<p> First, for general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. We currently support streaming if you are running MySQL 5.1 with the PBXT and PBMS storage engines. Moreover, only PBMS 0.5.04 is supported.</p> <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
<ul>
<li>PBMS BLOB Streaming Daemon for MySQL (0.5.15 or later)</li>
<li>Streaming enabled PBXT Storage engine for MySQL (1.0.11-6 or
later)</li>
<li>PBMS Client Library for MySQL (0.5.15 or later)</li>
<li>PBMS PHP Extension for MySQL (0.1.1 or later)</li>
</ul>
<p>Here are details about configuration and operation:</p>
