Bjoern Rabenstein	fee88a7a77	Remove the remaining races, new and old. ... Also, resolve a few other TODOs. Change-Id: Icb39b5a5e8ca22ebcb48771cd8951c5d9e112691	10 years ago
Bjoern Rabenstein	7d11019aa2	Squash a few trivial TODOs. ... - Delete unneeded file view_adapter.go. - Assessed that we still need the fingerprints in nodes (to create iterators). - Turned numMemChunkDescs into a metric. Change-Id: I29be963c795a075ec00c095f76bf26405535609d	10 years ago

Bjoern Rabenstein	bb42cc2e2d	Evict based on memory pressure. Evict recently used chunks last. ... Change-Id: Ie6168f0cdb3917bdc63b6fe15585dd70c1e42afe	10 years ago
Bjoern Rabenstein	a617269b12	Avoid unnecessary cloning of the head chunk. ... Change-Id: I5da774515d5493166a197b5814d0a720628cfaff	10 years ago
Bjoern Rabenstein	74c9b34a5e	Improve storage instrumentation even more. ... Add gauge for chunks and chunkdescs in memory (backed by a global variable to be used later not only for instrumentation but also for memory management). Refactored instrumentation code once more (instrumentation.go is back :). Change-Id: Ife39947e22a48cac4982db7369c231947f446e17	10 years ago
Bjoern Rabenstein	443dd33805	Improve instrumentation in storage. ... Also, fix some other minor bugs. Change-Id: If72f1c058b0f47d3e378fdf80228d7e9a8db06c7	10 years ago
Bjoern Rabenstein	096fa0f8b2	Squash a number of TODOs. ... - Staleness delta is no a proper function parameter and not replicated from package ast. - Named type 'chunks' replaced by explicit '[]chunk' to avoid confusion. - For the same reason, replaced 'chunkDescs' by '[]*chunkDescs'. - Verified that math.Modf is not a speed enhancement over conversion (actually 5x slower). - Renamed firstTimeField, lastTimeField into chunkFirstTime and chunkLastTime. - Verified unpin() is sufficiently goroutine-safe. - Decided not to update archivedFingerprintToTimeRange upon series truncation and added a rationale why.

Bjoern Rabenstein	d742edfe0d	Fix precision loss. ... Large delta values often imply a difference between a large base value and the large delta value, potentially resulting in small numbers with a huge precision error. Since large delta values need 8 bytes anyway, we are not even saving memory. As a solution, always save the absoluto value rather than a delta once 8 bytes would be needed for the delta. Timestamps are then saved as 8 byte integers, while values are always saved as float64 in that case. Change-Id: I01100d600515e16df58ce508b50982ffd762cc49	10 years ago
