Goutham Veeramachaneni	ce23adb579	Initial compaction implementation for block-ranges ... Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	9 years ago
Fabian Reinartz	1e74c155eb	Return empty string to signal non-caching	9 years ago
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.	9 years ago

Brian Brazil	dba222b53c	Make rollback actually rollback. ... Also add tests for basic commit/rollback functionality. Fixes #39	9 years ago
Matt Bostock	4d5ca4b9c1	db: Fix typo: reference	9 years ago
Matt Bostock	3dd5a4ee09	db: Add comment: Appender not goroutine safe	9 years ago
Fabian Reinartz	778103b450	Add liecence file and headers	9 years ago
Fabian Reinartz	10c7c9acbe	Adjust import names to new repository organisation	9 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.	9 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.	9 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	9 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.	9 years ago
Fabian Reinartz	c18e055d7c	Fix races and add comments on remaining ones	9 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.	9 years ago
Fabian Reinartz	3635569257	Trigger reload correctly on interrupted compaction	9 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.	9 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.	9 years ago
Goutham Veeramachaneni	df7db4ac07	Update kit/log To New API ... NewContext has been removed couple of weeks back. Ref: https://github.com/go-kit/kit/releases/tag/v0.4.0	9 years ago

Fabian Reinartz	863d38dfee	Fix unreturned lock	9 years ago
Fabian Reinartz	d0770302ed	Add retention deletion	9 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. Just never instantiate appenders while holding the headmtx lock in any way.	9 years ago
Fabian Reinartz	65b846ae5b	Remove unreturned locks, detect writes on closed heads	9 years ago
Fabian Reinartz	32c32013a6	Fix loading of persisted blocks	9 years ago
Fabian Reinartz	cb4dde7659	Fix WAL log recovery bug ... This fixes a bug where the last WAL file was closed after consuming it instead of being left open for further writes. Reloading of blocks on startup considers loading head blocks now.	9 years ago

Fabian Reinartz	87805fb83f	Remove Partitioned* code	9 years ago
