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 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.

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.

Fabian Reinartz 4962175218 Fix deadlock between heads and headmtx
With hundreds of concurrent appenders the locking order between the
headBlocks on instantiating appenders and write locking the headmtx
is hard to impossible to get consistent.
Just never instantiate appenders while holding the headmtx lock in any
way.

This fixes a bug where the last WAL file was closed after consuming it
instead of being left open for further writes.
