Fabian Reinartz	d951140ab8	wal: avoid heap allocation in WAL reader The buffers we allocated were escaping to the heap, resulting in large memory usage spikes during startup and checkpointing in Prometheus. This attaches the buffer to the reader object to prevent this. Signed-off-by: Fabian Reinartz <freinartz@google.com>	6 years ago
Fabian Reinartz	7841d417b3	Ensure blocks are time-ordered in memory We assume in multiple places that the block list held by DB has blocks sequential by time. A regression caused us to hold them ordered by ULID, i.e. by creation time instead. Signed-off-by: Fabian Reinartz <freinartz@google.com>	6 years ago
Fabian Reinartz	def912ce0e	Integrate new WAL and checkpoints Remove the old WAL and drop in the new one Signed-off-by: Fabian Reinartz <freinartz@google.com>	6 years ago
Fabian Reinartz	008399a6e0	Add checkpointing of WAL segments Create checkpoints from a sequence of WAL segments while filtering out obsolete data. The checkpoint format is again a sequence of WAL segments, which allows us to reuse the serialization format and implementation. Signed-off-by: Fabian Reinartz <freinartz@google.com>	6 years ago
Fabian Reinartz	449a2d0db7	wal: add segment type and repair procedure Allow to repair the WAL based on the error returned by a reader during a full scan over all records. Signed-off-by: Fabian Reinartz <freinartz@google.com>	6 years ago
Fabian Reinartz	8e1f97fad4	wal: add write ahead log package This adds a new WAL that's agnostic to the actual record contents. It's much simpler and should be more resilient than the existing one. Signed-off-by: Fabian Reinartz <freinartz@google.com>	6 years ago

Fabian Reinartz	77db94c07e	Merge pull request #348 from BenoitKnecht/fix-block-boundaries Make sure blocks don't overlap to avoid outsider chunks	6 years ago
Benoît Knecht	24b223c161	db: add test for Querier returning too many blocks Due to the way blocks used to overlap by 1 millisecond (see #347), when requesting a 2-hour interval starting at `blocks[1].MinTime`, the `Querier` would consider three blocks: `blocks[0]`, `blocks[1]` and `blocks[2]`, because `blocks[0].MaxTime` and `blocks[2].MinTime` were in that interval. However, if the blocks don't overlap, only two blocks should be returned: `blocks[1]` and `blocks[2]`. This test ensures that it's indeed the case. Signed-off-by: Benoît Knecht <benoit.knecht@fsfe.org>	6 years ago
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.

Benoît Knecht	4ed6b9ed72	db: add test for chunks that span beyond a block's boundaries Signed-off-by: Benoît Knecht <benoit.knecht@fsfe.org>	6 years ago
Benoît Knecht	0e4be5226a	db: block MaxTime should not be part of the block Block intervals are bound by `block.MinTime`, `block.MaxTime`, but they define a half-open interval: `[block.MinTime, block.MaxTime). However, when deciding if a chunk was part of a block or not, the `intervalOverlap()` function would consider both the chunk and the block intervals as being closed. Rather than modify the login in `intervalOverlap()`, we explicitly remove the last value from the interval when reading from head to persist blocks.
