First-time Purges

First-time Purges

Purging generates journaling. If you purge a large volume of data, the resultant journaling can consume a large amount of disk space. To conserve disk space, you can adopt the following approach the first time you purge management data:

1. Switch to the namespace where you want to purge data.

2. Navigate to the Interoperability > Manage > Purge Management Data page.

3. Set the purge parameters so that a relatively small amount of data is purged.

   For example, you can set Do not purge most recent to a relatively large number. For more information, see Settings for Purging Data.

   Caution:

   Purges are irreversible and can lead to unintentionally orphaned data or the loss of unresolved requests. Consequently, InterSystems recommends that you carefully review the description of each setting before proceeding.

4. Click Start Purge.

5. Gradually decrease the Do not purge most recent value and purge additional data until you have purged a sufficient amount of data.
