-- Here we use a trick with shardNum() to generate unique data on each shard.
-- Since distributed_group_by_no_merge=2 will use WithMergeableStateAfterAggregationAndLimit,
-- which assume that the data on shards is unique
-- (LIMIT BY will be applied only on shards, not on the initiator).
-- To distinguish echoing from the comments above we use SELECT FORMAT Null.
