Hi Alireza, Other approach I can think of is database triggers (can impact performance based on the jobs frequency).
Take a look at the async_job table's insert and update operations which are performed on creating a new job (job status 0) and updated when job is complete with non-zero job status (1 - success, 2 - failed, 3 - cancelled) respectively. https://dev.mysql.com/doc/refman/5.6/en/faqs-triggers.html [a trigger could invoke the sys_exec() UDF.] Some ref for sys_exec UDF implementation below => http://kedar.nitty-witty.com/blog/tag/sys_exec http://bernardodamele.blogspot.com/2009/01/command-execution-with-mysql-udf.html - Suresh On Sat, Feb 23, 2019 at 2:05 AM Alireza Eskandari <astro.alir...@gmail.com> wrote: > Async jobs is not my concern. > Imagine that you have a firewall that is not integrated with CS and you > want to insert new roles in it each time a new VM is created. > In this case you need a hook that triggers an external script to configure > the firewall. > Pulling is time and resource consuming and its effect is not instant. > > On Fri, Feb 22, 2019 at 8:02 PM Anurag Awasthi < > anurag.awas...@shapeblue.com> > wrote: > > > Hi Alireza, > > > > Could you elaborate a more on the use case you have in mind?
