FetchLog

The FetchLog operator fetches logs from the log service

Filter

The Filter operator filters the collection with specified criteria

GetResult

Knn

The Knn operator searches for the nearest neighbours of the specified embedding. This is intended to use by executor

KnnBatch

The KnnBatch operator searches for the nearest neighbours of the specified embedding. This is intended to use by frontend

KnnBatchResult

KnnOutput

KnnProjection

The KnnProjection operator retrieves record content by offset ids It is based on ProjectionOperator, and it attaches the distance of the records to the target embedding to the record content

KnnProjectionOutput

KnnProjectionRecord

KnnQuery

Limit

The Limit operator selects a range or records sorted by their offset ids

Merge

The Merge operator selects the top records from the batch vectors of records which are all sorted in descending order. If the same record occurs multiple times only one copy will remain in the final result.

Projection

The Projection operator retrieves record content by offset ids

ProjectionOutput

ProjectionRecord

Rank

RecordMeasure

The RecordDistance represents a measure of embedding (identified by offset_id) with respect to query embedding
