Julius Volz	1eee448bc1	Store samples in custom binary encoding. ... This has been shown to provide immense decoding speed benefits. See also: https://groups.google.com/forum/#!topic/prometheus-developers/FeGl_qzGrYs Change-Id: I7d45b4650e44ddecaa91dad9d7fdb3cd0b9f15fe	12 years ago
Bjoern Rabenstein	6bc083f38b	Major code cleanup in storage. ... - Mostly docstring fixed/additions. (Please review these carefully, since most of them were missing, I had to guess them from an outsider's perspective. (Which on the other hand proves how desperately required many of these docstrings are.)) - Removed all uses of new(...) to meet our own style guide (draft). - Fixed all other 'go vet' and 'golint' issues (except those that are not fixable (i.e. caused by bugs in or by design of 'go vet' and 'golint')). - Some trivial refactorings, like reorder functions, minor renames, ... - Some slightly less trivial refactoring, mostly to reduce code duplication by embedding types instead of writing many explicit forwarders. - Cleaned up the interface structure a bit. (Most significant probably the removal of the View-like methods from MetricPersistenc. Now they are only in View and not duplicated anymore.) - Removed dead code. (Probably not all of it, but it's a first step...) - Fixed a leftover in storage/metric/end_to_end_test.go (that made some parts of the code never execute (incidentally, those parts were broken (and I fixed them, too))).

Matt T. Proud	4a87c002e8	Update low-level i'faces to reflect wireformats. ... This commit fixes a critique of the old storage API design, whereby the input parameters were always as raw bytes and never Protocol Buffer messages that encapsulated the data, meaning every place a read or mutation was conducted needed to manually perform said translations on its own. This is taxing. Change-Id: I4786938d0d207cefb7782bd2bd96a517eead186f	13 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.	13 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.	13 years ago
Matt T. Proud	f2a30cf20c	Several important cleanups and deprecations. ... EachFunc is deprecated. Remove deprecated ``Pair`` and ``GetAll``. These were originally used for forensic and the old gorest impl. Nothing today in the user-facing path nor the tests uses them, especially since the advent of the ForEach protocol in the interface.	13 years ago
