Fabian Reinartz 25d4546518 Merge pull request #42 from prometheus/amend-nan 
When checking for amended points, do it in terms of bits.
 2017-04-13 08:53:02 +02:00
Brian Brazil bceb5c1b16 When checking for amended points, do it in terms of bits. 
NaN != NaN, so the previous code would incorrectly report
it as changed.

There's also plans to take advantage of the NaN payload,
so look at the entire value.

Fabian Reinartz 767b88a3a5 Parallelize commits to prevent deadlocks 
This parallelizes commits to prevent deadlocks across inconsistently
locked heads. As commits are currently not fully atomic across
heads, this does decrease our guarantees.

Fabian Reinartz 87d48bf9de Merge branch 'master' of github.com:fabxc/tsdb 2017-03-27 19:07:27 +02:00
Fabian Reinartz a52980e0a8 Add workaround for deadlocks 
This adds a workaround to avoid deadlocks for inconsistent write lock
order across headBlocks.
Things keep working if transactions only append data for the same
timestamp, which is generally the case for Prometheus.

Full behavior should be restored in a subsequent change.

Rename bytePostings To bigEndianPostings 
* To be more specific about the contents of the byte slice.

Implement Postings Iterator Over Bytes 
Closes fabxc/tsdb#18

Goutham Veeramachaneni 61f866bb94
Add Sample Back 
The compilation and tests are broken as head.go requires sample which
has been moved to another package while moving BufferedSeriesIterator.

Duplication seemed better compared to exposing sample from tsdbutil.

Fabian Reinartz 3be4ef94ce Move BufferedSeriesIterator in own package 
This functionality is useful for a lot of clients but not relevant to
the TSDB's core features.

Fabian Reinartz e478d0e3bc Actually close olds blocks in reloadBlocks 
This fixes a bug leaking memory because blocks were not actually closed
as the closing call references the initial, empty slice
 2017-03-23 18:27:20 +01:00
Fabian Reinartz 70909ca8ad Ensure GC runs after each compactor call 
GC is triggered rarely, which may cause unnecessarily high memory
spikes when running several compaction cycles in a row. Explicitly run
GC so we don't have idle bytes marked as used from the previous cycle.

Fabian Reinartz 9c93f8f2aa Fix various races 
This fixes different race condition encoutnered when running Prometheus.
It reduces the overall performance in the synthetic benchmark a fair bit
but has no indiciations of impacting a real-world setup notably.

Fabian Reinartz 2c999836fb Add Queryable interface to Block 
This adds the Queryable interface to the Block interface. Head and
persisted blocks now implement their own Querier() method and thus
isolate customization (e.g. remapPostings) more cleanly.
 2017-03-20 10:21:21 +01:00
Fabian Reinartz 11be2cc585 Add composed Block interfaces, remove head generation 
This adds more lower-leve interfaces which are used to compose
to different Block interfaces.
The DB only uses interfaces instead of explicit persistedBlock and
headBlock. The headBlock generation property is dropped as the use-case
can be implemented using block sequence numbers.
