WarehouseTableInfo
data class WarehouseTableInfo(val name: String, val uuid: String, val tableEngine: String, val modifiedAt: String, val columns: String = "")
A table or view of the warehouse as its list says: its name, uuid, tableEngine (the kind of table, as the warehouse names it), when its metadata last changed (modifiedAt) and a fingerprint of its columns (columns: their positions, names and types), both opaque text compared for change only. The fingerprint tells a change the time cannot, such as an ALTER in the same second as the last look.
