### 4. Excluded Types

- Already compressed objects are not fit for compression since they do not have compressible patterns.
Such objects do not produce efficient [`LZ compression`](https://en.wikipedia.org/wiki/LZ77_and_LZ78)
which is a fitness factor for a lossless data compression.

Pre-compressed input typically compresses in excess of 2GiB/s per core,

      decompress(response)
    } else {
      chain.proceed(chain.request())
    }

  /**
   * Returns a decompressed copy of the Response, typically via a streaming Source.
   * If no known decompression or the response is not compressed, returns the response unmodified.
   */
  internal fun decompress(response: Response): Response {
    if (!response.promisesBody()) {
      return response

        header("Content-Encoding", "gzip")
      }

    val decompressed = zstdInterceptor.decompress(response)
    assertThat(decompressed.header("Content-Encoding")).isNull()

    val responseString = decompressed.body.string()
    assertThat(responseString).isEqualTo("hello gzip world")
  }

  @Test
  fun testNoDecompress() {
    val s = "hello not compressed world".encodeUtf8()

Interceptors can be chained. Suppose you have both a compressing interceptor and a checksumming interceptor: you'll need to decide whether data is compressed and then checksummed, or checksummed and then compressed. OkHttp uses lists to track interceptors, and interceptors are called in order.

### Application Interceptors

If there's no `gzip` in the header, it will not try to decompress the body.

That way, the same route class can handle gzip compressed or uncompressed requests.

### Create a custom `GzipRoute` class { #create-a-custom-gziproute-class }

      disable: true # optionally turn-off snowball archive transfer
#      batch: 100 # upto this many objects per archive
#      inmemory: true # indicates if the archive must be staged locally or in-memory
#      compress: false # S2/Snappy compressed archive
#      smallerThan: 5MiB # create archive for all objects smaller than 5MiB
#      skipErrs: false # skips any source side read() errors

  # target where the objects must be replicated
  target:

- Objects must be in CSV, JSON, or Parquet(*) format.
- UTF-8 is the only encoding type the Select API supports.
- GZIP or BZIP2 - CSV and JSON files can be compressed using GZIP, BZIP2, [ZSTD](https://facebook.github.io/zstd/), and streaming formats of [LZ4](https://lz4.github.io/lz4/), [S2](https://github.com/klauspost/compress/tree/master/s2#s2-compression) and [SNAPPY](http://google.github.io/snappy/).
