InfluxDB Breaking changes
- 👍 To better support templating, fill(0) and group by time low limit some changes has been made to the editor and query model schema
- Currently some of these changes are breaking
- ⚡️ If you used custom condition filter you need to open the graph in edit mode, the editor will update the schema, and the queries should work again
- ⚡️ If you used a raw query you need to remove the time filter and replace it with \$timeFilter (this is done automatically when you switch from query editor to raw query, but old raw queries needs to updated)
- 🚚 If you used group by and later removed the group by the graph could break, open in editor and should correct it
- ⚡️ InfluxDB annotation queries that used [[timeFilter]] should be updated to use \$timeFilter syntax instead
- ⚡️ Might write an upgrade tool to update dashboards automatically, but right now master (1.8) includes the above breaking changes
InfluxDB query editor enhancements
- Issue #756. InfluxDB: Add option for fill(0) and fill(null), integrated help in editor for why this option is important when stacking series
- 👍 Issue #743. InfluxDB: A group by time option for all queries in graph panel that supports a low limit for auto group by time, very important for stacking and fill(0)
