beorn7	f20b84e816	flags: Improve doc strings for checkpoint flags	8 years ago
beorn7	f338d791d2	storage: Several optimizations of checkpointing - checkpointSeriesMapAndHeads accepts a context now to allow cancelling. - If a shutdown is initiated, cancel the ongoing checkpoint. (We will create a final checkpoint anyway.) - Always wait for at least as long as the last checkpoint took before starting the next checkpoint (to cap the time spending checkpointing at 50%). - If an error has occurred during checkpointing, don't bother to sync the write. - Make sure the temporary checkpoint file is deleted, even if an error has occurred. - Clean up the checkpoint loop a bit. (The concurrent Timer.Reset(0) call might have cause a race.)	8 years ago

beorn7	7199a9d9d4	storage: Guard against appending to evicted chunk Fixes #2480. For certain definition of "fixes". This is something that should never happen. Sadly, it does happen, albeit extremely rarely. This could be some weird cornercase we haven't covered yet. Or it happens as a consequesnce of data corruption or a crash recovery gone bad. This is not a "real" fix as we don't know the root cause of the incident reported in #2480. However, this makes sure the server does not crash, but deals gracefully with the problem: The series in question is quarantined, which even makes it available for forensics.	8 years ago
beorn7	3d12906286	storage: Guard against a corner case of data corruption Fixes #2475.	8 years ago
beorn7	4fcc73a04c	storage: Recover from corrupted indices for archived series An unopenable archived_fingerprint_to_timerange is simply deleted and will be rebuilt during crash recovery (wich can then take quite some time). An unopenable archived_fingerprint_to_metric is not deleted but instructions to the user are logged. A deletion has to be done by the user explicitly as it means losing all archived series (and a repair with a 3rd party tool might still be possible).	8 years ago

beorn7	ae286385fd	storage: Check for negative values from varint decoding Sadly, we have a number of places where we use varint encoding for numbers that cannot be negative. We could have saved a bit by using uvarint encoding. On the bright side, we now have a 50% chance to detect data corruption. :-/ Fixes #1800 and #2492.	8 years ago

Björn Rabenstein	50e4f49b7e	Merge pull request #2561 from prometheus/beorn7/storage2 storage: Evict unused chunk.Descs in crash recovery	8 years ago
beorn7	08fc6cbd39	storage: Evict unused chunk.Descs in crash recovery This is in line with the v1.5 change in paradigm to not keep chunk.Descs without chunks around after a series maintenance. It's mainly motivated by avoiding excessive amounts of RAM usage during crash recovery. The code avoids to create memory time series with zero chunk.Descs as that is prone to trigger weird effects. (Series maintenance would archive series with zero chunk.Descs, but we cannot do that here because the archive indices still have to be checked.)	8 years ago

Björn Rabenstein	1c6240fc40	Merge pull request #2559 from prometheus/beorn7/storage storage: Replace fpIter by sortedFPs	8 years ago
beorn7	d284ffab03	storage: Replace fpIter by sortedFPs The fpIter was kind of cumbersome to use and required a lock for each iteration (which wasn't even needed for the iteration at startup after loading the checkpoint). The new implementation here has an obvious penalty in memory, but it's only 8 byte per series, so 80MiB for a beefy server with 10M memory time series (which would probably need ~100GiB RAM, so the memory penalty is only 0.1% of the total memory need). The big advantage is that now series maintenance happens in order, which leads to the time between two maintenances of the same series being less random. Ideally, after each maintenance, the next maintenance would tackle the series with the largest number of non-persisted chunks. That would be quite an effort to find out or track, but with the approach here, the next maintenance will tackle the series whose previous maintenance is longest ago, which is a good approximation. While this commit won't change the _average_ number of chunks persisted per maintenance, it will reduce the mean time a given chunk has to wait for its persistence and thus reduce the steady-state number of chunks waiting for persistence. Also, the map iteration in Go is non-deterministic but not truly random. In practice, the iteration appears to be somewhat "bucketed". You can often observe a bunch of series with similar duration since their last maintenance, i.e. you see batches of series with similar number of chunks persisted per maintenance. If that batch is relatively young, a whole lot of series are maintained with very few chunks to persist. (See screenshot in PR for a better explanation.)	8 years ago
