That's honestly not that big compared to other users' databases. Nothing I can do about it.

but it keeps getting bigger it's 717 MB right now from 649 to 717 MB in 1 hour

739 MB in a couple of minutes ! would be great if you can install nzbhydra2-5.1.8-windows and reproduce

[theotherp]

Not to be too flippant about this but come back when it's a couple of gigabytes. Unfortunately this is a known problem with the database library. When you restart hydra it should get smaller because then it will try to compress it. You can also try enabling advanced options and increasing the time for this (something with database compression or shutdown time).

... mine is 45G

was 46g for a couple of days, just restarted it, and it went from 46 to 45g..

i do care about the stats.. its actually the main reason i use it. i want it to help me decide which indexers are preforming the best, so i know which ones are worth renewing. if i delete the file, will it regenerate? i dont mind loosing search history, i just want the stats.. are they maintained in another file?

Yes, the database will be recreated on the next start. But the stats are created on the fly from the history. Can you please upload your debug infos zip?

nzbhydra-debuginfos-2023-09-19-15-10.zip

Attached

[MicMillon]

Hey, any feedback from the attached debuginfo file?

i'd really like to downsize that database...

[theotherp]

Try creating a backup. Does that work? Is the file in there so big as well? If it's smaller just replace the existing one with the one from the backup while hydra is down. See if it stays smaller.

[MicMillon]

Hey, so i tried that.. created the backup. shutdown the container, extracted the 19g nzbhydra.mv.db file from the backup, replaced the 45g file in the /appdata/nzbhydra/database directory, and restarted the hydra container. it came up, with my data there. with the database sitting around 20gb... came back a day or two later, and now its back up to the same 45g as before...
