Version:

Establish dataset

POST /datasets

Establishes a dataset with the specified file/directory as the dataset's root. For each file/directory, only one dataset can be established.

This operation requires space_manage_datasets privilege.

Example cURL requests

Establish dataset

curl -H "X-Auth-Token: $TOKEN" -X POST "https://$PROVIDER_HOST/api/v3/oneprovider/datasets" \
-H "Content-Type: application/json" -d '{
    "rootFileId": "'$FILE_ID'",
    "protectionFlags": ["data_protection"]
}'

Request body

application/json

Dataset properties.

Property Type & Description

Property	Type & Description
rootFileId string Id of file or directory for which dataset should be established.
protectionFlags array of strings Dataset protection flags: `data_protection` - causes all dataset's files and directories to be protected from modifying their content. `metadata_protection` - causes all dataset's files and directories to be protected from modifying their metadata (custom metadata, ACL, etc.). Can be enabled only when `data_protection` is enabled. NOTE: the file/directory can be deleted if `data_protection` flag is disabled, or when the flag is enabled but is inherited through one of its hard links. Requests to modify the data/metadata when protection is enabled will be rejected with the EPERM POSIX error. The protection flags are ignored when the dataset is in `detached` state. Changing the protection flags may not have an immediate effect, especially for files that were already opened before the change. Note however that some basic readonly file attributes (such as e.g. `atime` updated when a file is read) will be modified regardless.

rootFileId

string

Id of file or directory for which dataset should be established.

protectionFlags

array of strings

Dataset protection flags:

data_protection - causes all dataset's files and directories to be protected from modifying their content.
metadata_protection - causes all dataset's files and directories to be protected from modifying their metadata (custom metadata, ACL, etc.). Can be enabled only when data_protection is enabled.

NOTE: the file/directory can be deleted if data_protection flag is disabled, or when the flag is enabled but is inherited through one of its hard links.

Requests to modify the data/metadata when protection is enabled will be rejected with the EPERM POSIX error.

The protection flags are ignored when the dataset is in detached state.

Changing the protection flags may not have an immediate effect, especially for files that were already opened before the change.

Note however that some basic readonly file attributes (such as e.g. atime updated when a file is read) will be modified regardless.
