Although I was not listed as a reviewer, I took a look and it appears to be an improvement. Thank you for working on this @aashishkohli !

Should be replace by:

SELECT *
FROM clusterAllReplicas('default', view(
    SELECT
        hostname() AS server,
        getSetting('max_threads') as cpu_cores,
         formatReadableSize(getSetting('max_memory_usage')) as memory
    FROM system.one
))
ORDER BY server ASC
SETTINGS skip_unavailable_shards = 1
