title: Save file as blob in MYSQL database or as file path
body: <p>I know these question is one of the frequently asked, but I need your help for a specific case. </p>
  
  <p>I am developing an application, where some users can add orders, and some users can perform these orders. These orders are very specific, so only limited number of users can add them. </p>
  
  <p>Than, three documents are generated for each order. The size of each document doesn't exceed 1MB so I am going to save them in my DB as blobs, but I don't know what will happen in the future, the size of the documents may be significantly increase (for example: 5MB). What should I do? and Why?  Save them as blobs or save them as file path. </p>
  
  <p>For example: Is it good practice to keep saving 5MB files as blobs in DB, or is it better to save them as file path from the beginning(If I know this can happen
  ), or save them as blobs and if they increase than change it.</p>
  
  <p>For this project I am using <code>digitalocean</code> server. </p>
