Apache Pegasus 2.2.0 is a feature release. The change-list is summarized here: https://github.com/apache/incubator-pegasus/issues/696.

Upgrading Notes

  • 2.2.0 can only be upgraded from 2.1.0. ReplicaServers of prior versions should upgrade to 2.1.0 firstly before upgrading to 2.2.0.

New Features

Modification of configs in runtime

In order to modify a configuration, we have to rolling-update all the servers to load the new config file. This is particularly cumbersome for us to operate the service.

Now, this feature allows us to update a config item using HTTP API. Please check XiaoMi/rdsn#719, XiaoMi/rdsn#704, XiaoMi/rdsn#682 for more details.
