## Async invocations

The connector can be configured to invoke function asynchronously. This lets you use [OpenFaaS async](https://docs.openfaas.com/reference/async/) features like retries.

To prevent the connector from consuming all Kafka messages at once and submitting them to the OpenFaaS async queue a limit on the number of inflight async invocations can be configured.

See the [Kafka connector README](https://github.com/openfaas/faas-netes/blob/master/chart/kafka-connector/README.md#async-invocations) to configure the connector for async invocations.
