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	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	4b30fb86b4	Revert "Ensure that all extracted samples are added to view." This reverts commit `008314b5a8`. By running an automated git bisection described in https://gist.github.com/matttproud-soundcloud/22a371a8d2cba382ea64 this commit was found.	12 years ago

Julius Volz	008314b5a8	Ensure that all extracted samples are added to view. The current behavior only adds those samples to the view that are extracted by the last pass of the last processed op and throws other ones away. This is a bug. We need to append all samples that are extracted by each op pass. This also makes view.appendSamples() take an array of samples.	12 years ago

Matt T. Proud	e5ac91222b	Benchmark memory arena; simplify map generation. The one-off keys have been replaced with ``model.LabelPair``, which is indexable. The performance impact is negligible, but it represents a cognitive simplification.	12 years ago

Julius Volz	83c60ad43a	Fix GetMetricForFingerprint() metric mutability. Some users of GetMetricForFingerprint() end up modifying the returned metric labelset. Since the memory storage's implementation of GetMetricForFingerprint() returned a pointer to the metric (and maps are reference types anyways), the external mutation propagated back into the memory storage. The fix is to make a copy of the metric before returning it.	12 years ago
Julius Volz	99dcbe0f94	Integrate memory and disk layers in view rendering.	12 years ago
Julius Volz	63625bd244	Make view use memory persistence, remove obsolete code. This makes the memory persistence the backing store for views and adjusts the MetricPersistence interface accordingly. It also removes unused Get* method implementations from the LevelDB persistence so they don't need to be adapted to the new interface. In the future, we should rethink these interfaces. All staleness and interpolation handling is now removed from the storage layer and will be handled only by the query layer in the future.	12 years ago
Matt T. Proud	a55602df4a	Validate diskFrontier domain for series candidate. It is the case with the benchmark tool that we thought that we generated multiple series and saved them to the disk as such, when in reality, we overwrote the fields of the outgoing metrics via Go map reference behavior. This was accidental. In the course of diagnosing this, a few errors were found: 1. ``newSeriesFrontier`` should check to see if the candidate fingerprint is within the given domain of the ``diskFrontier``. If not, as the contract in the docstring stipulates, a ``nil`` ``seriesFrontier`` should be emitted. 2. In the interests of aiding debugging, the raw LevelDB ``levigoIterator`` type now includes a helpful forensics ``String()`` method. This work produced additional cleanups: 1. ``Close() error`` with the storage stack is technically incorrect, since nowhere in the bowels of it does an error actually occur. The interface has been simplified to remove this for now.	12 years ago
