Looking at my git history, I've been happily running InfluxDB for years. However nearing the end of 2021, after long time of peaceful coexistence among my monitoring services, some more or less pressing problems emerged:

• The long-term future of InfluxDB 1.x is uncertain, it's pretty clear that I'll have to migrate to 2.x in foreseeable future.
• Memory usage becomes a bit problematic. Well, that's quite an understatement. The container ran out of memory frequently and I had to bump up the limit couple times already. Despite that, I can't even graph longer time spans without getting InfluxDB OOM killed and it's at this stage by far the most memory intensive service I ran. There are presumably some improvements in InfluxDB 2.x that could help here.

The solution seems pretty obvious, however in the end this post isn't really about InfluxDB.
