Model size limits

Issue/Introduction

Regarding 2E model size, some of our biggest models are 12-13 GB. Each of these large models have multiple user spaces already (i.e.: YOBJTBLSPC, YOBJTBLSP2). Is there a known max size for a 2E Model? 

For example, is there a threshold when we should start thinking to split the Model into another one to control the size growth? The number of user spaces seems to be limited to 20, based on the command YDLTOBJTBL.

Resolution

There is no documented known maximum size for a 2E model.

The maximum size allowed for a user space is 16 MB.  

When the size of a user space exceeds 16MB, 2E automatically takes care of creating a new user space.

The maximum number of user spaces allowed for a model is 20.

So the maximum size of a 2E model can be mentioned in terms of number of userspaces, which is 20.

There is no one single new object creation which counts towards creation of a new userspace. It is generally a combination of various factors like new files, fields, the corresponding relations etc.

The only important fact to look at is the maximum size of user space being 16 MB.

It is a good idea to keep track of count of each type of object. As the model size increases, via the addition of model objects, when a new user space gets added, the count of objects could act as a possible pointer to track.

The user space only contains pointers to content within the model files and certain critical information from them. The entire model information is not loaded into the user space. The size of 12-13 GB is taking into account the information contained in all of the model object files. So there is no direct link between the model size and the number of user spaces that it should directly translate to.
