---------------------------------------
|
|
||||||
The snappy-java is a Java port of the snappy http://code.google.com/p/snappy/, a fast compresser/decompresser written in C++ developed by Google.
|
|
||||||
|
|
||||||
== Features ==
|
|
||||||
* [http://www.apache.org/licenses/LICENSE-2.0 Apache Licence Version 2.0]. Free for both commercial and non-commercial use.
|
|
||||||
* Fast compression/decompression tailored to 64-bit CPU architecture.
|
|
||||||
* JNI-based implementation to achieve comparable performance to the native C++ version.
|
|
||||||
* Although snappy-java uses JNI, it can be used safely with multiple class loaders (e.g. Tomcat, etc.).
|
|
||||||
* Portable across various operating systems; Snappy-java contains native libraries built for Window/Mac/Linux (32/64-bit). At runtime, snappy-java loads one of these libraries according to your machine environment (It looks system properties, `os.name` and `os.arch`).
|
|
||||||
* Simple usage. Add the snappy-java-(version).jar file to your classpath. Then call compression/decompression methods in org.xerial.snappy.Snappy.
|
|
||||||
|
|
||||||
== Performance ==
|
|
||||||
* Snappy's main target is very high-speed compression/decompression with reasonable compression size. So the compression ratio of snappy-java is modest and about the same as `LZF` (ranging 20%-100% according to the dataset).
|
|
||||||
|
|
||||||
* Here are some [https://github.com/ning/jvm-compressor-benchmark/wiki benchmark results], comparing snappy-java and the other compressors `LZO-java`/`LZF`/`QuickLZ`/`Gzip`/`Bzip2`. Thanks [http://twitter.com/#!/cowtowncoder Tatu Saloranta @cowtowncoder] for providing the benchmark suite.
|
|
||||||
* The benchmark result indicates snappy-java is the fastest compreesor/decompressor in Java:
|
|
||||||
* http://ning.github.com/jvm-compressor-benchmark/results/canterbury-roundtrip-2011-07-28/index.html
|
|
||||||
* The decompression speed is twice as fast as the others:
|
|
||||||
* http://ning.github.com/jvm-compressor-benchmark/results/canterbury-uncompress-2011-07-28/index.html
|

|
|
||||||
* [Milestone] release plans
|

|
||||||
If you are a Maven user, see [#Using_with_Maven]
|
|
||||||
|
|
||||||
== Usage ==
|
|
||||||
First, import `org.xerial.snapy.Snappy` in your Java code:
|
|
||||||
{{{
|
|
||||||
import org.xerial.snappy.Snappy;
|
|
||||||
}}}
|
|
||||||
|
|
||||||
Then use `Snappy.compress(byte[])` and `Snappy.uncompress(byte[])`:
|
|
||||||
{{{
|
|
||||||
String input = "Hello snappy-java! Snappy-java is a JNI-based wrapper of "
|
|
||||||
+ "Snappy, a fast compresser/decompresser.";
|
|
||||||
byte[] compressed = Snappy.compress(input.getBytes("UTF-8"));
|
|
||||||
byte[] uncompressed = Snappy.uncompress(compressed);
|
|
||||||
|
|
||||||
String result = new String(uncompressed, "UTF-8");
|
|
||||||
System.out.println(result);
|
|
||||||
}}}
|
|
||||||
|
|
||||||
In addition, high-level methods (`Snappy.compress(String)`, `Snappy.compress(float[] ..)` etc. ) and low-level ones (e.g. `Snappy.rawCompress(.. )`, `Snappy.rawUncompress(..)`, etc.), which minimize memory copies, can be used. See also
|
|
||||||
[http://code.google.com/p/snappy-java/source/browse/src/main/java/org/xerial/snappy/Snappy.java Snappy.java]
|
|
||||||
|
|
||||||
===Stream-based API===
|
|
||||||
Stream-based compressor/decompressor `SnappyOutputStream`/`SnappyInputStream` are also available for reading/writing large data sets.
|
|
||||||
|
|
||||||
===Setting classpath==
|
|
||||||
If you have snappy-java-(VERSION).jar in the current directory, use `-classpath` option as follows:
|
|
||||||
{{{
|
|
||||||
$ javac -classpath ".;snappy-java-(VERSION).jar" Sample.java # in Windows
|
|
||||||
or
|
|
||||||
$ javac -classpath ".:snappy-java-(VERSION).jar" Sample.java # in Mac or Linux
|
|
||||||
}}}
|
|
||||||
|
|
||||||
===Using with Maven===
|
|
||||||
* Snappy-java is available from Maven's central repository: http://repo1.maven.org/maven2/org/xerial/snappy/snappy-java
|
|
||||||
|
|
||||||
Add the following dependency to your pom.xml:
|
|
||||||
{{{
|
|
||||||
<dependency>
|
|
||||||
<groupId>org.xerial.snappy</groupId>
|
|
||||||
<artifactId>snappy-java</artifactId>
|
|
||||||
<version>(version)</version>
|
|
||||||
<type>jar</type>
|
|
||||||
<scope>compile</scope>
|
|
||||||
</dependency>
|
|
||||||
}}}
|
|
||||||
|
|
||||||
==Public discussion group==
|
|
||||||
Post bug reports or feature request to the Issue Tracker: http://code.google.com/p/snappy-java/issues/list
|
|
||||||
|
|
||||||
Public discussion forum is here: [http://groups.google.com/group/xerial?hl=en Xerial Public Discussion Group].
|
|
||||||
|
|
||||||
|
|
||||||
== Building from the source code ==
|
|
||||||
See the [http://code.google.com/p/snappy-java/source/browse/INSTALL installation instruction]. Building from the source code is an option when your OS platform and CPU architecture is not supported. To build snappy-java, you need Mercurial(hg), JDK (1.6 or higher), Maven (3.x or higher is required), g++ compiler (mingw in Windows) etc.
|
|
||||||
|
|
||||||
{{{
|
|
||||||
$ hg clone https://snappy-java.googlecode.com/hg/ snappy-java
|
|
||||||
$ cd snappy-java
|
|
||||||
$ make
|
|
||||||
}}}
|
|
||||||
|
|
||||||
A file `target/snappy-java-$(version).jar` is the product additionally containing the native library built for your platform.
|
|
||||||
|
|
||||||
==Miscellaneous Notes==
|
|
||||||
===Using snappy-java with Tomcat 6 (or higher) Web Server===
|
|
||||||
|
|
||||||
Simply put the snappy-java's jar to WEB-INF/lib folder of your web application. Usual JNI-library specific problem no longer exists since snappy-java version 1.0.3 or higher can be loaded by multiple class loaders in the same JVM by using native code injection to the parent class loader (Issue 21).

## Usage
|
||||||
|
First, import `org.xerial.snapy.Snappy` in your Java code:
|
||||||
|
|
||||||
|
import org.xerial.snappy.Snappy;
|
||||||
|
|
||||||
|
|
||||||
|
Then use `Snappy.compress(byte[])` and `Snappy.uncompress(byte[])`:
|
||||||
|
|
||||||
|
String input = "Hello snappy-java! Snappy-java is a JNI-based wrapper of "
|
||||||
|
+ "Snappy, a fast compresser/decompresser.";
|
||||||
|
byte[] compressed = Snappy.compress(input.getBytes("UTF-8"));
|
||||||
|
byte[] uncompressed = Snappy.uncompress(compressed);
|
||||||
|
|
||||||
|
String result = new String(uncompressed, "UTF-8");
|
||||||
|
System.out.println(result);
|
||||||
|
|
||||||
|
|
||||||
|
In addition, high-level methods (`Snappy.compress(String)`, `Snappy.compress(float[] ..)` etc. ) and low-level ones (e.g. `Snappy.rawCompress(.. )`, `Snappy.rawUncompress(..)`, etc.), which minimize memory copies, can be used. See also

$ git clone https://github.com/xerial/snappy-java.git
|
||||||
|
$ cd snappy-java
|
||||||
|
$ make
|
||||||
|
|
||||||
|
|
||||||
|
A file `target/snappy-java-$(version).jar` is the product additionally containing the native library built for your platform.
|
||||||
|
|
||||||
|
## Cross-compiling for other platforms
|
||||||
|
The Makefile contains rules for cross-compiling the native library for other platforms so that the snappy-java JAR can support multiple platforms. For example, to build the native libraries for x86 Linux, x86 and x86-64 Windows, and soft- and hard-float ARM:
|
||||||
|
|
||||||
|
$ make linux32 win32 win64 linux-arm linux-armhf
|
||||||
|
|
||||||
|
If you append `snappy` to the line above, it will also build the native library for the current platform and then build the snappy-java JAR (containing all native libraries built so far).
|
||||||
|
|
||||||
|
Of course, you must first have the necessary cross-compilers and development libraries installed for each target CPU and OS. For example, on Ubuntu 12.04 for x86-64, install the following packages for each target:
|
||||||
|
|
||||||
|
* linux32: `sudo apt-get install g++-multilib libc6-dev-i386 lib32stdc++6`
|
||||||
|
* win32: `sudo apt-get install g++-mingw-w64-i686`
|
||||||
|
* win64: `sudo apt-get install g++-mingw-w64-x86-64`
|
||||||
|
* arm: `sudo apt-get install g++-arm-linux-gnueabi`
|
||||||
|
* armhf: `sudo apt-get install g++-arm-linux-gnueabihf`
|
||||||
|
|
||||||
|
Unfortunately, cross-compiling for Mac OS X is not currently possible; you must compile within OS X.
|
||||||
|
|
||||||
|
If you are using Mac and openjdk7 (or higher), use the following option:
|
||||||
|
|
||||||
|
$ make native LIBNAME=libsnappyjava.dylib
|
||||||
|
|
||||||
|
## Miscellaneous Notes
|
||||||
|
### Using snappy-java with Tomcat 6 (or higher) Web Server
|
||||||
|
|
||||||
|
Simply put the snappy-java's jar to WEB-INF/lib folder of your web application. Usual JNI-library specific problem no longer exists since snappy-java version 1.0.3 or higher can be loaded by multiple class loaders in the same JVM by using native code injection to the parent class loader (Issue 21).
