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

Julius Volz	ce1ee444f1	Synchronous memory appends and more fine-grained storage locks. ... This does two things: 1) Make TieredStorage.AppendSamples() write directly to memory instead of buffering to a channel first. This is needed in cases where a rule might immediately need the data generated by a previous rule. 2) Replace the single storage mutex by two new ones: - memoryMutex - needs to be locked at any time that two concurrent goroutines could be accessing (via read or write) the TieredStorage memoryArena. - memoryDeleteMutex - used to prevent any deletion of samples from memoryArena as long as renderView is running and assembling data from it. The LevelDB disk storage does not need to be protected by a mutex when rendering a view since renderView works off a LevelDB snapshot. The rationale against adding memoryMutex directly to the memory storage: taking a mutex does come with a small inherent time cost, and taking it is only required in few places. In fact, no locking is required for the memory storage instance which is part of a view (and not the TieredStorage).	12 years ago
Matt T. Proud	161c8fbf9b	Include deletion processor for long-tail values. ... This commit extracts the model.Values truncation behavior into the actual tiered storage, which uses it and behaves in a peculiar way—notably the retention of previous elements if the chunk were to ever go empty. This is done to enable interpolation between sparse sample values in the evaluation cycle. Nothing necessarily new here—just an extraction. Now, the model.Values TruncateBefore functionality would do what a user would expect without any surprises, which is required for the DeletionProcessor, which may decide to split a large chunk in two if it determines that the chunk contains the cut-off time.	12 years ago

Matt T. Proud	ce45787dbf	Storage interface to TieredStorage. ... This commit drops the Storage interface and just replaces it with a publicized TieredStorage type. Storage had been anticipated to be used as a wrapper for testability but just was not used due to practicality. Merely overengineered. My bad. Anyway, we will eventually instantiate the TieredStorage dependencies in main.go and pass them in for more intelligent lifecycle management. These changes will pave the way for managing the curators without Law of Demeter violations.	12 years ago
