evalRollupFuncNoCache() may return time series with identical labels (aka duplicate series)
when performing queries satisfying all the following conditions:
- It must select time series with multiple metric names. For example, {__name__=~"foo|bar"}
- The series selector must be wrapped into rollup function, which drops metric names. For example, rate({__name__=~"foo|bar"})
- The rollup function must be wrapped into aggregate function, which has no streaming optimization.
For example, quantile(0.9, rate({__name__=~"foo|bar"})
In this case VictoriaMetrics shouldn't return `cannot merge series: duplicate series found` error.
Instead, it should fall back to query execution with disabled cache.
Also properly store the merged results. Previously they were incorrectly stored because of a typo
introduced in the commit

vmselect performs the following tasks:
-
Splits incoming selects to tasks for
vmstoragenodes and issues these tasks to all thevmstoragenodes in the cluster. -
Merges responses from all the
vmstoragenodes and returns a single response.
The vmui directory contains static contents built from app/vmui package with make vmui-update command. The vmui page is available at http://<vmselect>:8481/select/<accountID>/vmui/.
