Enum DocumentSumMode 

Source 
pub enum DocumentSumMode {
    Total,
    PerInValue,
    RangeNoProof,
    RangeProof,
    RangeDistinctProof,
    PointLookupProof,
    RangeAggregateCarrierProof,
}
Expand description

The lower-level routing decision the dispatcher reaches after detecting the query’s shape. Parallels count’s DocumentCountMode.

Where SumMode is what the caller asked for (an externally-facing classification), DocumentSumMode is which executor will run (an internally-facing classification that maps onto a specific grovedb primitive). The dispatcher’s job is to translate from the former to the latter.

Variants§

§

Total

Aggregate + no where → primary-key SumTree fast path.

§

PerInValue

Aggregate or GroupByIn + Equal/In where clauses fully covering a summable: "<prop>" index.

§

RangeNoProof

Aggregate + range where → AggregateSumOnRange no-prove path (or its proven counterpart on the prove path).

§

RangeProof

Aggregate + range where + prove = true → grovedb AggregateSumOnRange proof primitive.

§

RangeDistinctProof

GroupByRange (or GroupByCompound distinct mode) → per-key KVSum walk with proof.

§

PointLookupProof

Point-lookup with proof.

§

RangeAggregateCarrierProof

Carrier-aggregate: outer In/range with inner range, sum committed per outer bucket. Sum analog of count’s RangeAggregateCarrierProof.
