We are using influxDB to calculate SLO performance. Currently, among other things, we process about 30M ELB logs entries into influxdb per day; it handles this easily of course. Here are some musings for those interested based on 0.9:<p>Wins:<p>* The new storage engine is very, very cool. Would love to work on this thing. It's fast and space efficient.<p>* Built in support for time bucketing GROUP's<p>* Grafana integration is pretty good<p>* Writes come back after the data is stored; makes it easy to create durable, idempotent processing pipelines.<p>Woahs<p>* Unable to combine measurements in the same query; needs ETL with continuous queries or external tools<p>* No support for subqueries; more ETL<p>* Stream processing is a little lacking -> can't group on values and high cardinality tags make the DB explode; high cardinality is being worked on but IDK how high it will go, plus I mean the storage engine serves up streams of time-sorted data so samza that stuff up.<p>* Random crashes but the DB gets along fine when it comes back up<p>* Compactions use LOTS of RAM. Supposedly this can be tweaked and has been improved for 1.0<p>* Backfill queries with lots of points seem to use a crazy amount of RAM when bucketing on narrow time windows<p>Overall it's chugging along quite well. Most of the query limitations we are able to solve with a combination of continuous queries and AWS lambda functions kicked off by CloudWatch Events.
