[jira] [Commented] (CASSANDRA-15402) Make incremental backup
configurable per keyspace and table
[ https://issues.apache.org/jira/browse/CASSANDRA-15402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17378789#comment-17378789 ]

Thanks for your interest to the project and providing the initial patch version! I briefly checked it and I believe you have not yet come up with another patch version with "configure the table backup under the schema". Moreover, the patch is quite outdated. Are you still interested (and have enough time) in continuing this work? If yes, I'd propose to make a kind of design review: you document the structural changes you're going to make, then community validates the design, and then you start working on the code. I feel such a brief design review would be helpful to come up with the best solution and let you minimize re-work on your side.
If you have no time at the moment (which is totally fine!), let's remove assignee from the ticket, so someone else could potentially pick it up and move forward. Anyway, we need to change the status from "PATCH AVAILABLE" to smth else (IN PROGRESS or OPEN) because it assumes having the patch in the final stage.
PS:
I'm not a project committer, I'm just an enthusiast like you who is hanging around the project. I hope I was not rude and discouraging. It is always great to see people who are ready to dedicate their time to opensource projects.

> We know that when we do backup for cassandra, we can do full bakcup with snapshot, when we need to backup incremental data , incremental_backup can do some help .
> For snapshot we can just make snapshot for some keyspace/table. but incremental backup will do all data backup(make hard link for all sstable that flush from memtable or streaming ). we also know that commitlog's replay can do some keyspace /table 's filter.
> So I think for incremental backup we also need some filter for it.After all not all keyspace/table is so important to do backup.
