Fabian Reinartz	fb9da52b11	Add more verbose error handling for closing, reduce locking ... This commit introduces error returns in various places and is explicit about closing persisted blocks. {Index,Chunk,Tombstone}Readers are more consistent about their Close() method. Whenever a reader is retrieved, the corresponding close method must eventually be called. We use this to track pending readers against persisted blocks. Querier's against the DB no longer hold a read lock for their entire lifecycle. This avoids long running queriers to starve new ones when we have to acquire a write lock when reloading blocks.	8 years ago

Fabian Reinartz	c36d574290	Replace single head lock with granular locks ... This adds various new locks to replace the single big lock on the head. All parts now must be COW as they may be held by clients after initial retrieval. Series by ID and hashes are now held in a stripe lock to reduce contention and total holding time during GC. This should reduce starvation of readers.	8 years ago

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.	8 years ago
