Yingjie Cao commented on FLINK-17572:
-------------------------------------

[~chesnay] Thanks for your comments and pointing out the REST API compatibility 
issue. What do you think if we only remove what is displayed in webui 
(including the constructor arguments you mentioned) and do not change the data 
structure returned by REST API?

> Remove checkpoint alignment buffered metric from webui
