Romain Hardouin commented on CASSANDRA-15301:
---------------------------------------------
Hi [~maxwellguo], here is what I understood:
1. You took a snapshot at time T
2. Snapshot data are exported
3. During the export you created a new table
4. You restored snapshotted data in a new cluster
5. You expected that new table data were part of the new, restored, cluster
The snapshot taken at time T only contains data created <= T, so you can't get
newer data.
I think I missed something, it's not clear to me what data have been exported.
When you need help regarding a process or a behavior you should use the "Users"
mailing list or Slack "cassandra" channel
