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>	8 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>	8 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>	8 years ago
