azure_blob_storage

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

Introduced in version 3.36.0.

In order to have a different path for each object you should use function interpolations described here, 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

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

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

blob_type

Block and Append blobs are made up of blocks, and each blob can support up to 50,000 blocks. The default value is BLOCK.

This field supports interpolation functions.

Type: string

Default: BLOCK

Options: BLOCK, APPEND

container

The container for uploading the messages to.

This field supports interpolation functions.

Type: string

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

max_in_flight

The maximum number of messages to have in flight at a given time. For outputs that send messages in batches, this limit applies to message batches. Increase this value to improve throughput.

Type: int

Default: 64

path

The path of each message to upload.

This field supports interpolation functions.

Type: string

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

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

# ---

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

# ---

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

public_access_level

The container’s public access level. The default value is PRIVATE.

This field supports interpolation functions.

Type: string

Default: PRIVATE

Options: PRIVATE, BLOB, CONTAINER

storage_access_key

The access key for the storage account. Use this field along with storage_account for authentication. This field is ignored when the storage_connection_string field is populated.

Type: string

Default: ""

storage_account

The storage account to access. This field is ignored when the storage_connection_string field is populated, unless the connection string does not contain the AccountName parameter.

Type: string

Default: ""

storage_connection_string

The connection string for the storage account. This field is required if storage_account is not set.

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

Type: string

Default: ""

storage_sas_token

The SAS token for the storage account. Use this field along with storage_account for authentication. This field is ignored when either the storage_connection_string or storage_access_key fields are populated.

Type: string

Default: ""
