NAME

MongoDB::ChangeStream - A stream providing update information for collections.

VERSION

version v2.0.1

SYNOPSIS

    $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) {
            ...
        }
    }

DESCRIPTION

This class models change stream results as returned by the "watch" in MongoDB::Collection method.

STREAM METHODS

next

    $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.
