Bala FA dfba4ff397 doc: add multipart documentation about staging files

2016-04-05 19:56:19 -07:00

Multipart backend format

When multipart upload is used for objects, below meta-data/staging files are created

New multipart upload call creates file EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.uploadid
Put object part call creates file EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.PART_NUMBER.MD5SUM_STRING
Abort multipart call removes all files matching EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.*
Complete multipart call does
1. Create a staging file EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.complete.TEMP_NAME then rename to EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.complete
2. Rename staging file EXPORT_DIR/.minio/BUCKET/PATH/TO/OBJECT/UPLOAD_ID.complete to EXPORT_DIR/BUCKET/PATH/TO/OBJECT
