From 375394dc9901ec55b6d5a2d00584bbae6263457a Mon Sep 17 00:00:00 2001 From: Pavel Karpy Date: Mon, 27 Dec 2021 21:07:02 +0300 Subject: [PATCH] [#1059] shard: Add shard mode to shard `Info` Provide shard mode information via `DumpInfo()`. Delete atomic field from Shard structure since it duplicates new field.
