com.netflix.appinfo.LeaseInfo

public class LeaseInfo
extends java.lang.Object

Represents the lease information with Eureka.

Eureka decides to remove the instance out of its view depending on the duration that is set in EurekaInstanceConfig.getLeaseExpirationDurationInSeconds() which is held in this lease. The lease also tracks the last time it was renewed.

LeaseInfo

public LeaseInfo(int renewalIntervalInSecs,
                 int durationInSecs,

TODO: note about renewalTimestamp legacy: The previous change to use Jackson ser/deser changed the field name for lastRenewalTimestamp to renewalTimestamp for serialization, which causes an incompatibility with the jacksonNG codec when the server returns data with field renewalTimestamp and jacksonNG expects lastRenewalTimestamp. Remove this legacy field from client code in a few releases (once servers are updated to a release that generates json with the correct lastRenewalTimestamp).
