C. Scott Andreas updated CASSANDRA-13290:
    Component/s: Repair

> Optimizing very small repair streams
> ------------------------------------
>                 Key: CASSANDRA-13290
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13290
>             Project: Cassandra
>          Issue Type: Improvement
>          Components: Repair
>            Reporter: Benjamin Roth
>            Priority: Major
> I often encountered repair scenarios, where a lot of tiny repair streams were 
> created. This results in hundrets, thousands or even ten-thousands super 
> small SSTables (some bytes to some kbytes).
> This puts a lot of pressure on compaction and may even lead to a crash due to 
> too many open files - I also encountered this.
> What could help to avoid this:
> After CASSANDRA-12888 is resolved, a tiny stream (e.g. < 100kb) could be sent 
> through the write path to be buffered by memtables instead of creating an 
> SSTable each.
> Without CASSANDRA-12888 this would break incremental repairs.
