Yes, it is possible to split the data into partitions when the destination is an S3 bucket. When syncing data to S3, Airbyte may create multiple output files, as the output files can be partitioned by size, targeting a size of 200MB compressed or lower. This behavior is mentioned in the documentation for both [S3](https://docs.airbyte.com/integrations/destinations/s3) and [S3-Glue](https://docs.airbyte.com/integrations/destinations/s3-glue) destinations. Please note that if the output bucket contains too many files, the part id variable will use a

UUID

instead of a sequential ID.
