public class VeniceResponseDecompressor
extends Object

This class is used to handle all the decompression related logic in Router, and it will be used in VeniceResponseAggregator for regular requests and VeniceDispatcher for streaming requests.

Constructor Details

VeniceResponseDecompressor

public VeniceResponseDecompressor(CompressionStrategy clientCompression,
 RouterStats<AggRouterHttpRequestStats> routerStats,
 StoreVersionName storeVersionName,
 CompressorFactory compressorFactory)

Method Details

getCompressionStrategy

public static CompressionStrategy getCompressionStrategy(String compressionHeader)

canPassThroughResponse

public boolean canPassThroughResponse(CompressionStrategy responseCompression)

decompressSingleGetContent

public ContentDecompressResult decompressSingleGetContent(CompressionStrategy compressionStrategy,
 io.netty.buffer.ByteBuf content)

decompressMultiGetContent

public ContentDecompressResult decompressMultiGetContent(CompressionStrategy compressionStrategy,
 io.netty.buffer.ByteBuf content)

Decompressing multi-get response in router side is a bit of overhead. Since records could be concatenated within one response, we need to deserialize the records; decompress the records and then serialize them back.

processMultiGetResponseForStreaming

public Pair<io.netty.buffer.ByteBuf,CompressionStrategy> processMultiGetResponseForStreaming(CompressionStrategy responseCompression,
 io.netty.buffer.ByteBuf content)
