Field Detail

ALL_TOPIC_CONFIG_SYNONYMS

public static final Map<String,List<ConfigSynonym>> ALL_TOPIC_CONFIG_SYNONYMS

Maps topic configurations to their equivalent broker configurations. Topics can be configured either by setting their dynamic topic configurations, or by setting equivalent broker configurations. For historical reasons, the equivalent broker configurations have different names. This table maps each topic configuration to its equivalent broker configurations. In some cases, the equivalent broker configurations must be transformed before they can be used. For example, log.roll.hours must be converted to milliseconds before it can be used as the value of segment.ms. The broker configurations will be used in the order specified here. In other words, if both the first and the second synonyms are configured, we will use only the value of the first synonym and ignore the second.

TOPIC_CONFIG_SYNONYMS

public static final Map<String,String> TOPIC_CONFIG_SYNONYMS

Map topic config to the server config with the highest priority. Some of these have additional synonyms that can be obtained using [[kafka.server.DynamicBrokerConfig#brokerConfigSynonyms]] or using [[AllTopicConfigSynonyms]]
