    enhance: [2.6] Cherry pick nil type row based feature & bump version (#48464)

    frostbyte_neo 发布于 2026-03-24 06:19:30 +00:00

    Cherry-pick from master
    pr: #47712
    Related to #47711

    Enable Go pointer struct fields (*string, *int32, etc.) to represent
    nullable columns in the row-based data processing path. A nil pointer
    maps to a NULL value in Milvus; a non-nil pointer dereferences to the
    actual value.

    Changes:

    • ParseSchema: pointer fields auto-infer Nullable=true (PK excluded)
    • AnyToColumns: use reflect.Value.IsNil() to call AppendNull for nil
      pointers, Elem().Interface() for non-nil — bypasses Go's typed-nil
      problem where (*T)(nil) as interface{} is != nil
    • SetField: wrap/unwrap pointer values during field assignment
    • fillData/fillPKEntry: check IsNull() on columns and set nil pointers
      for null values, wrap non-null values in reflect.New pointers
    • Dynamic field path: same nil/deref logic for pointer fields going into
      the JSON dynamic column
