Christian Haudum	d8cc1cea83	chore: Make dedicated iterator package (#13273 ) Iterators of various types are widely used throughout the Loki code base. With the recent code additions of the bloom filters, a new set of utility functions for iterators emerged in `github.com/grafana/loki/v3/pkg/storage/bloom/v1`. The package defines interfaces for various common types, but also provides implementations to create and compose new iterators that implement these interfaces. This new package uses Go Generics. - However, at the current state, there are multiple iterator interfaces and implementations, which adds cognitive overhead in understanding how they work and which ones should be used. The idea is to unify them into a single iterator lib for Loki. - As a first step towards a single iterator library for the Loki code base, this PR moves the utilities from the `pkg/storage/bloom/v1` package to the `pkg/iter/v2` package. - Second, it changes the existing `EntryIterator` and `SampleIterator` iterators to "inherit" `v2.CloseIterator` in order to expose the same function names. - And lastly, naming conventions of iterator interfaces and structs are unified. The basic iterator interface (defined in `pkg/iter/v2/interface.go`) looks like so: ```go // Usage: // // for it.Next() { // curr := it.At() // // do something // } // if it.Err() != nil { // // do something // } type Iterator[T any] interface { Next() bool Err() error At() T } ``` --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	11 months ago

Cyril Tovena	e81ca28c80	Fixes a bug in the block cache code. (#4302 ) * Fixes a bug in the block cache code. Because chunks can overlap and that can causes multiple processing of the same chunk within batches, we decided to cache the evaluation of it. However there was a bug here causing incorrect query result, specially for metric queries. The bug would occur when we would only partially consume a block (overlaping block between multiple batches) and then try to replay it. In which case it wouldn't actually replay it but keep consuming the underlaying iterator. This took us 2 days to figure out, thank Danny for helping along.

Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Fixes race conditions in the batch iterator. We should never advance an iterator in parallel. Unfortunately before the code was building iterators while advancing previous one, building iterator can advance iterator and thus creates a race condition. This changeset make sure we only fetch chunks in advance and build iterator and iterate over them in sequence. Also add support for labels in the cacheIterator which is required for logqlv2.
