[PERF] TSDB: Query head and ooo-head together

The current implementation of out-of-order querying runs two queriers which each iterate all series in the head, then runs a merge operation on the output.

This PR adds HeadAndOOOQuerier which iterates just once over series, then where necessary merges chunks from in-order and out-of-order lists.

In order to distinguish in-order from out-of-order chunk references I set bit 23 (i.e. 1<<23) on ooo references; this reduces the maximum number of chunks from 16 million to 8 million.

Note one side-effect of this change is that results may come in a different order - the merge operation done previously required a sort of all series. This only changes where Prometheus does not guarantee the order.

Fixes #11628

Bryan Boreham 512c67ec26 TSDB: Never go over maximum number of OOO chunks
In `mmapCurrentOOOHeadChunk`, check if the number is at the maximum and
drop the data with an error log. This is not expected to happen as the
maximum is over 8 million; that's 8 years of 1 sample every second.

* Move code making `Block` into a `Queryable` into test file.
* Make `getSeriesChunks` return a slice (renamed `appendSeriesChunks`).
* Rename `oooMergedChunks` to `mergedChunks`.
* Improve comment on `ChunkOrIterableWithCopy`.

Fix ToEncodedChunks minT for recoded chunks
2024-08-08 20:00:31 +02:00
György Krajcsovits 1ea3781699 Fix ToEncodedChunks minT for recoded chunks
Discovered while working on #14546 OOO native histograms.
Not triggered on main before #14546 as the code path is unused.

There was a bug where the min time of a chunk was adjusted even
if it was only recoded and not completely new.
