These performance points occur due to the behaviour of tombstones throughout reads. In a spread query, your Cassandra driver will usually use paging, which allows nodes to return a limited variety of nagrobki responses at a time. When cassandra tombstones are concerned, the node must hold the tombstones that it has encountered in memory and return them to the coordinator, in case one of the other replicas is unaware that the related data has been deleted.
Tombstones are writes – they go through the traditional write path, take up area on disk, and make use of Cassandra’s consistency mechanisms. If a cluster is managed properly, this ensures that information will remain deleted even when a node is down when the delete is issued. Our range includes numerous different sizes, and types of gra...
