TileDB supports the Google Cloud Storage S3 compatibility mode. GCS S3 compatibility does not support multipart uploads, therefore we have added a configuration option to disable multipart uploads and use single
PutObject requests instead. Uploads in this mode may be slower than comparable operations using AWS S3. Currently,
vfs.s3.multipart_part_size should be set to a value larger than the expected file size, up to available memory or backend limits (the maximum object size for GCS is 5 TB).
The Configuration page explains how to set configuration parameters in TileDB.
