Constant database updates and disk writes

[cleoold]

Jellyfin works very great for me except some minor annoyances that bug me a lot of time. When I play music (e.g. on the Web UI), I observe that my disk is constantly written with something like 10-20KB/s, even when the music is paused. I found these files are modified every 10 seconds:

• library.db
  
• library.db-shm
  
• library.db-wal
  
• jellyfin.db-shm
  
• jellyfin.db-wal
  

(surprisingly jellyfin.db was not updated that often) I confirmed it because every time I listed the directory they always had modified date as current time.

I saw these logs every 10 seconds too after turning on the debug logging:

Code:

Ouch, they don't show DB though. I may believe it's monitoring the playback progress and somewhat storing it to the db (for group play purpose?). Given I use direct play to avoid transcoding on hard drives, My question is can I further disable these playback-related disk writes, so I get ZERO disk writes when issuing read-only ops (i.e. direct playing media) to save my drives (I'm kind of paranoid when it comes to storage longevity lol)? Is doing the logging a must, or some important things will break?

Same for activity logs: I got concrete answer from GH issues that it (or part thereof) cannot be disabled.

I'm a bit tech-oriented, so if either cannot be done of out the box, can anyone give me pointers on where I should look to modify the code myself?

PS: blocking requests from browser to /Sessions/Playing seems to do some job by removing the tiny writes, but does not feel right to me so configuring the server is preferred.
