<div dir="ltr"><div dir="ltr">If it helps, we are using <a href="https://www.pgbouncer.org/">pgbouncer</a> to avoid opening a lot of connections to db. Pgbouncer acts as a db server for opensips with full workers connections and opens just a few (on demand) to real db server. It helps a lot when you have backup/standby opensips, not increasing those db connections. <br><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 3, 2020 at 9:13 AM Bogdan-Andrei Iancu <<a href="mailto:bogdan@opensips.org">bogdan@opensips.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Maybe we should consider (as future extension) the possibility to bundle <br>
