This commit changes the code base to use a new reference-counted
PartitionKey type wrapper, instead of passing a bare String around.
This allows the compiler to type check & verify usage of the partition
key, instead of passing a bare string around. By reference counting the
underlying string, we reduce memory usage for some use cases.
Unset the all env vars for the following CLI e2e tests:
* default_mode_is_run_all_in_one
* default_run_mode_is_all_in_one
This prevents them from executing against the "prod" catalog, running
migrations and inserting values to the prod database specified in the
prod DSN env (INFLUXDB_IOX_CATALOG_DSN).
Warn when downloading files to an in-memory object store.
The "remote partition pull" command downloads parquet files from an
object store via a router, and saves them locally. It's pretty unlikely
the user intends to download those files to memory of the CLI process
which then exits when the pull is complete, throwing away the downloaded
files, but this is the default.
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.

Co-authored-by: Andrew Lamb <andrew@nerdnetworks.org>
The default behavior of the ingester is to panic if the min unpersisted
sequence number in the catalog is unknown to the write buffer due to the
retention policies having evicted that sequence number.
Specifying `--skip-to-oldest-available` changes this behavior to skip to
the oldest sequence number the write buffer does have available and go
from there.
Fixes#4624.

Let's put all the caches into a single RAM pool, so we can at least

Connects to #4399.
Only file-based write buffer is supported. If `--data-dir` is specified,
store it there, otherwise store it in a temp directory to be ephemeral
Connects to #4399.
Manually flatten the arguments to set different defaults, not allow
setting the partition min/max, but still allow customization of the
other arguments.
Prior to this commit, adding any metric to the catalog (and only the
catalog) would cause the end_to_end_ng_cases::metrics::test_metrics test
to fail due to asserting an exact number of metrics observed.

than ==.

Attaching the "batch => partition" mapping via per-batch schema KV
metadata does NOT work because flight will transmit the schema once for
all batches (even though on the Rust side we have a schema ref attached
to every batch, probably for convenience). Instead we now use the same
global protobuf metadata that we also use for the "partition => max
sequence number" information. This somewhat limits our ability to create
record batches lazily on the ingester side (since the global metadata is
sent before any actual payload) but I think we should not modify the
usage of the flight protocol too much right now (e.g. by sending more
schema messages). If this becomes an issue, we can always find a more
complex solution in the future.
Add method to catalog to get parquet file by object store id.
Add gRPC service for object store to get a file from by its uuid.
Add the object store service to router2 with object store config.

* 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.

This commit adds an optional feature (disabled by default) to the IOx
server binary named "tokio_console". When enabled, it adds support for
the tokio-console to IOx:
https://github.com/tokio-rs/console
Enabling this feature drops the compile-time log filter to TRACE, and
enables the necessary dependencies to support the instrumentation needed
for the console to function.
Unfortunately, this feature uses tonic 0.7 (latest) while we use tonic
0.6, so we wind up with two tonic versions being compiled in when this
feature is enabled.
"end-user -> querier" and "querier -> ingester" should use a single
Flight client implementation. The difference is just the request and
response metadata.
This changes our default Flight client to use protobuf instead of JSON
for the ticket format.

Min/max values and distinct counts are already optional, so let's make
the null counts optional as well. This will be helpful for NG to deal w/
partial statistics (e.g. we only populate stats for the time column).
Note that the total count is still mandatory, but we normally have the
chunk/file-level row count at hand.

When you did a "cargo build --no-default-features" before this commit,
the influxdb_iox crate was compiled without the default features
(namely jemalloc stuff) but the influxdb_ioxd crate was compiled with
jemalloc (it was not possible to compile without jemalloc support).
This commit fixes propagation of the jemalloc flag
("jemalloc_replacing_malloc") into the influxdb_ioxd crate.

Removes openssl as a dependency, switching to rustls[1] as the TLS
implementation throughout.
It is important to note that this change brings with it a significant
behavioural difference - rustls does not currently support IP SANs in
certificates (instead only supporting fully-qualified names / DNS) and
this will manifest as a failure to connect to IP endpoints over TLS.
This might be a blocker that prevents us using rustls exclusively, but
there's noe asy way to know without trying it. Fortunately the rustls
project has received funding to work on IP SAN support[2].

Changes the configuration of the router request pipeline to move schema
validation before partitioning.
This reduces the concurrency of callsm into the schema validator when a
single write is split into one or more partitions, reducing contention
and cash thrashing. It also ensures we don't bother partitioning the
writes if the request will fail.
Wraps the postgres implementation of the catalog with a MetricDecorator.
This is slightly intrusive, with the metrics registry being pushed into
the PostgresCatalog type in order to decorate the impls returned when
calling the Catalog::repositories() and Catalog::start_transaction()
methods (rather than being a pure decorator) in order to use static
dispatch and let the compiler optimise away as much overhead as
possible.
