Hi there, Today I come up with the following thesis:
A rebuild / removenode may break the base-table <> MV contract. I'd even claim that a rebuild / removenode requires rebuilding all MVs to guarantee MV consistency. Reason: A node can have base tables with MVs. This is no problem. If these are streamed during rebuild/removenode, underlying MVs are updated by write path and consistency contract will be fulfilled. BUT a node may also contain ranges for MVs whose base table reside on a different node. When these are streamed from a another node, then for example base table on node A suddenly has the replica from the base table of node B and this is not consistent any more.
