• optional google.protobuf.UInt32Value window_bits = 1

  Value from 9 to 15 that represents the base two logarithmic of the decompressor's window size. The decompression window size needs to be equal or larger than the compression window size. The default window size is 15. This is so that the decompressor can decompress a response compressed by a compressor with any compression window size. For more details about this parameter, please refer to `zlib manual <https://www.zlib.net/manual.html>`_ > inflateInit2.

• optional google.protobuf.UInt32Value chunk_size = 2

  Value for zlib's decompressor output buffer. If not set, defaults to 4096. See https://www.zlib.net/manual.html for more details.

• optional google.protobuf.UInt32Value max_inflate_ratio = 3

  An upper bound to the number of times the output buffer is allowed to be bigger than the size of the accumulated input. This value is used to prevent decompression bombs. If not set, defaults to 100. [#comment:TODO(rojkov): Re-design the Decompressor interface to handle compression bombs gracefully instead of this quick solution. See https://github.com/envoyproxy/envoy/commit/d4c39e635603e2f23e1e08ddecf5a5fb5a706338 for details.]
