 [idealo.de](https://www.idealo.de/) is the leading price comparison website in Germany. We use Prometheus for metrics on our container platform.
 When we introduced Prometheus at idealo we started with m3db as our longterm storage. In our setup, m3db was quite unstable and consumed a lot of resources.
 
-VictoriaMetrics in poroduction is very stable for us and uses only a fraction of the resources even though we also increased our retention period from 1 month to 13 months.

   - `label_keep(q, label1, ... labelN)` for deleting all the labels except the given labels from `q`. For example, `label_keep(foo, "bar")` would delete all the labels except `bar` from `foo` series.
   - `label_copy(q, src_label1, dst_label1, ... src_labelN, dst_labelN)` for copying label values from `src_*` to `dst_*`. If `src_label` is empty, then `dst_label` is left untouched. For example, `label_copy(foo, "bar", baz")` would transform `foo{bar="x"}` to `foo{bar="x",baz="x"}`.

   - `label_transform(q, label, regexp, replacement)` for replacing all the `regexp` occurences with `replacement` in the `label` values from `q`. For example, `label_transform(foo, "bar", "-", "_")` would transform `foo{bar="a-b-c"}` to `foo{bar="a_b_c"}`.
   - `label_value(q, label)` - returns numeric values for the given `label` from `q`. For example, if `label_value(foo, "bar")` is applied to `foo{bar="1.234"}`, then it will return a time series `foo{bar="1.234"}` with `1.234` value.
 - `label_match(q, label, regexp)` and `label_mismatch(q, label, regexp)` for filtering time series with labels matching (or not matching) the given regexps.
