    • bootstrapServers

      public T bootstrapServers(List<String> value)
      Description copied from interface: CommonClientConfigFields

      bootstrap.servers

      A list of host/port pairs to use for establishing the initial connection to the Kafka cluster.
      The client will make use of all servers irrespective of which servers are specified here for bootstrapping—this list only impacts the initial hosts used to discover the full set of servers.
      This list should be in the form host1:port1,host2:port2,....
      Since these servers are just used for the initial connection to discover the full cluster membership (which may change dynamically), this list need not contain the full set of servers (you may want more than one, though, in case a server is down).

      The default is 'TLSv1.3' when running with Java 11 or newer, 'TLSv1.2' otherwise.
      This value should be fine for most use cases.
      Allowed values in recent JVMs are 'TLSv1.2' and 'TLSv1.3'.
      'TLS', 'TLSv1.1', 'SSL', 'SSLv2' and 'SSLv3' may be supported in older JVMs, but their usage is discouraged due to known security vulnerabilities.
      With the default value for this config and 'ssl.enabled.protocols', clients will downgrade to 'TLSv1.2' if the server does not support 'TLSv1.3'.
      If this config is set to 'TLSv1.2', clients will not use 'TLSv1.3' even if it is one of the values in ssl.enabled.protocols and the server only supports 'TLSv1.3'.

      Default: TLSv1.3

      The list of protocols enabled for SSL connections.
      The default is 'TLSv1.2,TLSv1.3' when running with Java 11 or newer, 'TLSv1.2' otherwise.
      With the default value for Java 11, clients and servers will prefer TLSv1.3 if both support it and fallback to TLSv1.2 otherwise (assuming both support at least TLSv1.2).
      This default should be fine for most cases.

      However, the broker polls the URL every sasl.oauthbearer.jwks.endpoint.refresh.ms milliseconds to refresh the cache with any forthcoming keys before any JWT requests that include them are received.
      If the URL is file-based, the broker will load the JWKS file from a configured location on startup.

      If there is no match, the broker will reject the JWT and authentication will fail.
