**Type:** Output ▼

[Output](https://docs.redpanda.com/cloud-data-platform/develop/connect/components/outputs/azure_blob_storage/)[Input](https://docs.redpanda.com/cloud-data-platform/develop/connect/components/inputs/azure_blob_storage/)

**Available in:** Cloud, [Self-Managed](https://docs.redpanda.com/connect/components/outputs/azure_blob_storage/%20%22View%20the%20Self-Managed%20version%20of%20this%20component%22)

Sends message parts as objects to an Azure Blob Storage Account container. Each object is uploaded with the filename specified with the `container` field.

#### Common

```yml
outputs:
  label: ""
  azure_blob_storage:
    storage_account: ""
    storage_access_key: ""
    storage_connection_string: ""
    storage_sas_token: ""
    container: "" # No default (required)
    path: ${!counter()}-${!timestamp_unix_nano()}.txt
    max_in_flight: 64
```

#### Advanced

```yml
outputs:
  label: ""
  azure_blob_storage:
    storage_account: ""
    storage_access_key: ""
    storage_connection_string: ""
    storage_sas_token: ""
    container: "" # No default (required)
    path: ${!counter()}-${!timestamp_unix_nano()}.txt
    blob_type: BLOCK
    public_access_level: PRIVATE
    max_in_flight: 64
```

In order to have a different path for each object you should use function interpolations described [here](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries), which are calculated per message of a batch.

Supports multiple authentication methods but only one of the following is required:

-   `storage_connection_string`

-   `storage_account` and `storage_access_key`

-   `storage_account` and `storage_sas_token`

-   `storage_account` to access via [DefaultAzureCredential](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity#DefaultAzureCredential)


If multiple are set then the `storage_connection_string` is given priority.

If the `storage_connection_string` does not contain the `AccountName` parameter, please specify it in the `storage_account` field.

## [](#performance)Performance

This output benefits from sending multiple messages in flight in parallel for improved performance. You can tune the max number of in flight messages (or message batches) with the field `max_in_flight`.

## [](#fields)Fields

### [](#blob_type)`blob_type`

Block and Append blobs are comprized of blocks, and each blob can support up to 50,000 blocks. The default value is ``"`BLOCK`"``.\` This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).

**Type**: `string`

**Default**: `BLOCK`

**Options**: `BLOCK`, `APPEND`

### [](#container)`container`

The container for uploading the messages to. This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).

**Type**: `string`

```yaml
# Examples:
container: messages-${!timestamp("2006")}
```

### [](#max_in_flight)`max_in_flight`

The maximum number of messages to have in flight at a given time. Increase this to improve throughput.

**Type**: `int`

**Default**: `64`

### [](#path)`path`

The path of each message to upload. This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).

**Type**: `string`

**Default**: `${!counter()}-${!timestamp_unix_nano()}.txt`

```yaml
# Examples:
path: ${!counter()}-${!timestamp_unix_nano()}.json

# ---

path: ${!meta("kafka_key")}.json

# ---

path: ${!json("doc.namespace")}/${!json("doc.id")}.json
```

### [](#public_access_level)`public_access_level`

The container’s public access level. The default value is `PRIVATE`. This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).

**Type**: `string`

**Default**: `PRIVATE`

**Options**: `PRIVATE`, `BLOB`, `CONTAINER`

### [](#storage_access_key)`storage_access_key`

The storage account access key. This field is ignored if `storage_connection_string` is set.

**Type**: `string`

**Default**: `""`

### [](#storage_account)`storage_account`

The storage account to access. This field is ignored if `storage_connection_string` is set.

**Type**: `string`

**Default**: `""`

### [](#storage_connection_string)`storage_connection_string`

A storage account connection string. This field is required if `storage_account` and `storage_access_key` / `storage_sas_token` are not set.

**Type**: `string`

**Default**: `""`

### [](#storage_sas_token)`storage_sas_token`

The storage account SAS token. This field is ignored if `storage_connection_string` or `storage_access_key` are set.

**Type**: `string`

**Default**: `""`
