# Rabbitmq

> Rabbitmq sink connector

## Description

Used to write data to Rabbitmq.

## Key features

- [ ] [exactly-once](../../concept/connector-v2-features.md)
- [ ] [schema projection](../../concept/connector-v2-features.md)

## Options

| name | type | required | default value |
|-----------------------------|---------|----------|---------------|
| host | string | yes | - |
| port | int | yes | - |
| virtual_host | string | yes | - |
| username | string | yes | - |
| password | string | yes | - |
| queue_name | string | yes | - |

### host [string]

the default host to use for connections

### port [int]

the default port to use for connections

### virtual_host [string]

virtual host – the virtual host to use when connecting to the broker

### username [string]

the AMQP user name to use when connecting to the broker

### password [string]

the password to use when connecting to the broker

### url [string]

convenience method for setting the fields in an AMQP URI: host, port, username, password and virtual host

### queue_name [string]

the queue to write the message to

### schema [Config]

#### fields [Config]

the schema fields of upstream data.

### network_recovery_interval [string]

how long will automatic recovery wait before attempting to reconnect, in ms

### topology_recovery [string]

if true, enables topology recovery

### automatic_recovery [string]

if true, enables connection recovery

### connection_timeout [int]

connection TCP establishment timeout in milliseconds; zero for infinite

## Example

simple:

```hocon
sink {
RabbitMQ {
host = "rabbitmq-e2e"
port = 5672
virtual_host = "/"
username = "guest"
password = "guest"
queue_name = "test1"
}
}

# Rabbitmq

> Rabbitmq source connector

## Description

Used to read data from Rabbitmq.

## Key features

- [ ] [batch](../../concept/connector-v2-features.md)
531651225 marked this conversation as resolved.
Show resolved Hide resolved
- [x] [stream](../../concept/connector-v2-features.md)
- [x] [exactly-once](../../concept/connector-v2-features.md)
- [x] [schema projection](../../concept/connector-v2-features.md)
- [ ] [parallelism](../../concept/connector-v2-features.md)
- [ ] [support user-defined split](../../concept/connector-v2-features.md)

:::tip
The source must be non-parallel (parallelism set to 1) in order to achieve exactly-once. This limitation is mainly due to RabbitMQ’s approach to dispatching messages from a single queue to multiple consumers.
