Kaffe.Producer (Kaffe v1.21.0) View Source
The producer pulls in values from the Kaffe producer configuration:
heroku_kafka_env
- endpoints and SSL configuration will be pulled from ENVendpoints
- plaintext Kafka endpointstopics
- a list of Kafka topics to prep for producingpartition_strategy
- the strategy to use when selecting the next partition. Default:md5
.:md5
: provides even and deterministic distrbution of the messages over the available partitions based on an MD5 hash of the key:random
- Select a random partition- function - Pass a function as an argument that accepts five arguments and
returns the partition number to use for the message
topic, current_partition, partitions_count, key, value
Clients can also specify a partition directly when producing.
Currently only synchronous production is supported.

This is a simpler way to produce if you've only given Producer a single topic for production and don't want to specify the topic for each call.
Returns:
* `:ok` on successfully producing the message
* `{:error, reason}` for any error
