Optimize the availability of your clusters by configuring and tuning Redpanda cluster properties.
A malicious Kafka client application may create many network connections to execute its attacks. A poorly configured application may also create an excessive number of connections. To mitigate the risk of a client creating too many connections and using too many system resources, you can configure a Redpanda cluster to impose limits on the number of created client connections for its Kafka protocol server nodes.
The following cluster properties limit the number of connections:
kafka_connections_max: Similar to Kafka’s
max.connections, this property sets the maximum number of connections per broker.
kafka_connections_max_per_ip: Similar to Kafka’s
max.connections.per.ip, this property sets the maximum number of connections accepted per IP address by a broker.
Redpanda also provides properties to manage the rate of connection creation:
