MongoDB::ChangeStream - A stream providing update information for collections.
version v2.0.3
$stream = $collection->watch( $pipeline, $options );
while(1) {
# This inner loop will only iterate until there are no more
# changes available.
while (my $change = $stream->next) {
...
}
}
This class models change stream results as returned by the "watch" in MongoDB::Collection method.
$change_stream = $collection->watch(...);
$change = $change_stream->next;
Waits for the next change in the collection and returns it.
Note: This method will wait for the amount of milliseconds passed as "maxAwaitTimeMS" to "watch" in MongoDB::Collection or the server's default wait-time. It will not wait indefinitely.
