Calling Process Flow on click of Button or link: Is it possible to call a proces

Hello Is there any way, in Records, Where the number of records available in DB, we need to have asynchronous process to be running at backgroud, Our use case is, if any status is changed then it should post a event to feed.
Note: Some of the records are appian initiated and some of them are directly from DB.

@vinitl Could you please expand the use-case much more? It will help the practitioners to give the solution that best fits your requirement.

Hello,

Ex: We have 40 records in db, and the record is of type service backed.
Out of 40, 20 records data are from appian initiated, and 20 are already exsisting in Database. Now, for 20 records(which are from appian), i have implemented a logic, where we have a process for those 20 records in asynchronous, which checks the status every 1 day, and if status is changed then we are posting a event to feed to the follower of the record.
Whereas for other 20, I am just wondering how can I initiate a process to make sure that if the status is changed then I can post event to the feed.
Also, is there a way where we can get the list of users who have followed the record
