-|===
-|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.enabled | `+++true+++` | Flag to indicate that the Eureka client is enabled.
-|eureka.client.encoder-name |  | This is a transient config and once the latest codecs are stable, can be removed (as there will only be one).
-|eureka.client.escape-char-replacement | `+++__+++` | Get a replacement string for underscore sign <code>_</code> during serializing/ deserializing information in eureka server.
-|eureka.client.eureka-connection-idle-timeout-seconds | `+++30+++` | Indicates how much time (in seconds) that the HTTP connections to eureka server can stay idle before it can be closed. In the AWS environment, it is recommended that the values is 30 seconds or less, since the firewall cleans up the connection information after a few mins leaving the connection hanging in limbo.
-|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-read-timeout-seconds | `+++8+++` | Indicates how long to wait (in seconds) before a read from eureka server needs to timeout.
-|eureka.client.eureka-server-total-connections | `+++200+++` | Gets the total number of connections that is allowed from eureka client to all eureka servers.
-|eureka.client.eureka-server-total-connections-per-host | `+++50+++` | Gets the total number of connections that is allowed from eureka client to a eureka server host.
-|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 | `+++0+++` | 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.healthcheck.enabled | `+++true+++` | Enables the Eureka health check handler.
-|eureka.client.heartbeat-executor-exponential-back-off-bound | `+++10+++` | Heartbeat 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.heartbeat-executor-thread-pool-size | `+++2+++` | The thread pool size for the heartbeatExecutor to initialise with.
-|eureka.client.initial-instance-info-replication-interval-seconds | `+++40+++` | Indicates how long initially (in seconds) to replicate instance info to the eureka server.
-|eureka.client.instance-info-replication-interval-seconds | `+++30+++` | Indicates how often(in seconds) to replicate instance changes to be replicated to the eureka server.
-|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.
-|eureka.client.order | `+++0+++` | Order of the discovery client used by `CompositeDiscoveryClient` for sorting available clients.
-|eureka.client.prefer-same-zone-eureka | `+++true+++` | Indicates whether or not this instance should try to use the eureka server in the same zone for latency and/or other reason. Ideally eureka clients are configured to talk to servers in the same zone The changes are effective at runtime at the next registry fetch cycle as specified by registryFetchIntervalSeconds
-|eureka.client.property-resolver |  | 
-|eureka.client.proxy-host |  | Gets the proxy host to eureka server if any.
-|eureka.client.proxy-password |  | Gets the proxy password if any.
-|eureka.client.proxy-port |  | Gets the proxy port to eureka server if any.
-|eureka.client.proxy-user-name |  | Gets the proxy user name if any.

-`EurekaClient` uses either `RestTemplate`, `WebClient` or `JerseyClient` under the hood. In order to use the `EurekaClient`, you need to have one of the supported HTTP clients on your classpath.

-To use `RestTemplate`, add `spring-boot-starter-web` to your dependencies. To use `WebClient`, add `spring-boot-starter-webflux` to your dependencies. If both `RestTemplate` and `WebClient` are on the classpath when `eureka.client.webclient.enabled` is set to `true`, `WebClient` is used. Otherwise, `RestTemplate` is used.
