-# AUX file v2
-
-## Summary
-
-This is a retrospective RFC describing a new storage strategy for AUX files.
-
-## Motivation
-
-The original aux file storage strategy stores everything in a single `AUX_FILES_KEY`.
-Every time the compute node streams a `neon-file` record to the pageserver, it will
-update the aux file hash map, and then write the serialized hash map into the key.
-This creates serious space bloat. There was a fix to log delta records (i.e., update
-a key in the hash map) to the aux file key. In this way, the pageserver only stores
-the deltas at each of the LSNs. However, this improved v1 storage strategy still
-requires us to store everything in an aux file cache in memory, because we cannot
-fetch a single key (or file) from the compound `AUX_FILES_KEY`.
-
-### Prior art
-
-For storing large amount of small files, we can use a key-value store where the key
-is the filename and the value is the file content.
-
-## Requirements
-
-- No space bloat, fixed space amplification.
-- No write bloat, fixed write amplification.
-
-## Impacted Components
-
-pageserver
-
-## Sparse Keyspace
-
-In pageserver, we had assumed the keyspaces are always contiguous. For example, if the keyspace 0x0000-0xFFFF
-exists in the pageserver, every single key in the key range would exist in the storage. Based on the prior
-assumption, there are code that traverses the keyspace by iterating every single key.
-
-```rust
-loop {
-    // do something
-    key = key.next();
-}
-```
-
-If a keyspace is very large, for example, containing `2^64` keys, this loop will take infinite time to run.
-Therefore, we introduce the concept of sparse keyspace in this RFC. For a sparse keyspace, not every key would
-exist in the key range. Developers should not attempt to iterate every single key in the keyspace. Instead,
-they should fetch all the layer files in the key range, and then do a merge of them.
-
-In aux file v2, we store aux files within the sparse keyspace of the prefix `AUX_KEY_PREFIX`.
-
-## AUX v2 Keyspace and Key Mapping
-
-Pageserver uses fixed-size keys. The key is 128b. In order to store files of arbitrary filenames into the
-keyspace, we assign a predetermined prefix based on the directory storing the aux file, and use the FNV hash
-of the filename for the rest bits of the key. The encoding scheme is defined in `encode_aux_file_key`.
-
-For example, `pg_logical/mappings/test1` will be encoded as:
-
-```
-62 0000 01 01 7F8B83D94F7081693471ABF91C
-^ aux prefix
-        ^ assigned prefix of pg_logical/
-           ^ assigned prefix of mappings/
-              ^ 13B FNV hash of test1
-   ^ not used due to key representation
-```
-
-The prefixes of the directories should be assigned every time we add a new type of aux file into the storage within `aux_file.rs`. For all directories without an assigned prefix, it will be put into the `0xFFFF` keyspace.
-
-Note that inside pageserver, there are two representations of the keys: the 18B full key representation
-and the 16B compact key representation. For the 18B representation, some fields have restricted ranges
-of values. Therefore, the aux keys only use the 16B compact portion of the full key.
-
-It is possible that two files get mapped to the same key due to hash collision. Therefore, the value of
-each of the aux key is an array that contains all filenames and file content that should be stored in
-this key.
-
-We use `Value::Image` to store the aux keys. Therefore, page reconstruction works in the same way as before,
-and we do not need addition code to support reconstructing the value. We simply get the latest image from
-the storage.
-
-## Inbound Logical Replication Key Mapping
-
-For inbound logical replication, Postgres needs the `replorigin_checkpoint` file to store the data.
-This file not directly stored in the pageserver using the aux v2 mechanism. It is constructed during
-generating the basebackup by scanning the `REPL_ORIGIN_KEY_PREFIX` keyspace.
-
-## Sparse Keyspace Read Path
-
-There are two places we need to read the aux files from the pageserver:
-
-* On the write path, when the compute node adds an aux file to the pageserver, we will retrieve the key from the storage, append the file to the hashed key, and write it back. The current `get` API already supports that.
-*  We use the vectored get API to retrieve all aux files during generating the basebackup. Because we need to scan a sparse keyspace, we slightly modified the vectored get path. The vectorized API will attempt to retrieve every single key within the requested key range, and therefore, we modified it in a way that keys within `NON_INHERITED_SPARSE_RANGE` will not trigger missing key error.
-
-## Compaction and Image Layer Generation
-
-With the add of sparse keyspaces, we also modified the compaction code to accommodate the fact that sparse keyspaces do not have every single key stored in the storage.
-
-* L0 compaction: we modified the hole computation code so that it can handle sparse keyspaces when computing holes.
-* Image layer creation: instead of calling `key.next()` and getting/reconstructing images for every single key, we use the vectored get API to scan all keys in the keyspace at a given LSN. Image layers are only created if there are too many delta layers between the latest LSN and the last image layer we generated for sparse keyspaces. The created image layer always cover the full aux key range for now, and could be optimized later.
-
-## Migration
-
-We decided not to make the new aux storage strategy (v1) compatible with the original one (v1). One feasible way of doing a seamless migration is to store new data in aux v2 while old data in aux v1, but this complicates file deletions. We want all users to start with a clean state with no aux files in the storage, and therefore, we need to do manual migrations for users using aux v1 by using the [migration script](https://github.com/neondatabase/aux_v2_migration).
-
-During the period of migration, we store the aux policy in the `index_part.json` file. When a tenant is attached
-with no policy set, the pageserver will scan the aux file keyspaces to identify the current aux policy being used (v1 or v2).
-
-If a timeline has aux v1 files stored, it will use aux file policy v1 unless we do a manual migration for them. Otherwise, the default aux file policy for new timelines is aux v2. Users enrolled in logical replication before we set aux v2 as default use aux v1 policy. Users who tried setting up inbound replication (which was not supported at that time) may also create some file entries in aux v1 store, even if they did not enroll in the logical replication testing program.
-
-The code for aux v2 migration is in https://github.com/neondatabase/aux_v2_migration. The toolkit scans all projects with logical replication enabled. For all these projects, it put the computes into maintenance mode (suspend all of then), call the migration API to switch the aux file policy on the pageserver (which drops all replication states), and restart all the computes.

-# Independent compute release
-
-Created at: 2024-08-30. Author: Alexey Kondratov (@ololobus)
-
-## Summary
-
-This document proposes an approach to fully independent compute release flow. It attempts to
-cover the following features:
-
-- Process is automated as much as possible to minimize human errors.
-- Compute<->storage protocol compatibility is ensured.
-- A transparent release history is available with an easy rollback strategy.
-- Although not in the scope of this document, there is a viable way to extend the proposed release
-  flow to achieve the canary and/or blue-green deployment strategies.
-
-## Motivation
-
-Previously, the compute release was tightly coupled to the storage release. This meant that once
-some storage nodes got restarted with a newer version, all new compute starts using these nodes
-automatically got a new version. Thus, two releases happen in parallel, which increases the blast
-radius and makes ownership fuzzy.
-
-Now, we practice a manual v0 independent compute release flow -- after getting a new compute release
-image and tag, we pin it region by region using Admin UI. It's better, but it still has its own flaws:
-
-1. It's a simple but fairly manual process, as you need to click through a few pages.
-2. It's prone to human errors, e.g., you could mistype or copy the wrong compute tag.
-3. We now require an additional approval in the Admin UI, which partially solves the 2.,
-   but also makes the whole process pretty annoying, as you constantly need to go back
-   and forth between two people.
-
-## Non-goals
-
-It's not the goal of this document to propose a design for some general-purpose release tool like Helm.
-The document considers how the current compute fleet is orchestrated at Neon. Even if we later
-decide to split the control plane further (e.g., introduce a separate compute controller), the proposed
-release process shouldn't change much, i.e., the releases table and API will reside in
-one of the parts.
-
-Achieving the canary and/or blue-green deploy strategies is out of the scope of this document. They
-were kept in mind, though, so it's expected that the proposed approach will lay down the foundation
-for implementing them in future iterations.
-
-## Impacted components
-
-Compute, control plane, CI, observability (some Grafana dashboards may require changes).
-
-## Prior art
-
-One of the very close examples is how Helm tracks [releases history](https://helm.sh/docs/helm/helm_history/).
-
-In the code:
-
-- [Release](https://github.com/helm/helm/blob/2b30cf4b61d587d3f7594102bb202b787b9918db/pkg/release/release.go#L20-L43)
-- [Release info](https://github.com/helm/helm/blob/2b30cf4b61d587d3f7594102bb202b787b9918db/pkg/release/info.go#L24-L40)
-- [Release status](https://github.com/helm/helm/blob/2b30cf4b61d587d3f7594102bb202b787b9918db/pkg/release/status.go#L18-L42)
-
-TL;DR it has several important attributes:
-
-- Revision -- unique release ID/primary key. It is not the same as the application version,
-  because the same version can be deployed several times, e.g., after a newer version rollback.
-- App version -- version of the application chart/code.
-- Config -- set of overrides to the default config of the application.
-- Status -- current status of the release in the history.
-- Timestamps -- tracks when a release was created and deployed.
-
-## Proposed implementation
-
-### Separate release branch
-
-We will use a separate release branch, `release-compute`, to have a clean history for releases and commits.
-In order to avoid confusion with storage releases, we will use a different prefix for compute [git release
-tags](https://github.com/neondatabase/neon/releases) -- `release-compute-XXXX`. We will use the same tag for
-Docker images as well. The `neondatabase/compute-node-v16:release-compute-XXXX` looks longer and a bit redundant,
-but it's better to have image and git tags in sync.
-
-Currently, control plane relies on the numeric compute and storage release versions to decide on compute->storage
-compatibility. Once we implement this proposal, we should drop this code as release numbers will be completely
-independent. The only constraint we want is that it must monotonically increase within the same release branch.
-
-### Compute config/settings manifest
-
-We will create a new sub-directory `compute` and file `compute/manifest.yaml` with a structure:
-
-```yaml
-pg_settings:
-  # Common settings for primaries and secondaries of all versions.

-        shared_preload_libraries: "neon,pg_stat_statements"
-      replica:
-        recovery_prefetch: "off"
-```
-
-**N.B.** Setting value should be a string with `on|off` for booleans and a number (as a string)
-without units for all numeric settings. That's how the control plane currently operates.
-
-The priority of settings will be (a higher number is a higher priority):
-
-1. Any static and hard-coded settings in the control plane
-2. `pg_settings->common`
-3. Per-version `common`
-4. Per-version `replica`
-5. Any per-user/project/endpoint overrides in the control plane
-6. Any dynamic setting calculated based on the compute size
-
-**N.B.** For simplicity, we do not do any custom logic for `shared_preload_libraries`, so it's completely
-overridden if specified on some level. Make sure that you include all necessary extensions in it when you
-do any overrides.
-
-**N.B.** There is a tricky question about what to do with custom compute image pinning we sometimes
-do for particular projects and customers. That's usually some ad-hoc work and images are based on
-the latest compute image, so it's relatively safe to assume that we could use settings from the latest compute
-release. If for some reason that's not true, and further overrides are needed, it's also possible to do
-on the project level together with pinning the image, so it's on-call/engineer/support responsibility to
-ensure that compute starts with the specified custom image. The only real risk is that compute image will get
-stale and settings from new releases will drift away, so eventually it will get something incompatible,
-but i) this is some operational issue, as we do not want stale images anyway, and ii) base settings
-receive something really new so rarely that the chance of this happening is very low. If we want to solve it completely,
-then together with pinning the image we could also pin the matching release revision in the control plane.
-
-The compute team will own the content of `compute/manifest.yaml`.
-
-### Control plane: releases table
-
-In order to store information about releases, the control plane will use a table `compute_releases` with the following
-schema:
-
-```sql
-CREATE TABLE compute_releases (
-  -- Unique release ID
-  -- N.B. Revision won't by synchronized across all regions, because all control planes are technically independent
-  -- services. We have the same situation with Helm releases as well because they could be deployed and rolled back
-  -- independently in different clusters.
-  revision BIGSERIAL PRIMARY KEY,
-  -- Numeric version of the compute image, e.g. 9057
-  version BIGINT NOT NULL,
-  -- Compute image tag, e.g. `release-9057`
-  tag TEXT NOT NULL,
-  -- Current release status. Currently, it will be a simple enum
-  -- * `deployed` -- release is deployed and used for new compute starts.
-  --                 Exactly one release can have this status at a time.
-  -- * `superseded` -- release has been replaced by a newer one.
-  -- But we can always extend it in the future when we need more statuses
-  -- for more complex deployment strategies.
-  status TEXT NOT NULL,
-  -- Any additional metadata for compute in the corresponding release
-  manifest JSONB NOT NULL,
-  -- Timestamp when release record was created in the control plane database
-  created_at TIMESTAMP NOT NULL DEFAULT now(),
-  -- Timestamp when release deployment was finished
-  deployed_at TIMESTAMP
-);
-```
-
-We keep track of the old releases not only for the sake of audit, but also because we usually have ~30% of
-old computes started using the image from one of the previous releases. Yet, when users want to reconfigure
-them without restarting, the control plane needs to know what settings are applicable to them, so we also need
-information about the previous releases that are readily available. There could be some other auxiliary info
-needed as well: supported extensions, compute flags, etc.
-
-**N.B.** Here, we can end up in an ambiguous situation when the same compute image is deployed twice, e.g.,
-it was deployed once, then rolled back, and then deployed again, potentially with a different manifest. Yet,
-we could've started some computes with the first deployment and some with the second. Thus, when we need to
-look up the manifest for the compute by its image tag, we will see two records in the table with the same tag,
-but different revision numbers. We can assume that this could happen only in case of rollbacks, so we
-can just take the latest revision for the given tag.
-
-### Control plane: management API
-
-The control plane will implement new API methods to manage releases:
-
-1. `POST /management/api/v2/compute_releases` to create a new release. With payload
-
-   ```json
-    {
-      "version": 9057,
-      "tag": "release-9057",
-      "manifest": {}
-    }
-   ```
-
-   and response
-
-   ```json
-    {
-      "revision": 53,
-      "version": 9057,
-      "tag": "release-9057",
-      "status": "deployed",
-      "manifest": {},
-      "created_at": "2024-08-15T15:52:01.0000Z",
-      "deployed_at": "2024-08-15T15:52:01.0000Z",
-    }
-   ```
-
-   Here, we can actually mix-in custom (remote) extensions metadata into the `manifest`, so that the control plane
-   will get information about all available extensions not bundled into compute image. The corresponding
-   workflow in `neondatabase/build-custom-extensions` should produce it as an artifact and make
-   it accessible to the workflow in the `neondatabase/infra`. See the complete release flow below. Doing that,
-   we put a constraint that new custom extension requires new compute release, which is good for the safety,
-   but is not exactly what we want operational-wise (we want to be able to deploy new extensions without new
-   images). Yet, it can be solved incrementally: v0 -- do not do anything with extensions at all;
-   v1 -- put them into the same manifest; v2 -- make them separate entities with their own lifecycle.
-
-   **N.B.** This method is intended to be used in CI workflows, and CI/network can be flaky. It's reasonable
-   to assume that we could retry the request several times, even though it's already succeeded. Although it's
-   not a big deal to create several identical releases one-by-one, it's better to avoid it, so the control plane
-   should check if the latest release is identical and just return `304 Not Modified` in this case.
-
-2. `POST /management/api/v2/compute_releases/rollback` to rollback to any previously deployed release. With payload
-   including the revision of the release to rollback to:
-
-   ```json
-   {
-      "revision": 52
-   }
-   ```
-
-   Rollback marks the current release as `superseded` and creates a new release with all the same data as the
-   requested revision, but with a new revision number.
-
-   This rollback API is not strictly needed, as we can just use `infra` repo workflow to deploy any
-   available tag. It's still nice to have for on-call and any urgent matters, for example, if we need
-   to rollback and GitHub is down. It's much easier to specify only the revision number vs. crafting
-   all the necessary data for the new release payload.
-
-### Compute->storage compatibility tests
-
-In order to safely release new compute versions independently from storage, we need to ensure that the currently
-deployed storage is compatible with the new compute version. Currently, we maintain backward compatibility
-in storage, but newer computes may require a newer storage version.
-
-Remote end-to-end (e2e) tests [already accept](https://github.com/neondatabase/cloud/blob/e3468d433e0d73d02b7d7e738d027f509b522408/.github/workflows/testing.yml#L43-L48)
-`storage_image_tag` and `compute_image_tag` as separate inputs. That means that we could reuse e2e tests to ensure
-compatibility between storage and compute:
-
-1. Pick the latest storage release tag and use it as `storage_image_tag`.
-2. Pick a new compute tag built in the current compute release PR and use it as `compute_image_tag`.
-   Here, we should use a temporary ECR image tag, because the final tag will be known only after the release PR is merged.
-3. Trigger e2e tests as usual.

-
-## Further work
-
-As briefly mentioned in other sections, eventually, we would like to use more complex deployment strategies.
-For example, we can pass a fraction of the total compute starts that should use the new release. Then we can
-mark the release as `partial` or `canary` and monitor its performance. If everything is fine, we can promote it
-to `deployed` status. If not, we can roll back to the previous one.
-
-## Alternatives
-
-In theory, we can try using Helm as-is:
-
-1. Write a compute Helm chart. That will actually have only some config map, which the control plane can access and read.
-   N.B. We could reuse the control plane chart as well, but then it's not a fully independent release again and even more fuzzy.
-2. The control plane will read it and start using the new compute version for new starts.
-
-Drawbacks:
-
-1. Helm releases work best if the workload is controlled by the Helm chart itself. Then you can have different
-   deployment strategies like rolling update or canary or blue/green deployments. At Neon, the compute starts are controlled
-   by control plane, so it makes it much more tricky.
-2. Releases visibility will suffer, i.e. instead of a nice table in the control plane and Admin UI, we would need to use
-   `helm` cli and/or K8s UIs like K8sLens.
-3. We do not restart all computes shortly after the new version release. This means that for some features and compatibility
-   purpose (see above) control plane may need some auxiliary info from the previous releases.
