> We do not save an upsampled index summaries
> -------------------------------------------
>
> Key: CASSANDRA-10512
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10512
> Project: Cassandra
> Issue Type: Bug
> Components: Local Write-Read Paths
> Reporter: Benedict
> Assignee: Ariel Weisberg
> Fix For: 3.0.x
>
>
> If we downsample an index summary, we overwrite the existing summary, despite
> downsampling being inexpensive. However on upsampling (which is expensive) we
> do not, so that on restart all of our index summaries are the smallest they
> have ever been adjusted to.
