reachfh / brod_group_subscriber_example

Example Elixir app which uses brod_group_subscriber to consume Kafka messages

brod_group_subscriber_example

Installation

Kafka:

brew install kafka
brew services start zookeeper
brew services start kafka

Generate a Kafka message from Elixir console:

:brod.produce_sync_offset(:client1, "foo", :random, "the key", "the value")

TODO

• Extract trace context from message kafka headers and use in dlc send

• Use link?

• service.name is wrong Set service.name in span?

  # {"service.name", @app},
  # {"peer.service", @app},
  

• Log time is wrong (very large)

• set_status is not working?

• Use retries for error handling

• Maybe sleep

start_time = System.monotonic_time()
result = process_message(message, state)
processing_duration = System.monotonic_time() - start_time
