-# compress

-

-This package provides various compression algorithms.

-

-* [zstandard](https://github.com/klauspost/compress/tree/master/zstd#zstd) compression and decompression in pure Go.

-* [S2](https://github.com/klauspost/compress/tree/master/s2#s2-compression) is a high performance replacement for Snappy.

-* Optimized [deflate](https://godoc.org/github.com/klauspost/compress/flate) packages which can be used as a dropin replacement for [gzip](https://godoc.org/github.com/klauspost/compress/gzip), [zip](https://godoc.org/github.com/klauspost/compress/zip) and [zlib](https://godoc.org/github.com/klauspost/compress/zlib).

-* [snappy](https://github.com/klauspost/compress/tree/master/snappy) is a drop-in replacement for `github.com/golang/snappy` offering better compression and concurrent streams.

-* [huff0](https://github.com/klauspost/compress/tree/master/huff0) and [FSE](https://github.com/klauspost/compress/tree/master/fse) implementations for raw entropy encoding.

-* [gzhttp](https://github.com/klauspost/compress/tree/master/gzhttp) Provides client and server wrappers for handling gzipped/zstd HTTP requests efficiently.

-* [pgzip](https://github.com/klauspost/pgzip) is a separate package that provides a very fast parallel gzip implementation.

-# package usage

-

-Use `go get github.com/klauspost/compress@latest` to add it to your project.

-

-This package will support the current Go version and 2 versions back.

-

-* Use the `nounsafe` tag to disable all use of the "unsafe" package.

-* Use the `noasm` tag to disable all assembly across packages.

-

-Use the links above for more information on each.

-	* gzhttp: Make content-type optional [#510](https://github.com/klauspost/compress/pull/510)

-

-Both compression and decompression now supports "synchronous" stream operations. This means that whenever "concurrency" is set to 1, they will operate without spawning goroutines.

-

-Stream decompression is now faster on asynchronous, since the goroutine allocation much more effectively splits the workload. On typical streams this will typically use 2 cores fully for decompression. When a stream has finished decoding no goroutines will be left over, so decoders can now safely be pooled and still be garbage collected.

-

-While the release has been extensively tested, it is recommended to testing when upgrading.

-# deflate usage

-

-The packages are drop-in replacements for standard library [deflate](https://godoc.org/github.com/klauspost/compress/flate), [gzip](https://godoc.org/github.com/klauspost/compress/gzip), [zip](https://godoc.org/github.com/klauspost/compress/zip), and [zlib](https://godoc.org/github.com/klauspost/compress/zlib). Simply replace the import path to use them:

-

-Typical speed is about 2x of the standard library packages.

-You may also be interested in [pgzip](https://github.com/klauspost/pgzip), which is a drop-in replacement for gzip, which support multithreaded compression on big files and the optimized [crc32](https://github.com/klauspost/crc32) package used by these packages.

-

-The packages implement the same API as the standard library, so you can use the original godoc documentation: [gzip](http://golang.org/pkg/compress/gzip/), [zip](http://golang.org/pkg/archive/zip/), [zlib](http://golang.org/pkg/compress/zlib/), [flate](http://golang.org/pkg/compress/flate/).

-

-Currently there is only minor speedup on decompression (mostly CRC32 calculation).

-

-Memory usage is typically 1MB for a Writer. stdlib is in the same range. 

-If you expect to have a lot of concurrently allocated Writers consider using 

-the stateless compression described below.

-

-For compression performance, see: [this spreadsheet](https://docs.google.com/spreadsheets/d/1nuNE2nPfuINCZJRMt6wFWhKpToF95I47XjSsc-1rbPQ/edit?usp=sharing).

-

-To disable all assembly add `-tags=noasm`. This works across all packages.

-

-# Stateless compression

-

-This package offers stateless compression as a special option for gzip/deflate. 

-It will do compression but without maintaining any state between Write calls.

-

-This means there will be no memory kept between Write calls, but compression and speed will be suboptimal.

-

-This is only relevant in cases where you expect to run many thousands of compressors concurrently, 

-but with very little activity. This is *not* intended for regular web servers serving individual requests.  

-

-Because of this, the size of actual Write calls will affect output size.

-

-In gzip, specify level `-3` / `gzip.StatelessCompression` to enable.

-

-For direct deflate use, NewStatelessWriter and StatelessDeflate are available. See [documentation](https://godoc.org/github.com/klauspost/compress/flate#NewStatelessWriter)

-

-A `bufio.Writer` can of course be used to control write sizes. For example, to use a 4KB buffer:

-

-```go

-	// replace 'ioutil.Discard' with your output.

-	gzw, err := gzip.NewWriterLevel(ioutil.Discard, gzip.StatelessCompression)

-	if err != nil {

-		return err

-	}

-	defer gzw.Close()

-

-	w := bufio.NewWriterSize(gzw, 4096)

-	defer w.Flush()

-	

-	// Write to 'w' 

-```

-

-This will only use up to 4KB in memory when the writer is idle. 

-

-Compression is almost always worse than the fastest compression level 

-and each write will allocate (a little) memory.
