| config | Consumer behavior | AdminClient behavior | Description |
|---|---|---|---|
client.dns.lookup, bootstrap.servers | use ClientUtils.parseAndValidateAddresses to get InetSocketAddress of broker, and to sendMedatataRequest to the broker. | use ClientUtils.parseAndValidateAddresses to get InetSocketAddress of broker, and to send MedatataRequest to the broker. | Both clients will take the same action |
| default.api.timeout.ms | The consumer will retry until the timeout is reached | The AdminClient will retry until the timeout is reached or the number of retries exceeds the limit | AdminClient does the same with Consumer since the default of `retries` is In Integer.MaxValue and have the same default timeout value |
| request.timeout.ms | Used by NetworkClient for individual rpcs to await acknowledgment from servers | Used by KafkaAdminClient to decide whether each and the timeout for NetworkClient is 3600000 | There is a small difference wheras the result are the same. |
send.buffer.bytes, receive.buffer.bytes, | Used to construct NetworkClient | Used to construct NetworkClient | Both clients will take the same action |
The amount of time to wait before attempting to retry a failed ListOffsetsRequest rpc and MetadataRequest rpc | The amount of time to wait before attempting to retry a failed ListOffsetsRequest rpc and MetadataRequest rpc | Both clients will take the same action | |
| just an identifier and are hardcoded to GetOffsetShell | just an identifier and are hardcoded to GetOffsetShell | Both clients will take the same actionhave no impact | |
The period of time to evict metadata cache for `ConsumerMetadata` | The period of time to evict metadata cache for `AdminMetadataManager` | There may be difference in implementation details, the metadata cache will have the same expire time. | |
metric.reporters, and all other metric releated configs | Used to get client metrics | Used to get client metricshave no impact | Both clients will take the same action |
security.protocol, and all other security related configs | Used to establish security connection | Used to establish security connection | Both clients will take the same action |
| retries | Consumer will retries until default.api.timeout.ms is reached | default value is Integer.MaxValue | The AdminClient will act the same with Consumer by default, and we can set a config to control how many times we can retry |
