Description

Currently

Conditions.notExists(key)

will both return true if there were no such key or if it was removed. New condition that will allow to detect whether a key was removed or not created is required. It might look like

Conditions.isTombstone(key)

or similar.

 

Seems that it'll be also helpful if org.apache.ignite.internal.metastorage.client.Conditions#notExists

javadoc' will be more specific about tombstone case.
