# Supported data sources

Currently, Subsalt directly integrates with:

* MySQL
* Redshift
* Snowflake
* S3 (Parquet)
* Azure storage accounts (Parquet)
* Databricks
* Microsoft SQL Server

If your organization's data source is not listed here, don't worry! Subsalt can connect to any database that supports tabular structured data. Please reach out to the Subsalt team for more information on connecting to your database.

### Connecting to Parquet-based file systems

Subsalt automatically interprets each folder in the target directory as a potential table, with the data being nested in that folder. For example, if you have an S3 bucket called `my-bucket` that is structured like:

* **my-bucket**
  * **my-database**
    * 📁 **customers** <- "customers" will be a table
      * *file\_1.parquet* <- all files in this folder will be combined to make a single "customers" table
      * *file\_2.parquet*
      * *file\_3.parquet*
    * 📁 **product\_imgs** <- since this folder does not have any tabular data it will be ignored
      * *img1.png*
      * *img2.png*
    * 📁 **sales**
      * *file\_1.parquet*
      * *file\_2.parquet*
      * *file\_3.parquet*
      * *file\_4.parquet*

### Connecting to an S3 Bucket

When connecting to an S3 bucket, you will provide a URL; for the example above, the URL would look like this:

**S3 Bucket URL:** `s3://my-bucket/my-database/`

### Connecting to Azure storage

When connecting to an Azure storage account, you will provide a [connection string](https://learn.microsoft.com/en-us/azure/storage/common/storage-configure-connection-string) and a path.

For the example above the configuration would something look like this:

**Connection string:** `BlobEndpoint=https://my-bucket.blob.core.windows.net/;SharedAccessSignature=sv=2022-11-02&ss=b&srt=co&sp=rl&se=2024-10-19T05:27:46Z&st=2024-10-18T21:27:46Z&spr=https&sig=JTrgXgQNvbmPRXumK5rWChznHQRLdaUrTnCjCUmac44%3D`

**Path:** `my-database/`

## 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.subsalt.io/configuration/supported-data-sources.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.
