From 977a20760b8593be7e05a539e357423eb7c3bdcf Mon Sep 17 00:00:00 2001 From: Denis Kirillov Date: Wed, 17 Jul 2024 17:40:23 +0300 Subject: [PATCH] [#430] Delete all split version at once Previously after split we can get two `null` versioned object with the same key and deleting such key removes only one node/object.
