After running InfluxDB in production for a bit more than year, here's some issues from top of my mind we ran have into: # Common - All: Various documentation issues - Including versioning in the documents - Influx/Kapacitor: Cannot join values in Influx, but you can Kapacitor (but not dynamically) - Available in InfluxDB 1.6. now! # InfluxDB - Influx: GroupTag not grouping https://github.com/influxdata/kapacitor/pull/1773 https://github.com/influxdata/kapacitor/pull/1773 - Influx: last() is really slow https://github.com/influxdata/influxdb/issues/8997 https://github.com/influxdata/influxdb/issues/8997 - Influx: Cannot update / edit tags https://github.com/influxdata/influxdb/issues/3904 https://github.com/influxdata/influxdb/issues/3904 - Apparently you can have tags and fields with the same names which bump up the query times by 1000x times, without ever knowing what's wrong (fixable by adding ::tag to the value) - Cannot incrementally restore incrementally backed up databases (we made a script to do that) https://github.com/motleyagency/influxdb-incremental-restore https://github.com/motleyagency/influxdb-incremental-restore # Kapacitor - Kapacitor does not support subqueries - Kapacitor does not (properly) support queries from multiple measurements - Cannot have field and tags with same name - Cast syntax doesn't work either (https://github.com/influxdata/influxdb/pull/6529 https://github.com/influxdata/influxdb/pull/6529) # Telegraf - Telegraf: Telegraf HTTPJson plugin does not support custom timestamps # Chronograf - The TickScript editor sometimes hangs for good and requires Chronograf restart - Minor: No up-to-date syntax highlighting for TickScript in any common editors That said we most likely would have ran into similar issues with out time series databases and I applaud their effort to keep InfluxDB open source.
