This avoids requests to allocate new ids when new objects are stored on a client.</p> <p> </p> <p>When a new object is created on a client, the client should contact the server to get the next available object ID. PrefetchIDCount allows to specify how many IDs should be pre-allocated on the server and prefetched by the client. This method helps to reduce client-server communication.</p> <p>PrefetchIDCount can be tuned to approximately match the usual amount of objects created in one operation to improve the performance.</p> <p>When the PrefetchIDCount is one, the client will have to connect to the server for each new objects created. On the other hand,, when the PrefetchIDCount is bigger than the amount of new objects the database will keep unnecessary preallocated ids. </p> <p>The default PrefetchIDCount is 10.</p> <script type="text/javascript" src="../../SkinSupport/MadCapBodyEnd.js"> </script> </body> </html>
