Does anyone now how one correctly defines write concern when doing $collection->insert_one()? It seems that I should do something like
$collection->insert_one({....},
{
writeConcern => MongoDB::WriteConcern->new(
{
w => 'majority',
j => 1,
wtimeout => 10000,
}
}
);
That should be waiting till data is copied to majority of hosts in replica set, so it shall be slower, than default write concern. In practice though I get the same speed of writing as with w => 0 and j => 0. Plus replication looses data if I kill primary host. Do I miss something?
I'm using mongodb 3.2.12 and module MongoDB version 1.6.1

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
