beorn7	47e3c90f9b	Clean up error propagation Only return an error where callers are doing something with it except simply logging and ignoring. All the errors touched in this commit flag the storage as dirty anyway, and that fact is logged anyway. So most of what is being removed here is just log spam. As discussed earlier, the class of errors that flags the storage as dirty signals fundamental corruption, no even bubbling up a one-time warning to the user (e.g. about incomplete results) isn't helping much because _anything_ happening in the storage has to be doubted from that point on (and in fact retroactively into the past, too). Flagging the storage dirty, and alerting on it (plus marking the state in the web UI) is the only way I can see right now. As a byproduct, I cleaned up the setDirty method a bit and improved the logged errors.	9 years ago

beorn7	836f1db04c	Improve MetricsForLabelMatchers WIP: This needs more tests. It now gets a from and through value, which it may opportunistically use to optimize the retrieval. With possible future range indices, this could be used in a very efficient way. This change merely applies some easy checks, which should nevertheless solve the use case of heavy rule evaluations on servers with a lot of series churn. Idea is the following: - Only archive series that are at least as old as the headChunkTimeout (which was already extremely unlikely to happen). - Then maintain a high watermark for the last archival, i.e. no archived series has a sample more recent than that watermark. - Any query that doesn't reach to a time before that watermark doesn't have to touch the archive index at all. (A production server at Soundcloud with the aforementioned series churn and heavy rule evaluations spends 50% of its CPU time in archive index lookups. Since rule evaluations usually only touch very recent values, most of those lookup should disappear with this change.) - Federation with a very broad label matcher will profit from this, too. As a byproduct, the un-needed MetricForFingerprint method was removed from the Storage interface.	9 years ago

Fabian Reinartz	56fc9bdff3	Handle closed target provider channel This fixes the case where a target provider closes the update channel and exits before the context is canceled. This should only be true for the static provider but it's safer to generally handle this case.	9 years ago

beorn7	c13b1ecfe9	Make chunk iterators more DRY This finally extracts all the common code of the two chunk iterators into one. Any future chunk encodings with fast access by index can use the same iterator by simply providing an indexAccessor. Other future chunk encodings without fast index access (like Gorilla-style) can still implement the chunkIterator interface as usual.	9 years ago
beorn7	32f280a3cd	Slim down the chunkIterator interface For one, remove unneeded methods. Then, instead of using a channel for all values, use a bufio.Scanner-like interface. This removes the need for creating a goroutine and avoids the (unnecessary) locking performed by channel sending and receiving. This will make it much easier to write new chunk implementations (like Gorilla-style encoding).	9 years ago

beorn7	f193f2b8ef	Add a command to promtool that dumps metadata of heads.db I needed this today for debugging. It can certainly be improved, but it's already quite helpful. I refactored the reading of heads.db files out of persistence, which is an improvement, too. I made minor changes to the cli package to allow outputting via the io.Writer interface.	9 years ago
