Matt T. Proud b00ca7e422 Refactor some greediness computations. 2013-03-21 18:08:48 +01:00
Matt T. Proud 978acd4e96 Simplify time group optimizations. 
The old code performed well according to the benchmarks, but the
new code shaves 1/6th of the time off the original and with less
code.

Matt T. Proud 62b5d7ce20 Oops. 2013-03-21 18:08:46 +01:00
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 13ae29b304 Initial in-memory arena implementation. 
It is unbounded, and nothing uses it except for a gating flag in main.

Julius Volz 2659304380 Add interface for getting all metrics from a MetricsPersistence. 2013-02-06 17:06:39 +01:00
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
re-exposes this through flags.  We can now perform benchmarking
and remedial tuning.

Matt T. Proud ea54751431 Update import paths to new location. 
This repository moved from matttproud/prometheus to
prometheus/prometheus, and all import paths need to be updated.
 2013-01-27 18:49:45 +01:00
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.

Julius Volz 6f937ee032 Add preliminary metric docstrings and empty base labels. 2013-01-18 01:37:50 +01:00
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.
