Julius Volz 0877680761 Implement a COUNT ... BY aggregation operator. 
This also removes the now obsolete scalar count() function and corrects the
expressions test naming (broken in
2202cd71c9 (L6R59))
so that the expression tests will actually run.

Matt T. Proud 7f548a4297 Merge pull request #228 from prometheus/feature/storage/compaction 
Schedule the background compactors to run.
 2013-05-07 08:50:01 -07:00
Matt Proud 7f0d816574 Schedule the background compactors to run. 
This commit introduces three background compactors, which compact
sparse samples together.

1. Older than five minutes is grouped together into chunks of 50 every 30
   minutes.

2. Older than 60 minutes is grouped together into chunks of 250 every 50
   minutes.

3. Older than one day is grouped together into chunks of 5000 every 70
   minutes.

Make Web Serving Stack's Dependencies Concrete

Matt T. Proud 3b9b1c6ab4 Define dependencies for web. stack concretely. 
This commit destroys the use of AppState, which makes passing
concrete state along to various serving components onerous.

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.

 2013-05-03 03:31:18 -07:00
Bernerd Schaefer 5eb9840ed7 Fix goroutine leak in leveldb.AppendSamples 
The error channels in AppendSamples need to be buffered, since in the
presence of errors their values may not be consumed.

Matt T. Proud 6fac20c8af Harden the tests against OOMs. 
This commit employs explicit memory freeing for the in-memory storage
arenas.  Secondarily, we take advantage of smaller channel buffer sizes
in the test.
