Fabian Reinartz	55a9b5428a	Add separate head mutex ... Introduce a seperate mutex for the head blocks to avoid a race where a post-compaction reload may run between switching the DB's base mutex to create a new head block in an appender.	8 years ago
Fabian Reinartz	ffb24a98f4	Add missing unlock, run debug endpoint in benchmark	8 years ago
Fabian Reinartz	f734773214	Replace per-file locking with single PID lock file ... File locks have a multitude of problems that make them hard to use correctly. As they are just advisory, they are only meaningful to prevent accidents like running the same process twice. A simple PID file lock works reliably in those cases and is simpler.	8 years ago

Fabian Reinartz	9cf49f68e9	wal: use larger buffer	8 years ago
Fabian Reinartz	1c80c33e72	Fix bug of unsorted postings lists being created ... The former approach created unordered postings list by either map iteration of new series being unsorted (fixable) or concurrent writers creating new series interleaved. We switch back to generating ephemeral references for a single batch. Newly created series have to be re-set upon the next insert.	8 years ago

Fabian Reinartz	54f5027406	Put WAL lock down into encoder	8 years ago
Fabian Reinartz	300f4e2abf	Use separate lock for series creation ... This uses the head block's own lock to only lock if new series were encountered. In the general append case we just need to hold a	8 years ago
