> Project: Phoenix
> Issue Type: Bug

> I just loaded a table with a few million rows. After the load I flushed and
> major compacted the table.
> In the stats table I see that GUIDE_POSTS_ROW_COUNT was exactly 10485760 for
> each guide post (that's exactly 1024 * 1024 * 10), which is strange... and
> not correct - the table has 16m rows, but the guide posts added up to over
> 30m rows. Running UPDATE STATISTICS fixed it to about 3.5m rows per guide
> post, it should not be by a factor of 3 off from a major compaction.
> Not sure about the cause, but wanted to report to that I (or someone) can
> keep track of it.
> This was with a build from the 4.7.0-0.98 tag.
