The Apache Synapse team is pleased to announce the project is releasing 1.1 of the Open Source Enterprise Service Bus (ESB).

Apache Synapse offers a wide range of connectivity, including HTTP/S, JMS, (S)FTP, SOAP, WS-ReliableMessaging and WS-Security. The project has been designed to allow administrators to support advanced functionality such as load-balancing, throttling, and failover without writing code.

The new Apache Synapse 1.1 release includes many enhancements based on feedback from users, including

  • Apache VFS based file transport – supports File System, FTP, SFTP, JAR, ZIP, TAR, GZIP, Mime
  • Scheduled Task support makes it simple to run repetitive tasks
  • XQuery mediator – simplifies XML transformation with the XQuery standard
  • POJO Command mediator – allows the creation of message-independent mediation logic
  • DB Report and DB Lookup mediators – support message augmentation and database logging
  • Cache and Throttle mediators/enhancements – improve performance and manage load on existing services
  • Split/Clone/Aggregate mediators – support batch processing of large messages
  • Improved logging and tracing support

With asynchronous support for HTTP and HTTPS, Apache Synapse has very high scalability under load, supporting thousands of concurrent connections even with limited threads. Combined with streaming XML support, Apache Synapse has class-leading performance results.
