This commit adds initial support for "soft" namespace deletion, where
the actual records & data remain, but are no longer queryable /
writeable.
Soft deletion is eventually consistent - users can expect to continue
writing to and reading from a bucket after issuing a soft delete call,
until the various components either restart, or have their caches
flushed.
The components treat soft-deleted namespaces differently:
* router: ignore soft deleted namespaces
* ingester: accept soft deleted namespaces
* compactor: accept soft deleted namespaces
* querier: ignore soft deleted namespaces
* various gRPC services: ignore soft deleted namespaces
This ensures that the ingester & compactor do not see rows "vanishing"
from the database, and continue to make forward progress.
Writes for the deleted namespace that are buffered in the ingester will
be persisted as normal, allowing us to support "un-delete" operations
where the system is restored to a the state at which the delete was
issued (rather than loosing the buffered data).
Follow-on work is required to ensure GC drops the orphaned parquet files
after the configured GC time, and optimisations such as not compacting
parquet from soft-deleted namespaces seems like a trivial win.
Fixes#6418.
Makes sure the querier, the router, and the ingest replica CLI all
accept and validate ingester addresses the same, except whether or not
at least one value is required.

- do not wait for a non-empty partition result (this doesn't make sense
if we are not running endlessly)
- modify entry point to allow the compactor to exit on its own (this is
normally not allowed for other server types)
This debugging tool was more useful in previous situations where it was
harder to get real data as input for the compactor.
It's currently causing a flaky test that isn't worth investigating.
Fixes#6190 by making it moot.

Ensure a HTTP error response contains a well-formed JSON structure
containing "code" and "message" fields (for backwards compatibility with
existing InfluxDB versions) and a correct "content-type" header.
Instead of looping and polling a fresh set of partitions and
constructing a stream from that, use an endless stream instead. This
helps w/ efficiency during roll-overs since we can already start to
process the next set of partitions while the last ones from the previous
round are still in-progress.
Closes#6750.

* feat: introduce scratchpad store for compactor
Use an intermediate in-memory store (can be a disk later if we want) to
stage all inputs and outputs of the compaction. The reasons are:
- **fewer IO ops:** DataFusion's streaming IO requires slightly more
IO requests (at least 2 per file) due to the way it is optimized to
read as little as possible. It first reads the metadata and then
decides which content to fetch. In the compaction case this is (esp.
w/o delete predicates) EVERYTHING. So in contrast to the querier,
there is no advantage of this approach. In contrary this easily adds
100ms latency to every single input file.
- **less traffic:** For divide&conquer partitions (i.e. when we need to
run multiple compaction steps to deal with them) it is kinda pointless
to upload an intermediate result just to download it again. The
scratchpad avoids that.
- **higher throughput:** We want to limit the number of concurrent
DataFusion jobs because we don't wanna blow up the whole process by
having too much in-flight arrow data at the same time. However while
we perform the actual computation, we were waiting for object store
IO. This was limiting our throughput substantially.
- **shadow mode:** De-coupling the stores in this way makes it easier to
implement #6645.
Note that we assume here that the input parquet files are WAY SMALLER
than the uncompressed Arrow data during compaction itself.
Closes#6650.
* fix: panic on shutdown
* refactor: remove shadow scratchpad (for now)
* refactor: make scratchpad safe to use
* test: Port a test that's not actually supported through the full gRPC API
* test: Port remaining field column/measurement fields tests
* test: Remove unsupported measurement predicate and clarify purposes of tests
Andrew confirmed that the only way to invoke a Measurement Fields
request is with a measurement/table name specified: <0249b5018e/generated_types/protos/influxdata/platform/storage/service.proto (L43)>
so testing with a `_measurement` predicate is not valid.
I thought this test would become redundant with some other tests, but
they're actually still different enough; I took this opportunity to
better highlight the differences in the test names.
* refactor: Move all measurement fields tests to their own file
* test: Remove field columns tests that are now covered in end-to-end measurement fields tests
Make a new trait, `InfluxRpcTest`, that types can implement to define
how to run a test on a specific Storage gRPC API. `InfluxRpcTest` takes
care of iterating through the two architectures, running the setups, and
creating the custom test step.
Implementers of the trait can define aspects of the tests that differ
per run, to make the parameters of the test clearer and highlight what
different tests are testing.
- use a single data structure for CLI args (not two)
- set mem limit default to 8GB (same as querier). We can always tune
this later, but we should not run with "unlimited" to begin with.
Sets up crate and wires up the main binary. No tests yet, no algorithm
framework, just the bare minimum.
Also I decided to not offer a gRPC server in `compactor2` at the moment
and hence did not implement any handle/delegate infrastructure. We add
this later if we need it. This also means compactor2 does NOT provide a
catalog service for now.

- name exec driver thread (instead of using the default that `thread::spawn`
gives us)
- provide number to every worker thread (both for the dedicatd executor
and for the main runtime)
- shorten thread names (current naming too long for most debug tools)
To support a case where someone calls WriteLineProtocol twice in
a row to simulate two write requests. The test should be able to
record this state before the two write requests and not twice.
Fixes#6506.
Also has the pleasant side effect of making this code simpler and less
hacky-- it now checks the number of Parquet files for the whole
namespace, which is useful in cases where the line protocol writes to
several tables.
This test was relying on a graceful shutdown of the ingester to drive a
WAL replay, restoring the buffered state at startup.
Now the shutdown causes the data to be persisted and not replayed, this
didn't work.

having to review numerous additional snapshots.
