"I want to synchronize large files to an S3 destination without them being split into smaller files."

I apologize, but based on the information provided in the knowledge sources, it does not appear possible to synchronize large files to an S3 destination using Airbyte without them being split into smaller files. According to the discussions in the Airbyte community forums, the S3 destination in Airbyte automatically chunks large files into smaller parts. This behavior is built into the system and there is currently no user-configurable option to change the chunk size or prevent file splitting. Specifically: 1. A user asked about tweaking the chunk size for files exported to S3, and the Airbyte support team confirmed there is no way to configure this [Link](https://discuss.airbyte.io/t/1921). 2. Another discussion mentioned that the option to set

part_size_mb

was deprecated to achieve parallel stream syncs to S3 [Link](https://discuss.airbyte.io/t/2292). 3. Multiple examples in the forum posts show that Airbyte splits large files into numbered parts when syncing to S3 [Link](https://discuss.airbyte.io/t/1489). Given this information, it seems that file splitting is a core part of how Airbyte handles large data transfers to S3, and there's currently no built-in way to bypass this behavior. If you require transferring large files to S3 as single, unsplit files, you may need to explore alternative solutions outside of Airbyte.

When I synchronize around 5GB of data from S3 to S3, I'm seeing it split into many small files at the S3 destination.
