> Nothing fancy on this table (there is only one active table on this cluster): STCS with defaults, no MVs, no indexes just text and int columns with a single value partition key.
> NOTE: once restarted, the values then display as correct, creeping up from there (thus my thinking that this is a compaction issue).
