Types ¶

type Batch ¶

type Batch struct {
	// For recursive CTE, 1 is last batch, 2 is end of batch
	Recursive int32
	// Ro if true, Attrs is read only
	Ro         bool
	ShuffleIDX int //used only in shuffle dispatch
	// reference count, default is 1
	Cnt int64
	// Attrs column name list
	Attrs []string
	// Vecs col data
	Vecs []*vector.Vector
	// ring
	Aggs []agg.Agg[any]

	AuxData any // hash table, runtime filter, etc.
	// contains filtered or unexported fields
}

Batch represents a part of a relationship including an optional list of row numbers, columns and list of attributes

(SelsData, Sels) - list of row numbers
(Attrs) - list of attributes
(vecs) 	- columns
