Types

type Fuser 

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

Fuser buffers records written to it, assembling from them a unified schema of fields and types. Fuser then transforms those records to the unified schema as they are read back from it.

func NewFuser 

func NewFuser(zctx *zed.Context, memMaxBytes int) *Fuser

NewFuser returns a new Fuser. The Fuser buffers records in memory until their cumulative size (measured in zcode.Bytes length) exceeds memMaxBytes, at which point it buffers them in a temporary file.

func (*Fuser) Close 

func (f *Fuser) Close() error

Close removes the receiver's temporary file if it created one.

func (*Fuser) Read 

func (f *Fuser) Read() (*zed.Value, error)

Read returns the next buffered record after transforming it to the unified schema.

func (*Fuser) Write 

func (f *Fuser) Write(rec *zed.Value) error

Write buffers rec. If called after Read, Write panics.

type Proc 

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

func New 

func New(pctx *proc.Context, parent proc.Interface) (*Proc, error)

func (*Proc) Done 

func (p *Proc) Done()

func (*Proc) Pull 

func (p *Proc) Pull() (zbuf.Batch, error)
