7b6623558f lib/storage: skip adaptive searching for tag filter matching the minimum number of metrics if the identical previous search didn't found such filter
This should improve speed for searching metrics among high number of time series
with high churn rate like in big Kubernetes clusters with frequent deployments.

f4252f87e6 app/vminsert: really fix #60
ReadLinesBlock may accept dstBuf with non-zero length. In this case the last line without trailing newline isn't read.
Fix this by comparing len(dstBuf) to 0 instead of its original length.

1458450dba app/vmselect/promql: return the correct time series from quantile
Previously arbitrary time series could be returned from `quantile`
depending on sort order for the last data point in the selected range.

Fix this by returning the calculated time series.

This may be useful for data back-filling, when the response caching

in the past.
