Status: WIP

Config could be provided in two ways:

• Environment variables e.g. SEND2KAFKA__HTTP__HOST=localhost
• YAML file, see the example in the next section
  • By default: a config.yaml file in current working directory
  • Could be overridden using SEND2KAFKA__CONFIG environment variable

NB: for Kafka attributes you need to use single _ instead of .: SEND2KAFKA__KAFKA__BOOTSTRAP_SERVERS=localhost:1234. Single underscores will be replaced with dots automatically. The configuration library uses dots as separators which conflicts with Kafka property format. In addition, environment variable names are not supposed to have dots.

There are default values provided in the snippet below:

http:
  host: 0.0.0.0
  port: 8080
  # num_workers: 0  # Optional. If not specified, it will be calculated automatically: https://actix.rs/docs/server/#multi-threading
kafka:
  bootstrap_servers: localhost:9092
  # Here you can provide additional Kafka parameters, for example:
  # sasl_mechanism: SCRAM-SHA-256
  # security_protocol: SASL_PLAINTEXT
  # sasl_username: me
  # sasl_password: mypassword

Sends a message to Kafka topic. Message payload should be provided as a message body. The message key could be specified using the optional X-Key HTTP header
