juliusv	92ad65ff13	Merge pull request #232 from prometheus/optimize/granular-storage-locking ... Synchronous memory appends and more fine-grained storage locks.	12 years ago
Matt T. Proud	dad20c15e7	Merge pull request #243 from prometheus/feature/size-exposition ... Simplify compaction and expose database sizes.	12 years ago
Matt T. Proud	1f7f89b4e3	Simplify compaction and expose database sizes. ... This commit simplifies the way that compactions across a database's keyspace occur due to reading the LevelDB internals. Secondarily it introduces the database size estimation mechanisms.	12 years ago
Matt T. Proud	5b183f6434	Merge pull request #242 from prometheus/feature/storage/long-tail-deletion ... Include long-tail data deletion mechanism.	12 years ago
Matt T. Proud	d538b0382f	Include long-tail data deletion mechanism. ... This commit introduces the long-tail deletion mechanism, which will automatically cull old sample values. It is an acceptable hold-over until we get a resampling pipeline implemented. Kill legacy OS X documentation, too.	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	fa6a1f97d0	Expose interfaces for pruner and make pruner tool. ... In order to run database cleanups and diagnostics, we should have a means for pruning a database---even if LevelDB does this for us.	12 years ago
juliusv	76521c3ff0	Merge pull request #234 from prometheus/feature/storage/long-tail-deletion ... Include deletion processor for long-tail values.	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

juliusv	0dc15d28cb	Merge pull request #233 from prometheus/feature/count-by ... Implement a COUNT ... BY aggregation operator.	12 years ago
Matt T. Proud	38d839d810	Include generated Protocol Buffers artifacts. ... This commit reduces the general compile time dependencies to omit the Protocol Buffer compiler and the Go Protocol Buffer generator tool. The build steps to furnish them still remain, but they can optionally be called if data.proto or config.proto are under work.	12 years ago
Julius Volz	0877680761	Implement a COUNT ... BY aggregation operator. ... This also removes the now obsolete scalar count() function and corrects the expressions test naming (broken in 2202cd71c9 (L6R59)) so that the expression tests will actually run.	12 years ago

Matt T. Proud	7f548a4297	Merge pull request #228 from prometheus/feature/storage/compaction ... Schedule the background compactors to run.	12 years ago
Matt Proud	7f0d816574	Schedule the background compactors to run. ... This commit introduces three background compactors, which compact sparse samples together. 1. Older than five minutes is grouped together into chunks of 50 every 30 minutes. 2. Older than 60 minutes is grouped together into chunks of 250 every 50 minutes. 3. Older than one day is grouped together into chunks of 5000 every 70 minutes.	12 years ago

Matt T. Proud	3b9b1c6ab4	Define dependencies for web. stack concretely. ... This commit destroys the use of AppState, which makes passing concrete state along to various serving components onerous.	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

Bernerd Schaefer	5eb9840ed7	Fix goroutine leak in leveldb.AppendSamples ... The error channels in AppendSamples need to be buffered, since in the presence of errors their values may not be consumed.	12 years ago
