Configuration Properties

Below you can find a list of configuration properties.

Name Default Description

Name	Default	Description
eureka.client.allow-redirects	`false`	Indicates whether server can redirect a client request to a backup server/cluster. If set to false, the server will handle the request directly, If set to true, it may send HTTP redirect to the client, with a new server location.
eureka.client.availability-zones		Gets the list of availability zones (used in AWS data centers) for the region in which this instance resides. The changes are effective at runtime at the next registry fetch cycle as specified by registryFetchIntervalSeconds.
eureka.client.backup-registry-impl		Gets the name of the implementation which implements BackupRegistry to fetch the registry information as a fallback option for only the first time when the eureka client starts. This may be needed for applications which needs additional resiliency for registry information without which it cannot operate.
eureka.client.cache-refresh-executor-exponential-back-off-bound	`10`	Cache refresh executor exponential back off related property. It is a maximum multiplier value for retry delay, in case where a sequence of timeouts occurred.
eureka.client.cache-refresh-executor-thread-pool-size	`2`	The thread pool size for the cacheRefreshExecutor to initialise with.
eureka.client.client-data-accept		EurekaAccept name for client data accept.
eureka.client.decoder-name		This is a transient config and once the latest codecs are stable, can be removed (as there will only be one).
eureka.client.disable-delta	`false`	Indicates whether the eureka client should disable fetching of delta and should rather resort to getting the full registry information. Note that the delta fetches can reduce the traffic tremendously, because the rate of change with the eureka server is normally much lower than the rate of fetches. The changes are effective at runtime at the next registry fetch cycle as specified by registryFetchIntervalSeconds
eureka.client.dollar-replacement	`_-`	Get a replacement string for Dollar sign <code>$</code> during serializing/deserializing information in eureka server.

eureka.client.eureka-server-connect-timeout-seconds	`5`	Indicates how long to wait (in seconds) before a connection to eureka server needs to timeout. Note that the connections in the client are pooled by {@link HttpClient} and this setting affects the actual connection creation and also the wait time to get the connection from the pool.
eureka.client.eureka-server-d-n-s-name		Gets the DNS name to be queried to get the list of eureka servers.This information is not required if the contract returns the service urls by implementing serviceUrls. The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
eureka.client.eureka-server-port		Gets the port to be used to construct the service url to contact eureka server when the list of eureka servers come from the DNS.This information is not required if the contract returns the service urls eurekaServerServiceUrls(String). The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.

eureka.client.eureka-server-u-r-l-context		Gets the URL context to be used to construct the service url to contact eureka server when the list of eureka servers come from the DNS. This information is not required if the contract returns the service urls from eurekaServerServiceUrls. The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
eureka.client.eureka-service-url-poll-interval-seconds	`300`	Indicates how often(in seconds) to poll for changes to eureka server information. Eureka servers could be added or removed and this setting controls how soon the eureka clients should know about it.
eureka.client.fetch-registry	`true`	Indicates whether this client should fetch eureka registry information from eureka server.
eureka.client.fetch-remote-regions-registry		Comma separated list of regions for which the eureka registry information will be fetched. It is mandatory to define the availability zones for each of these regions as returned by availabilityZones. Failing to do so, will result in failure of discovery client startup.
eureka.client.filter-only-up-instances	`true`	Indicates whether to get the applications after filtering the applications for instances with only InstanceStatus UP states.
eureka.client.g-zip-content	`true`	Indicates whether the content fetched from eureka server has to be compressed whenever it is supported by the server. The registry information from the eureka server is compressed for optimum network traffic.

eureka.client.log-delta-diff	`false`	Indicates whether to log differences between the eureka server and the eureka client in terms of registry information. Eureka client tries to retrieve only delta changes from eureka server to minimize network traffic. After receiving the deltas, eureka client reconciles the information from the server to verify it has not missed out some information. Reconciliation failures could happen when the client has had network issues communicating to server.If the reconciliation fails, eureka client gets the full registry information. While getting the full registry information, the eureka client can log the differences between the client and the server and this setting controls that. The changes are effective at runtime at the next registry fetch cycle as specified by registryFetchIntervalSecondsr
eureka.client.on-demand-update-status-change	`true`	If set to true, local status updates via ApplicationInfoManager will trigger on-demand (but rate limited) register/updates to remote eureka servers.

When the DNS name is updated to have additional servers, that information is used immediately after the eureka client polls for that information as specified in eurekaServiceUrlPollIntervalSeconds. Alternatively, the service urls can be returned serviceUrls, but the users should implement their own mechanism to return the updated list in case of changes. The changes are effective at runtime.
