Fabian Reinartz	3ef4326114	Refactor tombstone reader types	8 years ago
Fabian Reinartz	e5ce2bef43	Add explicit error to Querier.Select ... This has been a frequent source of debugging pain since errors are potentially delayed to a much later point. They bubble up in an unrelated execution path.	8 years ago
Fabian Reinartz	d578b10d5c	chunk: make reader accept abstract ByteSlice	8 years ago
Fabian Reinartz	b7c3cfecbf	index: abstract ByteSlice and adjust indexReader ... This replaces the builtin byte slice with an interface for the index reader. This allows the complex decoding of the index file format to be used against more generalized implementations.	8 years ago
Sunny Klair	4fdf9b195c	Validate index TOC checksum on read	8 years ago
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	78df406dac	Allocate and cache strings for persisted blocks ... This change loads the full symbol table when we open a persisted block and allocates a string for each. This ensures that strings retrieved through the index can be used after the block was closed. Before we backed the strings by the mmap'd byte regions which would segfault in this case. Also remove an inconsistency in the disk format and move both offset tables to the end (breaking change).	8 years ago

Fabian Reinartz	5cf2662074	Refactor WAL into Head and misc improvements	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
Goutham Veeramachaneni	7438ed7035	Expose Intervals type for use by TombstoneReader. ... TombstoneReader is exposed but Intervals is not. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago

Fabian Reinartz	2644c8665c	Don't allocate ChunkMetas, reuse postings slices	9 years ago
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.	9 years ago
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.	9 years ago
