Summary:

Opening a file with linked data shows several 'Loading embedded data' messages that slow down the opening of the file.

 

Description:

When opening a file that uses linked data and you use calculated columns you may see something similar to this in the Open file dialogue after clicking 'Show Details':

11:48:08 Loading item from Library.
11:48:34 Loading document.
11:48:39 Unpacking compressed data.
11:48:44 Handling compatibility.
11:48:46 Loading embedded data.
11:48:47 Loading embedded data.
11:49:14 Unpacking compressed data.
11:49:20 Opening connection to database...
11:49:22 Reading data from data source...
11:49:22 Reading data.
11:49:44 Configuring document.
11:49:45 Opening connection to database...
11:49:45 Reading data from data source...
11:49:45 Reading data.
11:49:54 Configuring document.
11:50:26 Calculating column.
11:50:27 Calculating column.
11:50:34 Calculating column.
11:50:34 Configuring document.
11:50:35 Compressing data.
11:50:36 Compressing data.
11:50:37 Configuring document.
11:50:37 Done

Even though you have saved the file using linked data you see 'Loading embedded data.' when opening the file

 

Symptoms:
 
Files with linked data may open slower than normal and you see multiple 'Loading embedded data.' messages in the File open dialogue.
 
Cause:
Data that is loaded into the analysis when saving will automatically be embedded in the file if you have calculated columns, even though you choose to use linked data.
 
Resolution:
 
There is a preference - CacheCalculatedColumnsDefaultBehavior - that can be used to disable embedding data when doing calculations.  

1. Go to Tools menu->Administration Manager->Preferences

2. Select the group you want to apply this for and chose Application->Persistence and set CacheCalculatedColumnsDefaultBehavior to 'False'.

Note: Only Spotfire Administrators (i.e. users with both the TIBCO Spotfire Administrator license and membership in the Administrator group) can do this.
