Julius Volz	1dad3370fd	Close WAL when closing the DB Also, the `wal` field of the `DB` was not used anywhere, so this removes it.	7 years ago
Tobias Schmidt	5170198276	Fix typo in prometheus_tsdb_reloads_failures_total description	7 years ago
Fabian Reinartz	d226411a2a	db: delete old blocks during reload Windows requires blocks to be closed before deleting their directories. This adds a set of deleteable blocks to reload(), which then deletes them without causing disruption to querying.	7 years ago
Your Name	4a4a706234	close blocks which will be remove	7 years ago
Fabian Reinartz	d109149d17	Merge pull request #186 from prometheus/closeallblocks Ensure readers are closed on setup failure.	7 years ago
Fabian Reinartz	f8e88bfdb7	Close previous block queriers on error This ensures we close all previously opened queriers if on of the block querier fails to open. Also swap in new blocks before closing old ones to avoid the situation in general. Make read locking of blocks more conservative to avoid unnecessary retries by clients, e.g. when blocks are getting closed before we can successfully instantiate querier against them.	7 years ago
Fabian Reinartz	d17104f1f0	Prefix all metrics with `prometheus_*`	7 years ago
Fabian Reinartz	fb9da52b11	Add more verbose error handling for closing, reduce locking This commit introduces error returns in various places and is explicit about closing persisted blocks. {Index,Chunk,Tombstone}Readers are more consistent about their Close() method. Whenever a reader is retrieved, the corresponding close method must eventually be called. We use this to track pending readers against persisted blocks. Querier's against the DB no longer hold a read lock for their entire lifecycle. This avoids long running queriers to starve new ones when we have to acquire a write lock when reloading blocks.	7 years ago

Fabian Reinartz	81222849bc	Filter WAL data in Head, misc fixes	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	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

Fabian Reinartz	9c4235532e	Fix compaction selection after creating new heads This fixes the case where between block creations no compaction plans are ran. We were not compacting anything in these cases since the on creation the most recent head block always had a high timestamp of 0.	7 years ago

Goutham Veeramachaneni	f1ae239c20	Persist the right MaxTime when snapshotting This is because we cut a new block from where the snapshotted block ends if we restore from backups and highTimestamp would be where we should be starting from.

Fabian Reinartz	3410559c1b	Compact head block early Let older head blocks be compacted once the newest once has samples at 50% of its total range. This allows the memory of the compacted blocks to be released and garbage collected before a new head block gets created. Thereby the number of head blocks is 1 or 2 instead of 2 or 3 and memory spikes are reduced.	8 years ago

Fabian Reinartz	767b88a3a5	Parallelize commits to prevent deadlocks This parallelizes commits to prevent deadlocks across inconsistently locked heads. As commits are currently not fully atomic across heads, this does decrease our guarantees.	8 years ago
Fabian Reinartz	a52980e0a8	Add workaround for deadlocks This adds a workaround to avoid deadlocks for inconsistent write lock order across headBlocks. Things keep working if transactions only append data for the same timestamp, which is generally the case for Prometheus. Full behavior should be restored in a subsequent change.	8 years ago
Fabian Reinartz	e478d0e3bc	Actually close olds blocks in reloadBlocks This fixes a bug leaking memory because blocks were not actually closed as the closing call references the initial, empty slice	8 years ago
Fabian Reinartz	70909ca8ad	Ensure GC runs after each compactor call GC is triggered rarely, which may cause unnecessarily high memory spikes when running several compaction cycles in a row. Explicitly run GC so we don't have idle bytes marked as used from the previous cycle.	8 years ago

Fabian Reinartz	9c93f8f2aa	Fix various races This fixes different race condition encoutnered when running Prometheus. It reduces the overall performance in the synthetic benchmark a fair bit but has no indiciations of impacting a real-world setup notably.	8 years ago
Fabian Reinartz	3635569257	Trigger reload correctly on interrupted compaction	8 years ago
Fabian Reinartz	2c999836fb	Add Queryable interface to Block This adds the Queryable interface to the Block interface. Head and persisted blocks now implement their own Querier() method and thus isolate customization (e.g. remapPostings) more cleanly.	8 years ago
Fabian Reinartz	11be2cc585	Add composed Block interfaces, remove head generation This adds more lower-leve interfaces which are used to compose to different Block interfaces. The DB only uses interfaces instead of explicit persistedBlock and headBlock. The headBlock generation property is dropped as the use-case can be implemented using block sequence numbers.	8 years ago

Fabian Reinartz	4962175218	Fix deadlock between heads and headmtx With hundreds of concurrent appenders the locking order between the headBlocks on instantiating appenders and write locking the headmtx is hard to impossible to get consistent.
