Fabian Reinartz 3901b6e70b Remove multiple heads
This changes the structure to a single WAL backed by a single head
block.
Parts of the head block can be compacted. This relieves us from any head
amangement and greatly simplifies any consistency and isolation concerns
by just having a single head.

Don't do blocking disk I/O under mutex blocking scrape and eval

Alin Sinpalean 8f7934d025 Take the fdatasync() syscall out from under mutex lock to (mostly) avoid scrape and eval from blocking on disk I/O. 2017-09-01 09:45:54 +02:00
Fabian Reinartz 215a856f34 Just check for general error in WAL test
Go 1.9 changed the returned error. Checking the exact message is too
fragile.

Fabian Reinartz 96d7f540d4 Persist series without allocating the full set
Change index persistence for series to not be accumulated in memory
before being written as one large batch. `Labels` and `ChunkMeta`
objects are reused.
This cuts down memory spikes during compaction of multiple blocks
significantly.

As part of the the Index{Reader,Writer} now have an explicit notion of
symbols and series must be inserted in order.

Fabian Reinartz 9c4235532e Fix compaction selection after creating new heads
This fixes the case where between block creations no compaction
plans are ran. We were not compacting anything in these
cases since the on creation the most recent head block always had
a high timestamp of 0.

Goutham Veeramachaneni f1ae239c20 Persist the right MaxTime when snapshotting
This is because we cut a new block from where the snapshotted block ends
if we restore from backups and highTimestamp would be where we should be
 starting from.

Fabian Reinartz 3410559c1b Compact head block early
Let older head blocks be compacted once the newest once has samples at
50% of its total range. This allows the memory of the compacted blocks
to be released and garbage collected before a new head block gets
created. Thereby the number of head blocks is 1 or 2 instead of 2 or 3
and memory spikes are reduced.
