I've merged them. ``` Title: uuid comparison rules Currently comparison between uuid values is supported. Example: ```lua u1 = uuid.fromstr('aaaaaaaa-aaaa-4000-b000-000000000001') u2 = uuid.fromstr('bbbbbbbb-bbbb-4000-b000-000000000001') u1 > u2 -- false u1 >= u2 -- false u1 <= u2 -- true u1 < u2 -- true ``` Also it's possible to compare uuid values with its string representations: ```lua u1_str = 'aaaaaaaa-aaaa-4000-b000-000000000001' u1 = uuid.fromstr(u1_str) u2_str = 'bbbbbbbb-bbbb-4000-b000-000000000001' u1 == u1_str -- true u1 == u2_str -- false u1 >= u1_str -- true u1 < u2_str -- true ``` ``` >> --- >> Issue:https://github.com/tarantool/tarantool/issues/5511 >> Branch:https://github.com/tarantool/tarantool/tree/olegrok/5511-uuid-cmp-v2 >> >> diff --git a/test/app/uuid.result b/test/app/uuid.result >> index e06331001..5b9ffa230 100644 >> --- a/test/app/uuid.result >> +++ b/test/app/uuid.result > 2.

Yes, it was added before https://github.com/tarantool/tarantool/blob/e23b14dc23d749d092295a9b84854e1d64b2db27/test/app/uuid.test.lua#L89
