After successful log-in, the following details will have to be entered,

* Storage Account
* File System

* Writeback File Name

The writeback creates a Parquet file in the data lake storage.&#x20;

**Partition Required:** If the Inforiver scenario is created and included in the writeback, and the user wants to writeback base and scenarios in separate parquet files, this is recommended.&#x20;

**Insert Variables:** Writeback file name can be customized using variables such as Execution ID and date time related IDs.

**Security:** Please note Inforiver leverages Azure Access Control Lists (ACLs) while configuring Azure Data Lake Storage as a writeback destination. That means the user is only shown folders and directories that they have access to as per the defined ACL rules.

### Roles

Ensure that the user has the permissions listed below.

In Inforiver managed mode:

1. Read on the storage account
2. Read and Execute on the file system

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.inforiver.com/working-with-inforiver/12.-data-writeback/destinations/azure-data-lake-storage.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
