One of our team is testing the Export to GCS for the data archival. It is observed that the EXPORT DATA produces too many files (nearly 2000 files for 1 partition; filesize less than 1GB) in the storage bucket. But, if the EXPORT DATA statement has a LIMIT specified, the number of files created is reduced drastically. Is this working as expected? Any documentation somewhere about this LIMIT clause that reduces the number of files created?
