In this configuration, table 3 is FLCS. It looks like format just sets up tiered storage on the connection, so all of the tables – including this FLCS – are tiered. We've made little effort (so far) to make sure non-row-store tables work on tiered storage. But I figured I should flag this in case it turns out to be symptom of something more significant.
