> OAK-4112 introduced {{CacheChangesTracker}} mechanism, inspired by the {{QueryContext}} class, already present in the RDB DS.
> The tracker works on the {{NodeDocumentCache}} level, within the methods modifying the cache values, using the same {{NodeDocumentLocks}}, which may prevent potential concurrency problems, described in the comments to OAK-3566.
> We should synchronise both approaches, so the queries in Mongo and RDB uses the same logic to update their caches.
