Cdm Cache uses a lot of disk space
Added by Patrick Plitzner about 5 years ago.
Updated about 2 years ago.
Description
Recently Tilo experienced a sudden system freeze when his main partition went from ~3GB free disk space to 100% full in seconds.
We found out that it was the CDM cache file that took +2,5GB disk space.
This is not a problem per se but the users should be informed about the cache and it should be reflected in the specs.
He was working in the Additivity context with the FeatureTreeEditor, TermEditor, DatasetEditor and the CharacterMatrix.

- Description updated (diff)
The description states that the increase of diskspace usage happened in seconds "free disk space to 100% full in seconds."
If this is true it should be quite easy to pin down the cause for this cache growth.
- Tags changed from performance to performance, ehcache
- Tags changed from performance, ehcache to performance, ehcache, matrix
We should have a look on this with the new implementation because the matrix worked with descriptions and descriptiveDataset as cdm objects and now everything comes as dtos.

As this was not only a problem of the matrix the new DTOs for the matrix may reduce the problem but not fully resolve it.
A further (or maybe even final) step could be the solving of #9838 which is seems to be partly (of fully) a duplicate for this ticket).
- Status changed from New to In Progress

Please review if this is maybe fully fixed already or will be fixed after fully solving #9842.
Please pass to me after review.
