@sensejs/kafkajs-standalone v0.11.0

Standalone Wrapper for KafkaJS

This package provides easy to use kafka consumer and producer based on kafkajs, without core parts of sense.js as dependencies.

Install

npm install @sensejs/kafkajs-standalone kafkajs

Highlights:

• Consumer:

  1. Automatically set partitionConsumedConcurrently to number of partitions of a topic, to maximum the throughput.

  2. Detect rebalance as quickly as possible.

  3. Save offset when consumer group is going to rebalance, to avoid any message be re-consumed as possible as it can (while still you should not expect it won't happen).

• Producer:

  1. Default maxInFlightRequests to 1 and idempotent to true, to fit requirements of transactional producer. Can be overridden if transaction is not required.

  2. Ability to provide messageKeyProvider to assign a key to message if not specified.
