Description

Creates a flow that gzip-compresses a stream of ByteStrings. Note that the compressor will SYNC_FLUSH after every ByteStringByteString so that it is guaranteed that every ByteStringByteString coming out of the flow can be fully decompressed without waiting for additional data. This may come at a compression performance cost for very small chunks.

Use the overload method to control the compression level.

Since 1.3.0, an overload with an autoFlush parameter is also available. If autoFlush is true (the default for the other overloads), the compressor flushes after every single element in the stream. If it is false, the compressor only emits output when the compression algorithm produces it, which can improve the compression ratio for small chunks, but an emitted ByteString may not be fully decompressible until more data arrives.
