Krasi Georgiev	520ab7dc53	re-add the missing prometheus_tsdb_wal_corruptions_total (#473 ) closes https://github.com/prometheus/tsdb/issues/471 after implementing the new WAL this metric was missing so adding it again. Also added it in a test to make sure it works as expected. Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	6 years ago
Krasi Georgiev	79869d9a4d	fix race for minValidTime (#479 ) it happens when truncating the WAL and another goroutine creates a new Appender() Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	6 years ago

Krasi Georgiev	48efdf8b81	refactor NewSegmentsRangeReader to take multi WAL ranges (#449 ) * refactor NewSegmentsRangeReader to take multi WAL ranges In case of an error when checkpointing the WAL the error doesn't show the exact WAL index that is corrupter. this is because it uses MultiReader to read multiply WAL files. This refactoring allows the NewSegmentsRangeReader to take more than a single WAL range and it reads all of the ranges by iterating each one. this changes the logs from create checkpoint: read segments: corruption after 4841144384 bytes:... to create checkpoint: read segments: corruption in segment data/wal/00017351 at 123142208: ...

Krasi Georgiev	0493efb7c5	repair wal when the record cannot be decoded (#453 ) * repair wal when the record cannot be decoded Currently repair is run only when the error happens in the reader. A corruption can occur after the record is read and when it is decoded. This change wraps the error at decoding as a CorruptionErr as this error is expected to trigger a repair.

Krasi Georgiev	5a9ddeecef	fix lint errors (#439 ) unexported NewMemTombstones as this returns unexported memTombstones type which will not be shows in godoc. Added missing comments for exported methods. Removed unused RecordLogger,RecordReader interfaces. Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	6 years ago

Brian Brazil	c7e7fd355e	Only send WAL read workers the samples they need. Calculating the modulus in each worker was a hotspot, and meant that you had more work to do the more cores you had. This cuts CPU usage (on my 8 core, 4 real core machine) by 33%, and walltime by 3% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
Brian Brazil	a64b0d51c4	Precalculate memSeries.head This is read far more than it changes. This cuts ~14% off walltme and ~27% off CPU for WAL reading. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
Brian Brazil	d8c8e4e6e4	Keep local cache of ids. With the various goroutines running, the locking in getByID is notable. This cuts cpu usage by ~25% and walltime by ~20%. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago

Benoît Knecht	1e1b2e163d	Make interval overlap comparisons more explicit Blocks are half-open intervals [a, b), while all other intervals (chunks, head, ...) are closed intervals [a, b]. Make that distinction explicit by defining `OverlapsClosedInterval()` methods for blocks and chunks, and using them in place of the more generic `intervalOverlap()` function. This change also fixes `db.Querier()` and `db.Delete()`, which could previously return one extraneous block at the end of the specified interval.
