# CreateUploadRequest
## Properties
**checksum_algo** | Option<**String**> | Integrity checksum algorithm you are volunteering for this file. Currently only `sha256` is accepted. Optional; pair with `checksum_value`. | [optional]
**checksum_value** | Option<**String**> | Integrity checksum value, paired with `checksum_algo`. Optional. | [optional]
**content_encoding** | Option<**String**> | Content encoding to record for the uploaded file (for example `gzip`). Optional. | [optional]
**content_type** | Option<**String**> | Content type to record for the uploaded file (for example the Parquet, CSV, or JSON MIME type). Optional. | [optional]
**declared_size_bytes** | **i64** | The exact size, in bytes, of the file you will upload. Validated at create time against the maximum allowed size, and again at finalize against the bytes actually stored — a mismatch fails the finalize. |
**filename** | Option<**String**> | Original file name, recorded with the upload for your own bookkeeping. Optional and advisory — it does not affect where the bytes are stored or how they are loaded. | [optional]
**part_size** | Option<**i64**> | Preferred size, in bytes, of each part for a large (multi-part) upload. Optional hint — the service clamps it to the allowed part-size range and to the maximum number of parts, and ignores it for small files uploaded with a single `PUT`. Omit to let the service choose. | [optional]
