Thanks for the post . Is there any practical scenario for such frequent action. Also in such frequent operation Salesforce limit of 100 scheduler in a org might reach soon?
Hi Manish,
I have come across multiple requests from the clients regarding the same. However, it’s always best to say no with some other options for example calling the same batch again from the finish after 5 min. (There is a method inside the System class that can schedule the batch to execute after certain minutes ).
Yes the limit will exceed soon, so we need to keep in mind while scheduling these frequent batch apex.
