----------------------------------------
Summary: Improve incremental checkpoints documentation
Key: FLINK-22797
URL: https://issues.apache.org/jira/browse/FLINK-22797
Project: Flink
Issue Type: Improvement
Components: Documentation, Runtime / Checkpointing
Reporter: Nicolaus Weidner
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.
