Which Delta project/connector is this regarding?
Description
DeltaTableV2.snapshotcan be stale, if the object was instantiated long before the command using it. This can happen, for example, with aDeltaTable(which binds an internalDeltaTableV2when constructed and never refreshes it). This can be dangerous, so we rename the field and document the danger so it is less likely to cause bugs.How was this patch tested?
Field rename - compilation suffices.
