After remaining idle on the server for some amount of time, cursors, by
|
|
default, "die." This is generally the behavior one wants. The database
|
|
cleans up a cursor once all of its results have been sent to the client,
|
|
but if the client doesn't request all of the results, the cursor will
|
|
languish there, taking up resources. Thus, after a few minutes, the cursor
|
|
"times out" and the database assumes the client has gotten everything it
|
|
needs and cleans up its the cursor's resources.
|
|
</para>
|
|
<para>
|
|
If, for some reason, you need a cursor to hang around for a long time, you
|
|
can prevent the database from cleaning it up by using this method.
|
|
However, if you make a cursor immortal, you need to iterate through all of
|
|
its results (or at least until <methodname>MongoCursor::dead</methodname>
|
|
returns &true;) or the cursor will hang around the database
|
|
<emphasis>forever</emphasis>, taking up resources.
