How many documents can we store in Appian?

Question

I need to know if there are any limitations with the number of documents we store in Appian - both the total number, but also also in terms of how we store them. 
 We currently use the standard configuration with 3 ACCDOC folders. If we intend to store a high number of documents (many millions) should this be configured differently to avoid performance issues? 
 thanks

There is no limit to the number of documents that can be stored in Appian. Other than making sure you have enough disk space and memory, there isn't anything special you need to do in terms of configuration. In terms of performance, you will want to be mindful in how you design your applications to ensure that the design is appropriate for your intended usage. For example, if you have 100 million documents, and then you give users access to a field that searches all 100 million documents... that search is, of course, going to be slower than it would be on a site that only had 10,000 documents. On a similar note, it's important to remember that documents are design objects (just like process models, interfaces, etc), so if you try to search through all of your design objects (for example, from the objects tab in Appian Designer), you would want to exclude documents from that search. 
 
There are installations running in production today that are taking advantage of Appian's document management capabilities to handle millions of documents or more. As long as you keep some basic considerations in mind, storing and managing large numbers of documents shouldn't be an issue.
