Enum MergeMode 

pub enum MergeMode {
    Unordered,
    Ordered,
    Sorted,
}

How a merge combines its inputs.

Reference: https://ytsaurus.tech/docs/en/user-guide/data-processing/operations/merge

Variants

Unordered

Rows in no particular order. The cluster’s own default, and the cheapest.

Ordered

Rows in the order of the input tables, each table’s order preserved.

Sorted

A sorted merge of sorted inputs, producing a sorted table.

The inputs must already be sorted. merge_by is optional — measured against a cluster, a sorted merge without it takes the key from the inputs’ own sort columns — and MergeSpec::with_merge_by is for merging by fewer columns than that, or for saying so out loud.

Implementations
