Multi-Cluster Configuration – Operatr for Apache Kafka®

One instance of Operatr can manage multiple Apache Kafka clusters in accordance with the Cluster Credits of your license.

Notes on the Multi-Cluster function:

Multi-cluster does not mean multi-region. Operatr must be installed within a reasonably low latency network to your Cluster(s).
When configuring multiple clusters, the first configured cluster is your primary cluster.
The primary cluster holds your Operatr metrics, snapshots, and audit log. You can switch the primary cluster at any time.

Configuration example:

To configure multiple clusters, simply repeat the connection configuration with _2, _3, _4 suffixes:

# Cluster 1, Vanilla Apache Kafka
ENVIRONMENT_NAME=Trade Book (Staging)
BOOTSTRAP=kafka-1:19092,kafka-2:19093,kafka-3:19094
SECURITY_PROTOCOL=SASL_PLAINTEXT
SASL_MECHANISM=PLAIN
SASL_JAAS_CONFIG=org.apache.kafka.common.security.plain.PlainLoginModule required username="admin" password="admin-secret";

# Cluster 2, Confluent Cloud
ENVIRONMENT_NAME_2=Outbound Payments (Staging)
BOOTSTRAP_2=pkc-1234.us-east-1.aws.confluent.cloud:9092
SECURITY_PROTOCOL_2=SASL_SSL
