Please, take a look at the PR to IGNITE-10377. Seems it is already fixed, but may be in non-ideal way.
I'd think we can cleanup txLog structure or region if all mvcc caches was destroyed on node.

> Actually TxLog creates on each data node regardless the node is affinity node for any MVCC cache or not. There is no sense to create and maintain Tx log and Vacuum routines in case the node doesn't have any mvcc cache.
