I am trying to figure out the maximum size of attachment in a file and ArcSDE geodatabases while working on a project specification details. I am not able to find these figures documented by Esri anywhere.
Running own tests, it seems as a file geodatabase has a limit of ca 600MB per file that is being attached. When trying to attach everything that is larger than 600MB, I am getting an error (where
Points3D is the name of the feature class I am trying to attach a file to).
Just to see whether it is a file geodatabase only limit, I have run some tests with a SQL Server enterprise geodatabase and here I am getting stuck at somewhere between 700 and 800MB and either get the same error message (except that instead of the feature class name I have my SQL Server database filegroup name) or have ArcMap unexpectadly crashed and closed.
What is the official/documented maximum file size limit that one can upload to an Esri file geodatabase? I also welcome comments if someone has succeeded uploading anything larger than 1GB to a geodatabase as an attachment.
