**Your software** My Mautic version is: 3.1 My PHP version is: 7.2 **Your problem** My problem is: I have noticed that my DB is getting huge (okay we have over 1M contacts) but part of the problem is there are hourly imports coming into the DB and I see that both the lead\_event\_log and imports table are rather big. Does anyone know if anything bad will happen if I purge the import table totally, and remove all entries from leads\_event\_log table where properties like “%file%” ---

This is what my DB is looking like: email\_stats | 16056.08 | | audit\_log | 3820.63 | | lead\_event\_log | 2837.56 | | campaign\_lead\_event\_log | 2698.25 | | leads | 1434.94 | ---

This is a very hard question. I have the answer, but you not gonna like it. Will you need tracking data? - If not, why to use Mautic? - If yes you’ll need to scale this up. More info: [Login to Meetup | Meetup](https://www.meetup.com/Mautic-Meetup-Lagos/events/272511292/) Or check this: > [@Delete old rows from email\_stats table without breaking front-end](https://forum.mautic.org/t/delete-old-rows-from-email-stats-table-without-breaking-front-end/11201/3): > > Hi Ruth: Thanks so much for your reply. I’ve reviewed the issue as reported on GitHub. I think I’ll use the SQL Update statements as provided in that issue till hopefully a future release addresses the issue. I think any implementation of size makes it quite costly to run given the disk space requirements to handle how it presently grows the email\_stats table. I would imagine the [mautic.com](http://mautic.com) folks are experiencing some pain on this issue, ya? Thanks again! Bob H. ---

Is this causing space issues, or is this hindering your performance? Reason I ask is there seems to be some relief on the way. (At least indirectly) > ---

Thanks @joeyk going to check those articles out. We need tracking, but not for all the records and for so long back, @EJL - it is performance related. going to check out your links as well. Thanks to both above
