[jira] [Commented] (CASSANDRA-12106) Add ability to blocklist / denylist a CQL partition so all requests are ignored

["Stefan Miklosovic (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-12106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17613504#comment-17613504 ] 

Stefan Miklosovic commented on CASSANDRA-12106:
-----------------------------------------------

Would it be interesting for people to have auto-deny capability? It would autodeny partitions which are logged as too big upon writing sstables to disk. Until new sstable is written, it would still accept these big rows but as soon as BigTableWriter realises it is too large, why not to autodeny it so that partition will never be written again?

the very early POC is here

> Sometimes reads/writes to a given partition may cause problems due to the data present. It would be useful to have a manual way to blocklist / denylist
>  such partitions so all read and write requests to them are rejected.
