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.

Matt T. Proud b3e34c6658 Implement batch database sample curator.
This commit introduces to Prometheus a batch database sample curator,
which corroborates the high watermarks for sample series against the
curation watermark table to see whether a curator of a given type
needs to be run.

The curator is an abstract executor, which runs various curation
strategies across the database.  It remarks the progress for each
type of curation processor that runs for a given sample series.

A curation procesor is responsible for effectuating the underlying
batch changes that are request.  In this commit, we introduce the
CompactionProcessor, which takes several bits of runtime metadata and
combine sparse sample entries in the database together to form larger
groups.  For instance, for a given series it would be possible to
have the curator effectuate the following grouping:

- Samples Older than Two Weeks: Grouped into Bunches of 10000
- Samples Older than One Week: Grouped into Bunches of 1000
- Samples Older than One Day: Grouped into Bunches of 100
- Samples Older than One Hour: Grouped into Bunches of 10

The benefits hereof of such a compaction are 1. a smaller search
space in the database keyspace, 2. better employment of compression
for repetious values, and 3. reduced seek times.

Julius Volz 99dcbe0f94 Integrate memory and disk layers in view rendering. 2013-04-19 16:01:27 +02:00
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.
