It would be the same as with any other form of async checkpointing. No
direct blocking of processing but the network traffic might indirectly
affect it to some extent :)

If the checkpointing to Ceph happens asynchronously, does it still have any
impact on the stream processing?

Hi,
To my understanding Ceph as in http://ceph.com/ceph-storage/ is a block
based object storage system. You can use it mounted to your server and will
behave as a local file system to most extent but will be shared in the
cluster.
The performance might not be as good as with HDFS to our experie
Hi,
Flink documents suggests that Ceph can be used as a persistent storage for
states.
https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/stream/checkpointing.html
Considering that Ceph is a transactional database, wouldn't it have adverse
effect on Flink's performance?
