## `GZipMiddleware` { #gzipmiddleware }

Gerencia respostas GZip para qualquer requisição que inclua `"gzip"` no cabeçalho `Accept-Encoding`.

O middleware lidará com respostas padrão e de streaming.

Os seguintes argumentos são suportados:

* `minimum_size` - Não comprima respostas menores que este tamanho mínimo em bytes. O padrão é `500`.

arrive, the stream is closed, or a timeout elapses. If we get bytes but there's nobody asking for them, we buffer them. We don't consider bytes as delivered for flow control until they're consumed by the application.

Consider an application streaming a video over http/2. Perhaps the user pauses the video and the application stops reading bytes from this stream. The buffer will fill up, and flow control prevents the server from sending more data on this stream. When the user unpauses her video...

- 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/).
