* refactor: make `Cache` a trait
To insert more high-level metrics (e.g. cache misses/hits) it would be
helpful if we could easily instrument the layer right above the cache
driver (that combines the backend and the loader). To do that without
polluting the types too much, let's introduce a trait that describes the
driver interface and that we could later wrap with intrumentation.
This also pulls out the test into a generic setup, similar to how this
is done for the cache storage backends.
This does NOT include any functionality changes.

* refactor: rework querier concurrency limiting
With #4752 we introduced a concurrency limit into the querier. It works
by drawing permits from a central semaphore whenever we create a
`QuerierNamespace`. This however only limits concurrency during query
planning and not query execution, because the objects contained within
the plan (chunks and some metadata) neither reference the permit nor the
`QuerierNamespace`.
Now one approach to fix that would be to wire up the permit all the down
into all the query-related data structures. This however is very fiddly
and potentially will get lost at some point, because as soon as we
transform these data structures -- e.g. into streams -- the permit might
get lost again. This will be potentially query-dependent and very hard
to debug.
So instead we reverse the approach and track the permits at the upper
layer of the stack: the gRPC service entry points. There we also need to
be careful -- e.g. when we return streams to tonic -- but it's way
easier to review that then the deeply nested object hierarchy that is
involved with queries. Also the separation of concerns is a bit clearer,
because why would a "chunk" care about the "query concurrency" as a
whole.
* refactor: improve gRPC permit keeping and prepare tests
This is a rather quick fix for prod. On the mid-term we probably wanna
rethink our deployment strategy, e.g. by using "one query per pod" and
by deploying queryd w/ IOx into the same pod.
While logging all the helpful information to replicate failing
querier->ingester requests via CLI, I totally forgot to log the error
message itself.

With the ParquetStorage being solely responsible for managing

Removes two unused constructors for a ParquetChunk, and moves the bare

conventional constructor).

* refactor: querier<>ingester flight protocol adjustments
This makes a few adjustments to the querier<>ingester flight protocol.
Query Scope
===========
The querier will request data for ALL sequencer IDs for now. There is
no reason to have a request per sequencer ID. We can add a range/set
filter later if we want, but this is not required for now.
Partition-level
===============
The only time when the querier cares about sequencer IDs (i.e. sharding)
at all is when it selects which ingesters to ask for unpersisted data
(this is currently not implemented, it just asks all ingesters).
Afterwards the querier only cares about partitions (which are bound to
specific sequencers anyways) because this is the level where parquet
file persistence and compaction as well as deduplication happen. So we
make partitions a first-class citizen in the ingester response.
Metadata VS RecordBatches
=========================
The global app-metadata will list all partitions and their max
persisted parquet files and tombstones (theoretically tombstones are at
table-level, but the ingester could in the future break them down to the
partition-level). Then it receives a stream of record batches. Each
record batch is tagged (via key-value metadata in its schema) so it can
be assigned to a partition. At the moment the ingester returns 0 or 1
batches per unpersisted partition (0 in case we've filtered out all the
data via the predicate), but in the future it is free to return multiple
batches. This setup gives the ingester more freedom over memory
management and (potentially parallel) query processing, while at the
same time keeps the set of duplicated information minimal and allows
easy extensions (since the global metadata is a full-blown protobuf
message).
Querier
=======
At the moment the querier ignores all the metdata. Follow-up PRs will
change that.

"end-user -> querier" and "querier -> ingester" should use a single
Flight client implementation. The difference is just the request and

for the ticket format.

* refactor: cleanup tests a little

Abstract
========
We need to be careful w/ tombstone that fall exactly in sequence number range of a parquet file.
Current Bug
===========
Imagine the following order of events:
1. Router creates write at sequence number 1:
- `table,selector=1 payload=1 1`
- `table,selector=2 payload=2 2`
2. Ingester pulls write, waits a bit and persists it to parquet file 1:
- `table,selector=1 payload=1 1`
- `table,selector=2 payload=2 2`
4. Router creates write at sequence number 2:
- `table,selector=1 payload=3 3`
- `table,selector=2 payload=4 4`
5. Ingester pulls write
6. Router create delete at sequencer number 3: full time range, `selector=1`
7. Ingeser pulls delete and creates tombstone 1
8. Router creates write at sequence number 4:
- `table,selector=1 payload=5 5`
- `table,selector=2 payload=6 6`
9. Ingester pulls write
10. Ingester persists parquet file 2:
- `table,selector=2 payload=4 4`
- `table,selector=1 payload=5 5`
- `table,selector=2 payload=6 6`
When reading parquet file 2, the tombstone MUST NOT be applied. Otherwise `table,selector=1 payload=5 5` will be
deleted.
Notes
=====
Technically this issue also applies to files created by the compactor, however the compactor marks tombstones as
processed that fall into the sequence number range. It even does that in a single transaction:
fc4635a334/compactor/src/compact.rs (L821-L861)
Alternative
===========
An alternative solution would be if the ingester would mark tombstones that it materialized during persistence as
"processed" (tombstone 1 for parquet file 2 in the example above). However "processed" markers are currently a mere
optimization and don't affect correctness, which is nice for caching on the querier side as well as reasoning.

This allows us to remove the table name from the low-level chunk

catalog chunk) that manage the low-level chunk representations.
This is similar to #4167.

The parquet chunk is always wrapped into some higher-level data
structure (e.g. a catalog chunk, a partition, ...) that knows exactly
"where" the chunk is located. There is no need for the parquet chunk to
back-reference container-level attributes. In the contrary:
double-bookkeeping makes the code more complex and costs additional
memory.

The sort key is optional and currently only produced by `iox_tests`.
Writing it within the ingester/compactor is tracked by #3968. The sort
key is read by the querier (and this will be verified by the query tests
and is required to merge #4103).

* feat: `TombstoneRepo::list_by_table`
* feat: `ParquetFileRepo::list_by_table_not_to_delete`
* refactor: `querier` w/o `db`
Get the `querier` to work w/o relying on `db`. A few notes:
- Testing is kinda shallow, we really need to get `query_tests` working
w/ `querier` (see #3934).
- We still run a sync loop for namespaces, tables and schemas. This will
be a replaced by "update namespace incl. tables and schemas on demand".
Note however that we cannot fetch single tables and schemas on demand
at the moment, because DataFusion doesn't implement async schema
inspection (only `scan` / "give me all the chunks" is async). I think
that's OK for now and we can address this later.
- There is NO cache for parquet files and tombstones at the moment. For
correctness, they need to be fetched in a single transaction (or we
need a kinda tricky sequence number / logical clock tracking) and I am
not sure yet how this makes sense when we have the ingester data wired
up and predicates pushed down to the catalog (see next point). So
let's measure first and then decide on a caching strategy for this.
- Predicates are currently NOT pushed down to the catalog. I'll need to
figure out how to extract time range from generic DataFusion
expressions to make that work (it's easier for InfluxRPC queries, but
they are not tested at the moment, see first point).
Sorry that this commit is kinda huge. I initially planned to only
migrate the chunks away from `db` and leave the tables and schemas for a
follow-up PR, but the DataFusion trait structure (chunks are bound to
their tables) makes this kinda pointless.

- deal w/ missing tables w/o panics
- set proper timeouts to missing data
For #3974.
* test: extend table cache tests
- this is what DataFusion is doing as well; it's also fast enough
because the number of chunks in a query is not THAT massive (it's not
like we are doing row-level dyn dispatching)
- it simplifies abstracting over different databases
- it allows us to drop our enum-based dispatching that we have for
`DbChunk` and that we would also need for the querier (e.g. depending
on if a chunk is backed by a parquet file or ingester data)
- it likely speeds up compile times because the `query` is no longer
contains massive amounts of generic code
For #3934.

This will be useful for certain parts that are addressed internally via
ID but where the user-facing APIs use names.

- easiser to reason about the locking and consistency, esp. in

For OG we can determine the chunks w/o any IO, for NG however this might
require a few catalog queries.
This is likely not the last change of this sort, i.e. the whole schema
handling is currently sync as well.

Quite a few caches will request data from the catalog w/o knowing if it
exists (e.g. a table by name). We should have different TTLs for "exists"
and "unknown" w/o writing much boilerplate code.

In theory on a multi-threaded tokio executor, the following could have
happened:
| Thread 1 | Thread 2 |
| --------------------- | ----------------------------------- |
| | Running query begin |
| | ... |
| | `loader.await` finished |
| `Cache::set` begin | |
| state locked | |
| | try state lock, blocking |
| running query removed | |
| ... | |
| state unlocked | |
| `Cache::set` end | |
| | state locked |
| | panic because running query is gone |
Another issue that could happen is if we:
1. issue a get request, loader takes a while, this results in task1
2. side-load data into the running query (task1 still running)
3. the underlying cache backend drops the result very quickly (task1
still running)
4. we request the same data again, resulting in yet another query task
(task2), task1 is still running at this point
In this case the original not-yet-finalized query task (task1) would
remove the new query task (task2) from the active query set, even
though task2 is actually not done.
We fix this by the following measures:
- **task tagging:** tasks are tagged so if two tasks for the same key
are running, we can tell them apart
- **task->backend propagation:** let the query task only write to the
underlying backend if it is actually sure that it is running
- **prefer side-loaded results:** restructure the query task to strongly
prefer side-loaded data over whatever comes from the loader
- **async `Cache::set`:** Let `Cache::set` wait until a running query
task completes. This has NO correctness implications, it's probably
just nicer for resource management.

- This is not used by the query engine at all.
- The query engine should not care about ALL chunks but only about the
chunks it gets via `QueryDatabase::chunks` (which includes a table
name and a predicate).
- All other users of that API are NOT really query-related.
- This was not actually used by the query engine.
- The query engine doesn't have a concept of a "partition", it only
cares about chunks.
- Unbound access to all partitions in the database is quite expensive
(esp. on NG).

Before adding more and more features, here is a bit of a clean up and
prep work:
- Pull out caching into its own module and add proper tests for it.
- Start to build a test infrastructure so tests are shorter and easier
to read. This doesn't fully pay off just yet but gets more and more
important when we actually sync tables and chunks.
