Types

type AggBytesGetter 

type AggBytesGetter func() []byte

the definition of functions to get and set the aggregation result.

type AggBytesSetter 

type AggBytesSetter func(value []byte) error

the definition of functions to get and set the aggregation result.

type AggCanMarshal 

type AggCanMarshal interface {
	Marshal() []byte
	Unmarshal([]byte)
}

AggCanMarshal interface is used for agg structures' multi-node communication. each context of aggregation should implement the AggCanMarshal interface.

todo: consider that change them to deliver []byte directly, and agg developer choose how to use the []byte. 

because the []byte can be set to one byte vector, and we can use the `mpool` to manage the memory easily.

type AggCommonContextInit added in v1.2.1 

type AggCommonContextInit func(resultType types.Type, parameters ...types.Type) AggCommonExecContext

type AggCommonExecContext 

type AggCommonExecContext interface {
	AggCanMarshal
}

AggCommonExecContext stores the common context for all the groups. like the type scale, timezone and so on.

type AggContext added in v1.2.1 

type AggContext struct {
	// contains filtered or unexported fields
}

type AggFuncExec 

type AggFuncExec interface {
	AggID() int64
	IsDistinct() bool

	// TypesInfo return the argument types and return type of the function.
	TypesInfo() ([]types.Type, types.Type)

	// GroupGrow is used to increase the aggregation's group size.
	GroupGrow(more int) error
	// PreAllocateGroups is used to pre-extend the agg memory to reduce gc cost.
	PreAllocateGroups(more int) error

	// Fill BulkFill and BatchFill add the value to the aggregation.
	Fill(groupIndex int, row int, vectors []*vector.Vector) error
	BulkFill(groupIndex int, vectors []*vector.Vector) error
	BatchFill(offset int, groups []uint64, vectors []*vector.Vector) error

	// Merge merges the aggregation result of two groups.
	Merge(next AggFuncExec, groupIdx1, groupIdx2 int) error
	// BatchMerge merges the aggregation result of multiple groups.
	// merge work starts from the offset group of the next agg, end at the (offset + len(groups) - 1) group.
	// merges the (offset + i)th group with the (groups[i]-1) group of the current agg.
	BatchMerge(next AggFuncExec, offset int, groups []uint64) error

	// SetExtraInformation add an additional information to agg executor.
	// in most cases, it is used to set the partial result of the aggregation to speed up.
	//
	// but for the 'group_concat', it was a bad hack to use the method to set the separator.
	// and for the 'cluster_centers', it was used to set the fields of this agg.
	// todo: the old implementation is not good, we should use the vector.Vector to replace the any.
	//  and the hacks should be removed.
	//  but for first version, I will keep it.
	SetExtraInformation(partialResult any, groupIndex int) (err error)

	// Flush return the aggregation result.
	Flush() (*vector.Vector, error)

	// Free clean the resource and reuse the aggregation if possible.
	Free()
	// contains filtered or unexported methods
}

AggFuncExec is an interface to do execution for aggregation.
