No

Array of strings

You can manually specify IPv4 private IP addresses when creating an instance.

The number of specified private IP addresses must be equal to or less than the number of created brokers.

If the number of specified private IP addresses is less than the number of created brokers, the system automatically assigns private IP addresses to the remaining brokers.

String

Security protocol to use after SASL is enabled.

  • SASL_SSL: Data is encrypted with SSL certificates for high-security transmission.

  • SASL_PLAINTEXT: Data is transmitted in plaintext with username and password authentication.

If this parameter is left blank, SASL_SSL authentication is enabled by default. This parameter cannot be manually modified once the instance is created.

If the port_protocol parameter were used in instance creation, its value is used for the private and public network access security protocols and this parameter becomes invalid.

sasl_enabled_mechanisms

No

Array of strings

Authentication mechanism to use after SASL is enabled. This parameter is mandatory if SASL authentication is enabled (ssl_enable=true).

If this parameter is left blank, PLAIN authentication is enabled by default.
