Hi,

I am trying to understand the Flink 1.10 savepoints related 
documentation<https://ci.apache.org/projects/flink/flink-docs-release-1.10/ops/state/savepoints.html#triggering-savepoints>
 that mentions -
“When triggering a savepoint, a new savepoint directory is created where the 
data as well as the meta data will be stored.”

However, I came across this issue - 
https://issues.apache.org/jira/browse/FLINK-5763 which mentions the problem -
“For file system based checkpoints (FsStateBackend, RocksDBStateBackend) this 
results in the savepoint referencing files from the checkpoint directory 
(usually different than <target>)”

My understanding of the issue is that savepoints were not storing the data and 
were pointing to checkpoints for actual state data.
The issue has been fixed and changes made into Flink 1.11.

But, I would like to get the behavior for Flink 1.10 confirmed.

Does savepoint in Flink 1.10 store both the data & metadata? OR it has 
references to checkpoints & need access to checkpoints directory to restore 
state?

Thanks much,
Abhinav Bajaj
