What is the maximum number of nodes that can be spawned using MNI?

The maximum number of nodes that can be spawned using Multi-Instance (MNI) in Appian is indeed 1000. Multi-Instance nodes are designed to allow a process to iterate over a collection of items, executing a specified sub-process for each item in that collection. This capability is particularly useful for operations that need to be performed on multiple records or entities without requiring a completely separate subprocess for each.

Setting a limit of 1000 nodes is indicative of balancing performance and manageability within the platform. If users need to work with collections larger than this number, it is often recommended to rethink the data processing strategy or break down the collections into smaller batches. This keeps the system performing optimally and prevents unnecessary strain on the process execution engine. Thus, understanding this limit is crucial for designing efficient processes in Appian.
