nanomsg

Consumes messages via Nanomsg sockets (scalability protocols).

Common

# Common config fields, showing default values
input:
  label: ""
  nanomsg:
    urls: [] # No default (required)
    bind: true
    socket_type: PULL
    auto_replay_nacks: true
    sub_filters: []

Advanced

# All config fields, showing default values
input:
  label: ""
  nanomsg:
    urls: [] # No default (required)
    bind: true
    socket_type: PULL
    auto_replay_nacks: true
    sub_filters: []
    poll_timeout: 5s

Currently only PULL and SUB sockets are supported.

Fields

urls

A list of URLs to connect to (or as). If an item of the list contains commas it will be expanded into multiple URLs.

Type: array

bind

Whether the URLs provided should be connected to, or bound as.

Type: bool
Default: true

socket_type

The socket type to use.

Type: string
Default: "PULL"
Options: PULL, SUB.

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

sub_filters

A list of subscription topic filters to use when consuming from a SUB socket. Specifying a single sub_filter of '' will subscribe to everything.

Type: array
Default: []

poll_timeout

The period to wait until a poll is abandoned and reattempted.

Type: string
Default: "5s"
