d962568e93 all: use %w instead of %s for wrapping errors in fmt.Errorf
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .
See https://blog.golang.org/go1.13-errors for details.

a72f18e821 lib/{storage,mergeset}: further tuning of compression levels depending on block size
This should improve performance for querying newly added data, since it can be unpacked faster.

e3b18ca1ab lib/mergeset: skip createing temporary part objects when merging source inmemory parts
This should reduce CPU usage when adding new entries to inverted index.
This should alos prevent from creating stalled cleaner goroutines for the created temporary parts,
since they were never closed.

This should fix the following issue: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/316 .

347aaba79d lib/{storage,mergeset}: use time.Ticker instead of time.Timer where appropriate
It has been appeared that time.Timer was used in places where time.Ticker must be used instead.
This could result in blocked goroutines as in the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/316 .

3694efd005 lib/{mergeset,storage}: log info message when both source and destination part paths from txn are missing during startup

639967db59 lib/{mergeset,storage}: make sure pending transaction deletions are finished before and after runTransactions call.
`runTransactions` call issues async deletions for transaction files. The previously issued transaction deletions
can race with the next call to `runTransactions`. Prevent this by waiting until all the pending transaction
deletions are funished in the beginning of `runTransactions`. Also make sure that all the pending transaction
deletions are finished before returning from `runTransactions`.

b9616c017f lib/{mergeset,storage}: remove transaction files only after the mentioned dirs are really removed
This should fix the issue on NFS when incompletely removed dirs may be left
after unclean shutdown (OOM, kill -9, hard reset, etc.), while the corresponding transaction
files are already removed.

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

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`.

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.
