bd1cf053f6 app/vmselect/promql: add increases_over_time and decreases_over_time functions 
`increases_over_time(q[d])` returns the number of `q` increases during the given duration `d`.
`decreases_over_time(q[d])` returns the number of `q` decreases during the given duration `d`.

adc18c3ee6 lib/{mergeset,storage}: do not cache inverted index blocks containing tag->metricIDs items

73ac7b8dd6 app/vminsert/netstorage: make sure the conn exists before closing it in storageNode.closeBrokenConn 
The conn can be missing or already closed during the call to storageNode.closeBrokenConn.
Prevent `nil pointer dereference` panic by verifying whether the conn is already closed.

Thanks to @CH-anhngo for reporting the issue.

c64fb91a43 lib/uint64set: optimize Set.AppendTo 2019-09-25 00:34:31 +03:00
Aliaksandr Valialkin
de0e4eee2c lib/storage: create and use lib/uint64set instead of map[uint64]struct{} 
This should improve inverted index search performance for filters matching big number of time series,
since `lib/uint64set.Set` is faster than `map[uint64]struct{}` for both `Add` and `Has` calls.
See the corresponding benchmarks in `lib/uint64set`.

d2ed8cb0b2 lib/storage: generate the first tag->metricIDs item in a mergeset block with a single metricID 
The first item from each mergeset block goes into index (lib/mergeset.blockHeader),
so it must be short in order to reduce index size.

7d13c31566 lib/{storage,mergeset}: merge tag->metricID rows into tag->metricIDs rows for common tag values 
This should improve lookup performance if the same `label=value` pair exists
in big number of time series.
This should also reduce memory usage for mergeset data cache, since `tag->metricIDs` rows
occupy less space than the original `tag->metricID` rows.

7e0c6d4ca6 lib/storage: optimize selecting all the metricIDs by scanning MetricID->TSID entries instead of tag->MetricID entries 
The number of MetricID->TSID entries is smaller than the number of tag->MetricID entries
and MetricID->TSID entries are usually shorter than tag->MetricID entries.
This should improve performance when selecting all the metricIDs.
