Types

type Qatzstd

type Qatzstd struct {

	// Set compression parameters according to pre-defined compression level table.
	// Note that exact compression parameters are dynamically determined,
	// depending on both compression level and source content size (when known).
	// Value 0 means default, and default level is 3.
	//
	// Setting a level does not automatically set all other compression parameters
	// to default. Setting this will however eventually dynamically impact the compression
	// parameters which have not been manually set. The manually set
	// ones will 'stick'.
	CompressionLevel *wrapperspb.UInt32Value `protobuf:"bytes,1,opt,name=compression_level,json=compressionLevel,proto3" json:"compression_level,omitempty"`
	// A 32-bits checksum of content is written at end of frame. If not set, defaults to false.
	EnableChecksum bool `protobuf:"varint,2,opt,name=enable_checksum,json=enableChecksum,proto3" json:"enable_checksum,omitempty"`
	// The higher the value of selected strategy, the more complex it is,
	// resulting in stronger and slower compression.
	//
	// Special: value 0 means "use default strategy".
	Strategy Qatzstd_Strategy `` /* 148-byte string literal not displayed */
	// Value for compressor's next output buffer. If not set, defaults to 4096.
	ChunkSize *wrapperspb.UInt32Value `protobuf:"bytes,5,opt,name=chunk_size,json=chunkSize,proto3" json:"chunk_size,omitempty"`
	// Enable QAT to accelerate Zstd compression or not. If not set, defaults to false.
	//
	// This is useful in the case that users want to enable QAT for a period of time and disable QAT for another period of time,
	// they don't have to change the config too much or prepare for another config that has software zstd compressor and just changing the value of this filed.
	EnableQatZstd bool `protobuf:"varint,6,opt,name=enable_qat_zstd,json=enableQatZstd,proto3" json:"enable_qat_zstd,omitempty"`
	// Fallback to software for Qatzstd when input size is less than this value.
	// Valid only “enable_qat_zstd“ is “true“. 0 means no fallback at all. If not set, defaults to 4000.
	QatZstdFallbackThreshold *wrapperspb.UInt32Value `` /* 137-byte string literal not displayed */
	// contains filtered or unexported fields
}
