app/vmselect/netstorage: reduce tail latency during query processing 
Previously the selected time series were split evenly among available CPU cores
for further processing - e.g unpacking the data and applying the given rollup
function to the unpacked data.
Some time series could be processed slower than others.
This could result in uneven work distribution among available CPU cores,
e.g. some CPU cores could complete their work sooner than others.
This could slow down query execution.

The new algorithm allows stealing time series to process from other CPU cores
when all the local work is done. This should reduce the maximum time
needed for query execution (aka tail latency).

The new algorithm should also scale better on systems with many CPU cores,
since every CPU processes locally assigned time series without inter-CPU communications.

The inter-CPU communications are used only when all the local work is finished
and the pending work from other CPUs needs to be stealed.

app/vmselect/netstorage: pre-allocate 4 block references per each time series during querying 
Usually the number of blocks returned per each time series during queries is around 4.
So it is a good idea to pre-allocate 4 block references per time series

all: use metricsql.CompileRegexp instead of regexp.Compile for compiling regexps used in graphite queries 
This should speed up repeated queries, since metricsql.CompileRegexp returns regexps from the cache
on subsequent calls for the same input regexp.

app/vmselect/netstorage: consistently select the sample with the biggest value out of samples with identical timestamps 
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3333

This fix is based on https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3620 ,
but doesn't slow down the common case with merging replicated data blocks so significantly.

all: small improvements in error messages and command-line flag descriptions related to concurrency limiters 2023-01-07 00:12:24 -08:00

lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit 
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.

It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.
