Hi,
this is a design investigation.
On many docker containers, we will have **Filebeat** that reads logs (generated by many services).
On one docker container we will have **Elasticsearch** that receives and indexes the logs.
We will have **Kafka** in one docker container for other purpose.
1. Do we have advantages to let **Kafka** collect logs from the docker containers with **Filebeat** and forward them to the **Elasticsearch** container ?
2. The **Filebeat** uses a backpressure-sensitive protocol when sending data to Elasticsearch. Won't we loose this advantage by putting **Kafka** in the middle ?
Thanks for your answers,
Yves
