ADO.NET Provider for Google BigQuery

Build 26.0.9770

ChunkSize

Specifies the size in megabytes of each chunk sent to Google Cloud Storage when uploading objects.

Data Type

int

Default Value

5

Remarks

This property controls how files are divided when uploading to Google Cloud Storage (GCS) using the UploadObject stored procedure or PUT...INTO statements. The file is sent in sequential chunks, each of the specified size.

The default (and minimum) value of 5 MB suits most upload scenarios. Increasing this value reduces the total number of upload requests but increases the amount of data that must be sent per request, which can improve throughput on high-bandwidth connections when uploading large files.
