    auth : {
        token: token
    }
};

datalake:Client baseClient = check new Client(clientConfig, serviceUrl = "https://{accountName}.{dnsSuffix}");

Step 3 - Invoke connector operation

List file systems


public function main() {
    datalake:FilesystemList|error fileSystemList = baseClient->filesystemList("account");
    if (fileSystemList is datalake:FilesystemList) {
        log:printInfo("Filesyatem List " + fileSystemList.toString());
    } else {
        log:printInfo("Error Occured");
    }
}

Append Data | Flush Data | Set Properties | Set Access Control

Parameters

filesystem string - The filesystem identifier.

pathParam string - The file or directory path.

action string - The action must be "append" to upload data to be appended to a file, "flush" to flush previously uploaded data to a file, "setProperties" to set the properties of a file or directory, or "setAccessControl" to set the owner, group, permissions, or access control list for a file or directory. Note that Hierarchical Namespace must be enabled for the account in order to use access control. Also note that the Access Control List (ACL) includes permissions for the owner, owning group, and others, so the x-ms-permissions and x-ms-acl request headers are mutually exclusive.

payload byte[] - Valid only for append operations. The data to be uploaded and appended to the file.

xMsClientRequestId string? (default ()) - A UUID recorded in the analytics logs for troubleshooting and correlation.

timeout int? (default ()) - An optional operation timeout value in seconds. The period begins when the request is received by the service. If the timeout value elapses before the operation completes, the operation fails.

xMsDate string? (default ()) - Specifies the Coordinated Universal Time (UTC) for the request. This is required when using shared key authorization.

xMsVersion string? (default ()) - Specifies the version of the REST protocol used for processing the request. This is required when using shared key authorization.

position int? (default ()) - This parameter allows the caller to upload data in parallel and control the order in which it is appended to the file. It is required when uploading data to be appended to the file and when flushing previously uploaded data to the file. The value must be the position where the data is to be appended. Uploaded data is not immediately flushed, or written, to the file. To flush, the previously uploaded data must be contiguous, the position parameter must be specified and equal to the length of the file after all data has been written, and there must not be a request entity body included with the request.

retainUncommittedData boolean? (default ()) - Valid only for flush operations. If "true", uncommitted data is retained after the flush operation completes; otherwise, the uncommitted data is deleted after the flush operation. The default is false. Data at offsets less than the specified position are written to the file when flush succeeds, but this optional parameter allows data after the flush position to be retained for a future flush operation.

close boolean? (default ()) - Azure Storage Events allow applications to receive notifications when files change. When Azure Storage Events are enabled, a file changed event is raised. This event has a property indicating whether this is the final change to distinguish the difference between an intermediate flush to a file stream and the final close of a file stream. The close query parameter is valid only when the action is "flush" and change notifications are enabled. If the value of close is "true" and the flush operation completes successfully, the service raises a file change notification with a property indicating that this is the final update (the file stream has been closed). If "false" a change notification is raised indicating the file has changed. The default is false. This query parameter is set to true by the Hadoop ABFS driver to indicate that the file stream has been closed."

contentLength int? (default ()) - Required for "Append Data" and "Flush Data". Must be 0 for "Flush Data". Must be the length of the request content in bytes for "Append Data".

contentMd5 string? (default ()) - Optional. An MD5 hash of the request content. This header is valid on "Append" and "Flush" operations. This hash is used to verify the integrity of the request content during transport. When this header is specified, the storage service compares the hash of the content that has arrived with this header value. If the two hashes do not match, the operation will fail with error code 400 (Bad Request). Note that this MD5 hash is not stored with the file. This header is associated with the request content, and not with the stored content of the file itself.

xMsLeaseId string? (default ()) - The lease ID must be specified if there is an active lease.

xMsCacheControl string? (default ()) - Optional and only valid for flush and set properties operations. The service stores this value and includes it in the "Cache-Control" response header for "Read File" operations.

xMsContentType string? (default ()) - Optional and only valid for flush and set properties operations. The service stores this value and includes it in the "Content-Type" response header for "Read File" operations.

xMsContentDisposition string? (default ()) - Optional and only valid for flush and set properties operations. The service stores this value and includes it in the "Content-Disposition" response header for "Read File" operations.

xMsContentEncoding string? (default ()) - Optional and only valid for flush and set properties operations. The service stores this value and includes it in the "Content-Encoding" response header for "Read File" operations.

xMsContentLanguage string? (default ()) - Optional and only valid for flush and set properties operations. The service stores this value and includes it in the "Content-Language" response header for "Read File" operations.

xMsContentMd5 string? (default ()) - Optional and only valid for "Flush & Set Properties" operations. The service stores this value and includes it in the "Content-Md5" response header for "Read & Get Properties" operations. If this property is not specified on the request, then the property will be cleared for the file. Subsequent calls to "Read & Get Properties" will not return this property unless it is explicitly set on that file again.

xMsProperties string? (default ()) - Optional. User-defined properties to be stored with the file or directory, in the format of a comma-separated list of name and value pairs "n1=v1, n2=v2, ...", where each value is a base64 encoded string. Note that the string may only contain ASCII characters in the ISO-8859-1 character set. Valid only for the setProperties operation. If the file or directory exists, any properties not included in the list will be removed. All properties are removed if the header is omitted. To merge new and existing properties, first get all existing properties and the current E-Tag, then make a conditional request with the E-Tag and include values for all properties.

xMsOwner string? (default ()) - Optional and valid only for the setAccessControl operation. Sets the owner of the file or directory.

xMsGroup string? (default ()) - Optional and valid only for the setAccessControl operation. Sets the owning group of the file or directory.

xMsPermissions string? (default ()) - Optional and only valid if Hierarchical Namespace is enabled for the account. Sets POSIX access permissions for the file owner, the file owning group, and others. Each class may be granted read, write, or execute permission. The sticky bit is also supported. Both symbolic (rwxrw-rw-) and 4-digit octal notation (e.g. 0766) are supported. Invalid in conjunction with x-ms-acl.

xMsAcl string? (default ()) - Optional and valid only for the setAccessControl operation. Sets POSIX access control rights on files and directories. The value is a comma-separated list of access control entries that fully replaces the existing access control list (ACL). Each access control entry (ACE) consists of a scope, a type, a user or group identifier, and permissions in the format "[scope:][type]:[id]:[permissions]". The scope must be "default" to indicate the ACE belongs to the default ACL for a directory; otherwise scope is implicit and the ACE belongs to the access ACL. There are four ACE types: "user" grants rights to the owner or a named user, "group" grants rights to the owning group or a named group, "mask" restricts rights granted to named users and the members of groups, and "other" grants rights to all users not found in any of the other entries. The user or group identifier is omitted for entries of type "mask" and "other". The user or group identifier is also omitted for the owner and owning group. The permission field is a 3-character sequence where the first character is 'r' to grant read access, the second character is 'w' to grant write access, and the third character is 'x' to grant execute permission. If access is not granted, the '-' character is used to denote that the permission is denied. For example, the following ACL grants read, write, and execute rights to the file owner and john.doe@contoso, the read right to the owning group, and nothing to everyone else: "user::rwx,user:john.doe@contoso:rwx,group::r--,other::---,mask=rwx". Invalid in conjunction with x-ms-permissions.

ifMatch string? (default ()) - Optional for Flush Data and Set Properties, but invalid for Append Data. An ETag value. Specify this header to perform the operation only if the resource's ETag matches the value specified. The ETag must be specified in quotes.

ifNoneMatch string? (default ()) - Optional for Flush Data and Set Properties, but invalid for Append Data. An ETag value or the special wildcard ("*") value. Specify this header to perform the operation only if the resource's ETag does not match the value specified. The ETag must be specified in quotes.

ifModifiedSince string? (default ()) - Optional for Flush Data and Set Properties, but invalid for Append Data. A date and time value. Specify this header to perform the operation only if the resource has been modified since the specified date and time.

ifUnmodifiedSince string? (default ()) - Optional for Flush Data and Set Properties, but invalid for Append Data. A date and time value. Specify this header to perform the operation only if the resource has not been modified since the specified date and time.

Return Type

Response|error - The data was flushed (written) to the file or the properties were set successfully.

Get Properties | Get Status | Get Access Control List | Check Access

Parameters

filesystem string - The filesystem identifier.

pathParam string - The file or directory path.

xMsClientRequestId string? (default ()) - A UUID recorded in the analytics logs for troubleshooting and correlation.

timeout int? (default ()) - An optional operation timeout value in seconds. The period begins when the request is received by the service. If the timeout value elapses before the operation completes, the operation fails.

xMsDate string? (default ()) - Specifies the Coordinated Universal Time (UTC) for the request. This is required when using shared key authorization.

xMsVersion string? (default ()) - Specifies the version of the REST protocol used for processing the request. This is required when using shared key authorization.

If the value is "getAccessControl" the access control list is returned in the response headers (Hierarchical Namespace must be enabled for the account), otherwise the properties are returned.

upn boolean? (default ()) - Optional. Valid only when Hierarchical Namespace is enabled for the account. If "true", the user identity values returned in the x-ms-owner, x-ms-group, and x-ms-acl response headers will be transformed from Azure Active Directory Object IDs to User Principal Names. If "false", the values will be returned as Azure Active Directory Object IDs. The default value is false. Note that group and application Object IDs are not translated because they do not have unique friendly names.

fsAction string? (default ()) - Required only for check access action. Valid only when Hierarchical Namespace is enabled for the account. File system operation read/write/execute in string form, matching regex pattern '[rwx-]{3}'

xMsLeaseId string? (default ()) - Optional. If this header is specified, the operation will be performed only if both of the following conditions are met: i) the path's lease is currently active and ii) the lease ID specified in the request matches that of the path.

ifMatch string? (default ()) - Optional. An ETag value. Specify this header to perform the operation only if the resource's ETag matches the value specified. The ETag must be specified in quotes.

ifNoneMatch string? (default ()) - Optional. An ETag value or the special wildcard ("*") value. Specify this header to perform the operation only if the resource's ETag does not match the value specified. The ETag must be specified in quotes.

ifModifiedSince string? (default ()) - Optional. A date and time value. Specify this header to perform the operation only if the resource has been modified since the specified date and time.

ifUnmodifiedSince string? (default ()) - Optional. A date and time value. Specify this header to perform the operation only if the resource has not been modified since the specified date and time.
