Benoît Knecht	1e1b2e163d	Make interval overlap comparisons more explicit ... Blocks are half-open intervals [a, b), while all other intervals (chunks, head, ...) are closed intervals [a, b]. Make that distinction explicit by defining `OverlapsClosedInterval()` methods for blocks and chunks, and using them in place of the more generic `intervalOverlap()` function. This change also fixes `db.Querier()` and `db.Delete()`, which could previously return one extraneous block at the end of the specified interval.

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	5d75a3dc7b	Add basic compaction ... This adds a basic compactor that will merge two persisted blocks into one. It simply fully rewrites the index and concatenates the chunk lists. It just writes into the current working dir and doesn't properly handle which blocks to compact for now.	10 years ago

Fabian Reinartz	8c48dc2ca5	chunks: varint encoding in first full 64bit numbers ... This saves about 7 bytes per chunk	10 years ago
Fabian Reinartz	5e76fd3126	chunks: drop shift, remove branch ... This removes the need for the shift value and just calculates everything on the fly through count. Removes a branch condition.	10 years ago
Fabian Reinartz	c9ee572709	chunks: don't mutate in bstream iterator ... This replaces mutation of underlying bytes in the iterated slice with a shift counter, which is used when reading the head byte. This is avoids having to copy the entire slice for every new iterator.	10 years ago

Fabian Reinartz	fa181a34c1	chunks: cleanup anything but xor encoding ... xor encoding is fast enough for our purposes and provides very good compression. We remove all other ones that partially don't support floats for the sake of simplicity.	10 years ago
