Thank you very much for you help.
Actually I need to support Elastic Search Engine (ESE) for a large data
mining project integrated with Kamailio. The easiest way i thought to
achieve that was to use Perl VDB or else i have to write up ESE module for
kamailio myself.
I am going to test the changes you did to PERL VDB module and will fix up
any minor issues to make it working again. Kindly do not remove it from
kamailio repo. I am not expert in Kamailio APIs but have good coding
experience with C / C++, so I am willing to provide maintenance and bug
fixes for the module with your help on API side if needed.
Also, the new DB API for Kamailio, is there any documentation related to it
available online. I want to study it and may be add later on a separate
kamailio module exclusively for ESE for better performance and features
specific to ESE.
Thank you.
