Julius Volz 2668700e54 Fix bug in GetFingerprintsForLabelSet(). 2013-03-27 18:50:30 +01:00
Matt T. Proud c53a72a894 Test data for the curator. 2013-03-27 18:13:43 +01:00
Matt T. Proud 6dcaa28806 Include LevelDB fixture generators for curator. 
This will help reduce common boilerplate for our test process
with respect to LevelDB-related things.

Julius Volz 991dc68d78 Rename misnamed oldestSampleTimestamp variable. 2013-03-26 11:56:10 +01:00
Matt T. Proud 3e97a3630d Include nascent curator scaffolding. 
The curator doesn't do anything yet; rather, this is the type
definition including the anciliary testing scaffold.

Improve Makefile and Git developer experience.

The top-level Makefile was a bit overloaded in terms of generation of
assets and their management.  This has been offloaded into separate
Makefiles.

The Git developer experience sucked due to lack of .gitignore
policies.

Also: Fix faulty skiplist naming from old merge.
 2013-03-25 19:38:14 +01:00
Matt T. Proud b2e4c88b80 Wrap LevelDB iterator operations behind interface. 
The LevelDB storage types return an interface type now that wraps
around the underlying iterator.  This both enhances testability but
improves upon, in my opinion, the interface design for the LevelDB
iterator.

Secondarily, the resource reaping behaviors for the LevelDB iterators
have been improved by dropping the externalized io.Closer object.

Finally, the iterator provisioning methods provide the option for
indicating whether one wants a snapshotted iterator or not.
 2013-03-25 12:57:58 +01:00
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.
 2013-03-25 08:38:21 +01:00

 - Extract batching behavior into interface.
 - Kill IteratorManager, which was used for unknown reasons.

behavior.

Matt T. Proud 1e0d740f2a Conditionalize LevelDB index retrievals. 
The LevelDB index retrievals could be repeated in a given operation
batch if multiple queued mutations affect the same (Label Name) singles
and (Label Name, Label Value) doubles.  This is wasteful and
inefficient, as a single retrieval suffices.  Thusly this commit
retrieves the canonical index mappings if the said mapping has not
been looked up in a given batch.

Matt T. Proud ec3e98b365 Include Snappy in Runtime. 
Snappy should have been explicitly included in the runtime, for I
erroneously thought that LevelDB bundled this into its runtime as-is.
It turns out that this assumption is wrong, and I thought we had
Snappy compression support all-along.

Matt T. Proud 79ba248bbe Make LevelDB operating modes invocation-time conf. 
Presently our use of LevelDB and its operating modes are hardcoded
into the storage stack.  This pull request decouples this and

and remedial tuning.

Matt T. Proud f2ded515b7 Support versioned telemetry providers. 
client_golang was updated to support full label-oriented telemetry,
which introduced interface incompatibilities with the previous
version of Prometheus.  To alleviate this, a general fetching and
processing dispatching system has been created, which discriminates
and processes according to the version of input.

Matt T. Proud d9b165220e ``GetFingerprintsForLabelSet`` uses intersection. 
This implementation needs to be cleaned up considerably, but it
should hopefully provide some breathing room.  Ultimately this will
be extracted out of the storage layer---specifically the LevelDB
hierarchy---to interface with a generic set of abstractions for a
storage system, but this will be where it remains for now.
