Hi Priya and Vincent
Thank you for your reply!
It looks the new feature is implemented only in the latest version.
But I'm using Spark 2.3.0 so, in my understanding, I need to stop and
reload apps.
Thanks

Changes in streaming query that allow or disallow recovery from

Checkpointing is only used for failure recovery not for app
upgrades. You need to manually code the unload/load and save it
to a persistent store

Using checkpointing for graceful updates is my understanding
as well, based on the writeup in
https://spark.apache.org/docs/latest/structured-streaming-programming-guide.html#recovering-from-failures-with-checkpointing,
and some prototyping. Have you faced any missed events?

Hi
Now I'm trying to update my structured streaming
application.
But I have no idea how to update it gracefully.
Should I stop it, replace a jar file then restart it?
In my understanding, in that case, all the state will be
recovered if I
use checkpoints.
Is this correct?
Thank you,
