Fields

`seed_brokers`

A list of broker addresses to connect to. Use commas to separate multiple addresses in a single list item.

Type: array

# Examples

seed_brokers:
  - localhost:9092

seed_brokers:
  - foo:9092
  - bar:9092

seed_brokers:
  - foo:9092,bar:9092

yml

`client_id`

An identifier for the client connection.

Type: string

Default: benthos

`tls`

Override system defaults with custom TLS settings.

Type: object

`tls.enabled`

Whether custom TLS settings are enabled.

Type: bool

Default: false

`tls.skip_cert_verify`

Whether to skip server-side certificate verification.

Type: bool

Default: false

`tls.enable_renegotiation`

Whether to allow the remote server to repeatedly request renegotiation. Enable this option if you’re seeing the error message local error: tls: no renegotiation.

Type: bool

Default: false

`tls.root_cas`

Specify a certificate authority to use (optional). This is a string that represents a certificate chain from the parent-trusted root certificate, through 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-----

yml

`tls.root_cas_file`

Specify the path to a root certificate authority file (optional). This is a file, often with a .pem extension, which contains a certificate chain from the parent-trusted root certificate, through possible intermediate signing certificates, to the host certificate.

Type: string

Default: ""

# Examples

root_cas_file: ./root_cas.pem

yml

`tls.client_certs`

A list of client certificates to use. For each certificate, specify values for either the cert and key, or cert_file and key_file fields.

Type: array

Default: []

# Examples

client_certs:
  - cert: foo
    key: bar

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

yml

`tls.client_certs[].cert`

A plain text 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[].cert_file`

The path of a certificate to use.

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.

The pbeWithMD5AndDES-CBC algorithm does not authenticate ciphertext, and is vulnerable to padding Oracle attacks which may allow an attacker recover the plain text password.

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}

yml

`sasl`

Specify one or more methods of SASL authentication, which are attempted in order. If the broker supports the first mechanism, all connections use that mechanism. If the first mechanism fails, the client picks the first supported mechanism. Connections fail if the broker does not support any client mechanisms.

Type: array

# Examples

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

yml

`sasl[].mechanism`

The SASL mechanism to use.

Type: string

`sasl[].aws.credentials.role_external_id`

An external ID to provide when assuming a role.

Type: string

Default: ""

metadata_max_age

The maximum period of time (in minutes) after which metadata is refreshed.

Type: string

Default: 5m

`topics`

A list of topics to consume from. Use commas to separate multiple topics in a single element.

When a consumer_group is specified, partitions are automatically distributed across consumers of a topic. Otherwise, all partitions are consumed.

Alternatively, you can specify explicit partitions to consume by using a colon after the topic name. For example, foo:0 would consume the partition 0 of the topic foo. This syntax supports ranges. For example, foo:0-10 would consume partitions 0 through to 10 inclusive.

It is also possible to specify an explicit offset to consume from by adding another colon after the partition. For example, foo:0:10 would consume the partition 0 of the topic foo starting from the offset 10. If the offset is not present (or remains unspecified) then the field start_from_oldest determines which offset to start from.

Type: array

# Examples

topics:
  - foo
  - bar

topics:
  - things.*

topics:
  - foo,bar

yml

`regexp_topics`

Whether listed topics are interpreted as regular expression patterns for matching multiple topics. When topics are specified with explicit partitions, this field must remain set to false.

Type: bool

Default: false

`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: ""

`consumer_group`

An optional consumer group. When this value is specified:

The partitions of any topics, specified in the topics field, are automatically distributed across consumers sharing a consumer group
Partition offsets are automatically committed and resumed under this name

Consumer groups are not supported when you specify explicit partitions to consume from in the topics field.

Type: string

`commit_period`

The period of time between each commit of the current partition offsets. Offsets are always committed during shutdown.

Type: string

Default: 5s

`partition_buffer_bytes`

A buffer size (in bytes) for each consumed partition, which allows the internal queuing of records before they are flushed. Increasing this value may improve throughput but results in higher memory utilization.

Each buffer can grow slightly beyond this value.

Type: string

Default: 1MB

`topic_lag_refresh_period`

The interval between refresh cycles. During each cycle, this input queries the Repanda Connect server to calculate the topic lag - the number of produced messages that remain to be read from each topic/partition pair by the specified consumer group.

Type: string

Default: 5s

`auto_replay_nacks`

Whether to automatically replay messages that are rejected (nacked) at the output level. If the cause of rejections is persistent, leaving this option enabled can result in back pressure.

Set auto_replay_nacks to false to delete rejected messages. Disabling auto replays can greatly improve memory efficiency of high throughput streams, as the original shape of the data is discarded immediately upon consumption and mutation.

Type: bool

Default: true
