Goutham Veeramachaneni	c35d3a65bd	Add levels to all log lines. ... Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	7 years ago
Fabian Reinartz	1e88ba06b4	Use boolean function instead of postings to drop WAL series ... There is not guarantee or requirement for WAL writers to only add series entries in increasing order of IDs. A postings list cannot look back and thus unordered WAL entries would skip over IDs to not truncate from the WAL. We replace it with a simple boolean check function that does not require order.	7 years ago

Fabian Reinartz	7ada9cd805	Simplify series create logic in head	7 years ago
Fabian Reinartz	6892fc6dcb	Finish old WAL segment async, default to no fsync ... We were still fsyncing while holding the write lock when we cut a new segment. Given we cannot do anything but logging errors, we might just as well complete segments asynchronously. There's not realistic use case where one would fsync after every WAL entry, thus make the default of a flush interval of 0 to never fsync which is a much more likely use case.	7 years ago

Fabian Reinartz	33e9bdf403	WAL refactoring and truncation fixes and test	7 years ago
Fabian Reinartz	c36d574290	Replace single head lock with granular locks ... This adds various new locks to replace the single big lock on the head. All parts now must be COW as they may be held by clients after initial retrieval. Series by ID and hashes are now held in a stripe lock to reduce contention and total holding time during GC. This should reduce starvation of readers.	7 years ago

Fabian Reinartz	5cf2662074	Refactor WAL into Head and misc improvements	7 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.	7 years ago
Alin Sinpalean	8f7934d025	Take the fdatasync() syscall out from under mutex lock to (mostly) avoid scrape and eval from blocking on disk I/O.	7 years ago
