Metadata

This input adds the following metadata fields to each message:

  • kafka_key

  • kafka_topic

  • kafka_partition

  • kafka_offset

  • kafka_timestamp_unix

  • kafka_timestamp_ms

  • kafka_tombstone_message

  • kafka_offset_topic

  • kafka_offset_group

  • kafka_offset_partition

  • kafka_offset_commit_timestamp

  • kafka_offset_metadata

  • kafka_is_high_watermark

Fields

auto_replay_nacks

Whether messages that are rejected (nacked) at the output level should be automatically replayed indefinitely, eventually resulting in back pressure if the cause of the rejections is persistent. If set to false these messages will instead be deleted. Disabling auto replays can greatly improve memory efficiency of high throughput streams as the original shape of the data can be discarded immediately upon consumption and mutation.

Type: bool

Default: true

client_id

An identifier for the client connection.

Type: string

Default: benthos

conn_idle_timeout

The rough amount of time to allow connections to idle before they are closed.

Type: string

Default: 20s

metadata_max_age

The maximum age of metadata before it is refreshed. This interval also controls how frequently regex topic patterns are re-evaluated to discover new matching topics.

Type: string

Default: 5m

poll_interval

Duration between OffsetFetch polling attempts.

Type: string

Default: 15s

rack_id

A rack specifies where the client is physically located and changes fetch requests to consume from the closest replica as opposed to the leader replica.

Type: string

Default: ""

regexp_topics

Whether listed topics should be interpreted as regular expression patterns for matching multiple topics.

Type: bool

Default: false

request_timeout_overhead

The request time overhead. Uses the given time as overhead while deadlining requests. Roughly equivalent to request.timeout.ms, but grants additional time to requests that have timeout fields.

Type: string

Default: 10s

sasl[]

Specify one or more methods of SASL authentication. SASL is tried in order; if the broker supports the first mechanism, all connections will use that mechanism. If the first mechanism fails, the client will pick the first supported mechanism. If the broker does not support any client mechanisms, connections will fail.

Type: object

# Examples:
sasl:
  - mechanism: SCRAM-SHA-512
    password: bar
    username: foo

sasl[].aws

Contains AWS specific fields for when the mechanism is set to AWS_MSK_IAM.

Type: object

sasl[].aws.credentials

Optional manual configuration of AWS credentials to use. More information can be found in Amazon Web Services.

Type: object

sasl[].aws.credentials.from_ec2_role

Use the credentials of a host EC2 machine configured to assume an IAM role associated with the instance.

Type: bool

sasl[].aws.credentials.id

The ID of credentials to use.

Type: string

sasl[].aws.credentials.profile

A profile from ~/.aws/credentials to use.

Type: string

sasl[].aws.credentials.role

A role ARN to assume.

Type: string

sasl[].aws.credentials.role_external_id

An external ID to provide when assuming a role.

Type: string

sasl[].aws.credentials.secret

The secret for the credentials being used.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Manage Secrets before adding it to your configuration.

Type: string

sasl[].aws.credentials.token

The token for the credentials being used, required when using short term credentials.

Type: string

sasl[].aws.endpoint

Allows you to specify a custom endpoint for the AWS API.

Type: string

sasl[].aws.region

The AWS region to target.

Type: string

sasl[].extensions

Key/value pairs to add to OAUTHBEARER authentication requests.

Type: string

sasl[].mechanism

The SASL mechanism to use.

Type: string

Option Summary

AWS_MSK_IAM

AWS IAM based authentication as specified by the 'aws-msk-iam-auth' java library.

OAUTHBEARER

OAuth Bearer based authentication.

PLAIN

Plain text authentication.

SCRAM-SHA-256

SCRAM based authentication as specified in RFC5802.

SCRAM-SHA-512

SCRAM based authentication as specified in RFC5802.

none

Disable sasl authentication

sasl[].password

A password to provide for PLAIN or SCRAM-* authentication.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Manage Secrets before adding it to your configuration.

Type: string

Default: ""

sasl[].token

The token to use for a single session’s OAUTHBEARER authentication.

Type: string

Default: ""

sasl[].username

A username to provide for PLAIN or SCRAM-* authentication.

Type: string

Default: ""

seed_brokers[]

A list of broker addresses to connect to in order to establish connections. If an item of the list contains commas it will be expanded into multiple addresses.

Type: array

# Examples:
seed_brokers:
  - "localhost:9092"

  - "foo:9092"
  - "bar:9092"

  - "foo:9092,bar:9092"

tls

Custom TLS settings can be used to override system defaults.

Type: object

tls.client_certs[]

A list of client certificates to use. For each certificate either the fields cert and key, or cert_file and key_file should be specified, but not both.

Type: object

Default: []

# Examples:
client_certs:
  - cert: foo
    key: bar

  - cert_file: ./example.pem
    key_file: ./example.key

tls.client_certs[].cert

A plain text certificate to use.

Type: string

Default: ""

tls.client_certs[].cert_file

The path of a certificate to use.

Type: string

Default: ""

tls.client_certs[].key

A plain text certificate key to use.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Manage Secrets before adding it to your configuration.

Type: string

Default: ""

tls.client_certs[].key_file

The path of a certificate key to use.

Type: string

Default: ""

tls.client_certs[].password

A plain text password for when the private key is password encrypted in PKCS#1 or PKCS#8 format. The obsolete pbeWithMD5AndDES-CBC algorithm is not supported for the PKCS#8 format.

Because the obsolete pbeWithMD5AndDES-CBC algorithm does not authenticate the ciphertext, it is vulnerable to padding oracle attacks that can let an attacker recover the plaintext.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Manage Secrets before adding it to your configuration.

Type: string

Default: ""

# Examples:
password: foo
password: ${KEY_PASSWORD}

tls.enable_renegotiation

Default: false

tls.enabled

Type: bool

Default: false

tls.root_cas

An optional root certificate authority to use. This is a string, representing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Manage Secrets before adding it to your configuration.

Type: string

Default: ""

# Examples:
root_cas: |-
  -----BEGIN CERTIFICATE-----
  ...
  -----END CERTIFICATE-----

tls.root_cas_file

  - things.*

  - "foo,bar"
