> We also need to add features for backup & restore, bulk data import and export, and data deletes

Interesting to see that we at VictoriaMetrics also pay attention to these features. Backup and restore already works - see below. Bulk data import and export plus data deletes for arbitrary metrics selectors will be available soon.

It would be great if InfluxDB 2.0 would have instant snapshots as VictoriaMetrics already has - https://medium.com/@valyala/how-victoriametrics-makes-instan... .

Also glad to see that the future InfluxDB versions will support Prometheus exposition format and PromQL :)
