The Cache Cleaner extension was released about a month ago. A couple of bugfix releases have brought it to a more polished state.
- in version 1.0.1, detection of missing checks was added so that admins can be informed if the extension is not yet or badly configured.
- in version 1.0.2, the process was improved to avoid useless delete operations. Indeed a lowlevel script is always comprised of two parts: an analysis of the actions to take and the actions themselves. In the case of the Cache Cleaner, the analysis phase counts how many records are going to be deleted for each table. Now these results are stored for the execution phase, so that the delete operation is skipped entirely for a given table if the analysis didn't find any records to clean up. This speeds up the execution of the script.
