This returns an estimate in MiB of the total storage occupied by the saved JSON data

SELECT SUM(LENGTH(source))/1024/1024 FROM source_store
|

SELECT ROUND(CAST(SUM(pgsize) AS REAL)/(1024.0*1024.0), 2) FROM dbstat WHERE name='source_store'

### Deleting JSON logs ###
|
||||
|
||||
You can delete the stored JSON whenever you want. It is adviced that you also set all `source_id` references to 0 in order to avoid wrong references to the new JSON logs getting stored in the future:
|
||||
|
||||
```
|
||||
UPDATE items SET source_id=0;
|
||||
UPDATE fame_list SET source_id=0;
|
||||
UPDATE icons SET source_id=0;
|
||||
UPDATE shop_snapshots SET source_id=0;
|
||||
DROP TABLE IF EXISTS source_store;
|
||||
VACUUM;
|
||||
```
