Matt T. Proud	1ceb25b701	Publication of LevelDBMetricPersistence Fields. This will enable us to break down the onerous construction method. Change-Id: Ia89337ba39d6745af6757180af2485ec8a990a3b	11 years ago
Julius Volz	0003027dce	Add needed trailing spaces in logs.	11 years ago
Julius Volz	aa5d251f8d	Use github.com/golang/glog for all logging.	11 years ago
Matt T. Proud	a5141e4d0a	Depointerize storage conf. and chain ingester. The storage builders need to work with the assumption that they have a copy of the underlying configuration data if any mutations are made.	11 years ago
Matt T. Proud	820e551988	Code Review: Nits.	11 years ago
Matt T. Proud	a3bf2efdd5	Replace index writes with wrapped interface. This commit is the first of several and should not be regarded as the desired end state for these cleanups. What this one does it, however, is wrap the query index writing behind an interface type that can be injected into the storage stack and have its lifecycle managed separately as needed. It also would mean we can swap out underlying implementations to support remote indexing, buffering, no-op indexing very easily. In the future, most of the individual index interface members in the tiered storage will go away in favor of agents that can query and resolve what they need from the datastore without the user knowing how and why they work.	11 years ago
Matt T. Proud	52664f701a	Hot Fix: Use extracted time.	11 years ago
Matt T. Proud	38dac35b3e	Code Review: Short name consistency.	11 years ago
Matt T. Proud	a00f18d78b	Code Review: Manual re-alignment.	11 years ago
Matt T. Proud	cc989c68e1	Replace direct curation table access with wrapper.	11 years ago
Matt T. Proud	07ac921aec	Code Review: First pass.	11 years ago
Matt T. Proud	d8792cfd86	Extract HighWatermarking. Clean up the rest.	11 years ago
Matt T. Proud	f4669a812c	Extract index storage into separate types.	11 years ago
Matt T. Proud	772d3d6b11	Consolidate LevelDB storage construction. There are too many parameters to constructing a LevelDB storage instance for a construction method, so I've opted to take an idiomatic approach of embedding them in a struct for easier mediation and versioning.	11 years ago
Julius Volz	e3415e953f	Add notifications telemetry.	11 years ago
Julius Volz	5d88e8cc45	Round time to nearest second in memory storage. When samples get flushed to disk, they lose sub-second precision anyways. By already dropping sub-second precision, data fetched from memory vs. disk will behave the same. Later, we should consider also storing a more compact representation than time.Time in memory if we're not going to use its full precision.	12 years ago
Matt T. Proud	f7704af4f8	Code Review: Formatting comments.	12 years ago
Julius Volz	a76a797f3f	Always treat series without watermarks as too old. Current series always get watermarks written out upon append now. This drops support for old series without any watermarks by always reporting them as too old (stale) during queries.	12 years ago
Julius Volz	d2da21121c	Implement getValueRangeAtIntervalOp for faster range queries. This also short-circuits optimize() for now, since it is complex to implement for the new operator, and ops generated by the query layer already fulfill the needed invariants. We should still investigate later whether to completely delete operator optimization code or extend it to support getValueRangeAtIntervalOp operators.	12 years ago
Julius Volz	e7f049c85b	Fix expunging of empty memory series (loop var pointerization bug)	12 years ago
Julius Volz	baa5b07829	Fix condition for dropping empty memory series.	12 years ago
Matt T. Proud	30b1cf80b5	WIP - Snapshot of Moving to Client Model.	12 years ago
Matt T. Proud	b811ccc161	Disable paranoid checks and expose max FDs option. We shouldn't need paranoid checks now. We also shouldn't need too many FDs being open due to rule evaluator hitting in-memory values stream.	12 years ago
Matt T. Proud	4137c75523	Shrink default LRU cache sizes. Observing Prometheus in production confirms we can lower these values safely.	12 years ago
Matt T. Proud	ecb9c7bb9d	Code Review: Swap ordering of elements.	12 years ago
Matt T. Proud	5daa0a09ea	Code Review: Swap ordering of watermark getting. A test for Julius.	12 years ago
Matt T. Proud	ee840904d2	Code Review: !Before -> After.	12 years ago
Matt T. Proud	2d5de99fbf	Regard in-memory series as new. This commit ensures that series that exist only in-memory and not on-disk are not regarded as too old for operation exclusion.	12 years ago
Matt T. Proud	a1a23fbaf8	Ensure new metrics are watermarked early. With the checking of fingerprint freshness to cull stale metrics from queries, we should write watermarks early to aid in more accurate responses.	12 years ago
Julius Volz	ba8c122147	Log correct sample count when appending to disk.	12 years ago
Julius Volz	f2b4067b7b	Speedup and clean up operation optimization.	12 years ago
Julius Volz	008bc09da8	Move check for empty memory series to separate method.	12 years ago
Julius Volz	16364eda37	Drop empty series from memory after flushing.	12 years ago
Julius Volz	71199e2c93	Cache disk fingerprint->metric lookups in memory.	12 years ago
Matt T. Proud	a73f061d3c	Persist solely Protocol Buffers. An design question was open for me in the beginning was whether to serialize other types to disk, but Protocol Buffers quickly won out, which allows us to drop support for other types. This is a good start to cleaning up a lot of cruft in the storage stack and can let us eventually decouple the various moving parts into separate subsystems for easier reasoning. This commit is not strictly required, but it is a start to making the rest a lot more enjoyable to interact with.	12 years ago
Julius Volz	558281890b	Minor "go tool vet" cleanups	12 years ago
Matt T. Proud	86f63b078b	Fix fallthrough compaction value ordering. We discovered a regression whereby data chunks could be appended out of order if the fallthrough case was hit.	12 years ago
Julius Volz	7b9ee95030	Minor LevelDB watermark handling cleanups.	12 years ago
Julius Volz	84741b227d	Use LRU cache to avoid querying stale series.	12 years ago
Julius Volz	f98853d7b7	Fix type error in watermark list handling.	12 years ago
Matt T. Proud	ef1d5fd8a2	Introduce semaphores for tiered storage. This commit wraps the tiered storage access componnets in semaphores, since we can handle several concurrent memory reads.	12 years ago
Matt T. Proud	819045541e	Code Review: Make double-drain a panic.	12 years ago
Matt T. Proud	e217a9fb41	Race Work: Make memory arena locks more coarse. We can optimize these as needed later.	12 years ago
Matt T. Proud	beaaf386e7	Add storage state guards and transition callbacks. To ensure that we access tiered storage in the proper way, we have guards now.	12 years ago
Matt T. Proud	2c3df44af6	Ensure database access waits until it is started. This commit introduces a channel message to ensure serving state has been reached with the storage stack before anything attempts to use it.	12 years ago
Matt T. Proud	cbe2f3a7b1	Include LRU cache for fingerprint watermarks.	12 years ago
Julius Volz	51689d965d	Add debug timers to instant and range queries. This adds timers around several query-relevant code blocks. For now, the query timer stats are only logged for queries initiated through the UI. In other cases (rule evaluations), the stats are simply thrown away. My hope is that this helps us understand where queries spend time, especially in cases where they sometimes hang for unusual amounts of time.	12 years ago
Matt T. Proud	8339a189cb	Code Review: Fix seriesPresent scope. The seriesPresent scope should be constrained to the scope of a scanJob, since this is keyed to given series.	12 years ago
Matt T. Proud	fe41ce0b19	Conditionalize disk initializations. This commit conditionalizes the creation of the diskFrontier and seriesFrontier along with the iterator such that they are provisioned once something is actually required from disk.	12 years ago
Julius Volz	a8468a2e5e	Fix reversed disk flush cutoff behavior.	12 years ago
