>                 URL: https://issues.apache.org/jira/browse/FLINK-22797
>             Project: Flink
>          Issue Type: Improvement
>          Components: Documentation, Runtime / State Backends

> Information on incremental checkpoints is somewhat scattered and hard to find 
> in the documentation. In particular, the main page on checkpoints [1] should 
> contain at least a short description of incremental checkpoints. They are 
> currently mentioned in only one sentence, without any further explanation.
> A very short summary with a link to the RocksDB section [2] would suffice, 
> since they are specific to that state backend.
> They are also mentioned on the config pages [3 and 4], which likewise contain 
> incomplete information and no link ("may not be supported by every state 
> backend").
> One basically has to follow the above clues and deduce that there may be more 
> information in the state backends section.
