I've created the kvstore with following configuration:
_key, targetUser, action, time
(the action will be add or remove)
If the following entry exists: bob, add, 1552602818
And I will add to kvstore the entry "bob, remove, 1552603818", action and time fields should be updated, rather than creating new entry
If targetUser is different (not existing in the kvstore) entry should be added.
Is this possible? I will need to populate the kvstore as events arrive using a scheduled search.
