It seems that the table manager is chatty when running Loki using boltdb.

see transcript.

I am seeing the same issue with a small local instance of loki, which I've recently upgraded to 1.3.0. Every 2 minutes it spams the logs: in fact loki itself is generating more logs than the rest of the source devices!

It appears to be creating tables with the same index_XXXX each time, although not always all of them:

root@loki:/var/log# grep loki-linux-amd64 syslog | grep 19:42: | grep "creating table" | wc -l
61
root@loki:/var/log# grep loki-linux-amd64 syslog | grep 19:44: | grep "creating table" | wc -l
68

Setting -log.level=warn is the only workaround I currently have. I think that pushing these messages down to "debug" level might be better.

Cheers,

Brian.

P.S. Example of one spew:

The only way I can see to suppress these is to run with -log.level=warn

The log is hammered with lines like:

I think this needs reopening. I'm constantly seeing these logs every second. I'm unsure if this is normal behaviour or if it is stuck in a loop. Either way, it seems a little excessive for info level logging.
