SeaweedFS Client For Java

Features

SeaweedFS is a simple and highly scalable distributed file system and started by implementing Facebook's Haystack design paper. SeaweedFS is currently growing, with more features on the way.

This Java client is encapsulates the functionality full of the SeaweedFS API and provides a simple interface.

For performance, we make some progress:

• Include Ehcache and used it for cached lookup volume.
• Include HttpClient Connection Pool for handle HTTP request.
• Volume server location load balance.
• Heuristic cache is used for fetch file stream.
• Auto switch leader server (master) at failover.

Quick Start

Maven

<dependency>
  <groupId>org.lokra.seaweedfs</groupId>
  <artifactId>seaweedfs-client</artifactId>
  <version>0.7.3.RELEASE</version>
</dependency>

Gradle

repositories {
    mavenCentral()
}

dependencies {
    compile('org.lokra.seaweedfs:seaweedfs-client:0.7.3.RELEASE')
}

Create a connection manager

FileSource fileSource = new FileSource();
// SeaweedFS master server host
fileSource.setHost("localhost");
// SeaweedFS master server port
fileSource.setPort(9333);
// Startup manager and listens for the change
fileSource.startup();

Create a file operation template

// Template used with connection manager
FileTemplate template = new FileTemplate(fileSource.getConnection());
template.saveFileByStream("filename.doc", someFile);
