Christian Haudum	f52f8ad540	chore: Clarify compression package (#14257 ) This PR renames "encoding" to "codec" in the compression package to remove the cognitive dissonance. It also removes the `Enc` prefix for codec identifiers, so that they adhere Go's best practice of naming conventions, e.g. `compression.EncGZIP` becomes `compression.GZIP` when used in a different package.

Christian Haudum	963779064b	chore: Move compression utilities into separate package (#14167 ) Compression tooling has been part of the `chunkenc` (chunk encoding) package in the past for legacy reasons. Since more components use this now, it's easier to keep it in a separate package. This also eliminates the confusion around "encoding", since this has been incorrectly used synonymously with "compression" in the past. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com> Co-authored-by: Robert Fratto <robertfratto@gmail.com>	8 months ago

Michel Hollands	8628b15624	Use metrics namespace for more metrics (#11025 ) What this PR does / why we need it: Use the metrics namespace setting instead of hardcoding to `cortex`.

Arve Knudsen	489ca25bab	Upgrade to Prometheus@4b9c19fe5510 (#10843 ) What this PR does / why we need it: Upgrade to Prometheus@4b9c19fe5510. Since also golang.org/x/exp gets upgraded, calls to e.g. `slices.SortFunc` need updating (due to changed comparison function signature). I'm not aware of any functional changes from Prometheus (or otherwise), but please review carefully. Special notes for your reviewer: The Mimir team needs for Loki to be compatible with the latest Prometheus, so we can vendor mimir-prometheus@main into GEM.

Christian Haudum	31981bd4af	Remove dependency on Bigchunk, which is a leftover of Cortex and is only used in tests (#10354 ) What this PR does / why we need it: This PR removes the dependency on "Bigchunk", which is a "default" implementation of the `chunk.Data` interface and used only in tests. Special notes for your reviewer: The PR replaces the usage of this chunk type with the Loki implementation (`chunkenc.MemChunk` wrapped into `chunkenc.Facade`) where possible. In case where it was not possible (tests in `pkg/storage/chunk` package) due to otherwise circular import, it was replaces by the `chunk.dummyChunk` implementation, which is just a no-op that implements `chunk.Data` interface) The PR also removes the protos for the ingester client (`pkg/ingester/client/ingester.proto`) which were only referenced in the removed `pkg/util/chunkcompat/compat.go` file.

Ed Welch	8ca1d1e0a4	Loki: simplify the FetchChunks method and optimize the experimental l2 cache a little more (#10160 ) What this PR does / why we need it: This started as a simple PR to optimize the new L2 chunks cache code such that we don't look up chunks in L1 that we know won't be there, however, the complexity of the FetchChunks method taking both a slice of requested Chunks as well as a slice of requested Keys made this really challenging. Looking at how we use this method, I saw no reason for there to be a requirement to pass both a list of chunks and keys, we only ever want the Chunks and everywhere we used this we were generating the list of keys external to this function from the list of chunks being passed in. The second change was to the implementation of how we process the cache results to look for found vs missing keys. The current implementation required the chunks to be sorted by external key so that it could iterate through them, I tested out a different version of this which uses a map instead of sorting and iterating. The map performance was slightly better in terms of reduced allocations, not enough to make a meaningful difference, but I think this code is easier to understand and reason about, and it removes any requirement for sorting of the passed in Chunks by External key.

Dylan Guedes	9159c1dac3	Loki: Improve spans usage (#8927 ) What this PR does / why we need it: - At different places, inherit the span/spanlogger from the given context instead of instantiating a new one from scratch, which fix spans being orphaned on a read/write operation. - At different places, turn spans into events. Events are lighter than spans and by having fewer spans in the trace, trace visualization will be cleaner without losing any details. - Adds new spans/events to places that might be a bottleneck for our writes/reads.	2 years ago
Danny Kopping	de84737368	Fix fetched chunk from store size in metric (#8971 ) What this PR does / why we need it: The `Size()` function on `chunk.Chunk` calls out to `func (ChunkRef) Size() int` in the proto, which doesn't actually include the size of the chunk data! We need to call `chunk.Data.Size()` for that.	2 years ago
Danny Kopping	ab7a970b94	Querier/Ruler: add histogram to track fetched chunk size distribution (#8682 ) What this PR does / why we need it: We are looking at making some changes to the chunk caching strategy, and we need this data to know what size chunks we're typically requesting. For example, if the overwhelming majority of chunks are small we may decide to cache only small chunks to decrease the number of requests to the object store; we could fit more chunks in cache this way, which may have a positive performance impact.	2 years ago
