Eureka customers will send a heartbeat every 30 seconds to renew the contract.

Normally, if Eureka Server does not receive a renewal from the Eureka customer within 90 seconds, it removes the instance from its registry.

It is not recommended to change the renewal interval.

The Eureka client gets the registry information from the server and caches it locally.

The registration list information is updated periodically (every 30 seconds).

If, for some reason, the registration list information does not match in time, the Eureka client will retrieve the entire registry information.

Self-protection mode

If at any time, Eureka Serve receives a renewal that is less than the percentage configured for that value (the default is less than 85% within 15 minutes)

Then the server turns on self-protection mode, that is, it no longer removes the information from the registration list.

This is the end of the introduction to the principles of Eureka. Thank you for your reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
