ColumnFloatVectorArray

A ColumnFloatVectorArray instance represents an ArrayOfVector float-vector column whose rows contain float-vector values with a shared dimension. Nullable semantics are enforced in v3.0.0: nullability flags and valid-value bookkeeping are real operations instead of stubs.

go
type ColumnFloatVectorArray struct {
}

BUILDER METHODS:

AppendValue(value any) error

This appends one row supplied as []entity.FloatVector or [][]float32.
IsNull(idx int) (bool, error)

This reports whether the row at the given index is null.
Nullable() bool

This reports whether the column accepts null values.
SetNullable(nullable bool)

This sets whether the column accepts null values.
ValidCount() int

This returns the number of non-null rows.
ValidateNullable() error

This verifies the internal nullable bookkeeping and returns an error on mismatch.

METHODS:

Slice(start, end int) Column

Example

Demonstrates ColumnFloatVectorArray usage.

go
import (
	"fmt"

	"github.com/milvus-io/milvus/client/v3/column"
)

values := column.NewColumnFloatVectorArray("embeddings", 4, [][][]float32{{{0.1, 0.2, 0.3, 0.4}}})
fmt.Println(values.Len())
