confluence attachments data
Asked by Trevor Hunt:

Where is the attachments data stored in confluence 5.9.4? I've assumed ownership of a new instance and I can't find the "ATTACHMENTS" table for the life of me. Am I going insane? See the table list below - I was logged in as the application user when I pulled the list.

body: Thanks, gents. ATTACHMENTDATA is empty and ATTACHMENTS_BACKUP is was apparently a snapshot taken prior to an upgrade. The max date on any of the columns is February.

We're on 5.9.x so Doug gets a point for being the closest! :wink:

I did find the solution!
UNDERLYING STORAGEAs of 5.7 attachment metadata that was stored in the `attachment` table will transition to the `content` and `contentproperties` tables. All Confluence APIs will transition to referencing these objects from the new tables. As an API consumer, you should not be affected by this change. If your plugin directly references the `attachment` table, you'll need to transition it to use the public API manager, `AttachmentManager,` to avoid any issues. Attachments that were stored in the database (legacy) will still be in the `attachmentdata` table.

body: Have a look at these ones!

```
 ATTACHMENTDATA                 || ATTACHMENTS_BACKUP
```

Cheers
