| <div class="wiki-content maincontent"><h2>Can I send really large files over ActiveMQ</h2> |
| |
| <p>The answer is yes. </p> |
| |
| <p>If you are using ActiveMQ 4.2 or later we highly recommend you use <link><page ri:content-title="Blob Messages"></page></link> which implements an out of band transport of the messages; it allows the files to be hosted on external http/ftp sites if required and can support either direct publisher <-> subscriber communication or publisher -> broker/file server -> consumer messaging.</p> |
| |
| <p>For 4.1 or ealier large file transfer is achieved using <link><page ri:content-title="JMS Streams"></page></link>. </p> |
| |
| <p>Normally the JMS API expects the entire JMS messsage to reside in the client side memory; however using <link><page ri:content-title="Blob Messages"></page></link> or <link><page ri:content-title="JMS Streams"></page></link> allows you to send and receive arbitrarily large files with very low RAM overhead.</p> |
