-# Per-Tenant GetPage@LSN Throttling
-
-Author: Christian Schwarz
-Date: Oct 24, 2023
-
-## Summary
-
-This RFC proposes per-tenant throttling of GetPage@LSN requests inside Pageserver
-and the interactions with its client, i.e., the neon_smgr component in Compute.
-
-The result of implementing & executing this RFC will be a fleet-wide upper limit for
-**"the highest GetPage/second that Pageserver can support for a single tenant/shard"**.
-
-## Background
-
-### GetPage@LSN Request Flow
-
-Pageserver exposes its `page_service.rs` as a libpq listener.
-The Computes' `neon_smgr` module connects to that libpq listener.
-Once a connection is established, the protocol allows Compute to request page images at a given LSN.
-We call these requests GetPage@LSN requests, or GetPage requests for short.
-Other request types can be sent, but these are low traffic compared to GetPage requests
-and are not the concern of this RFC.
-
-Pageserver associates one libpq connection with one tokio task.
-
-Per connection/task, the pq protocol is handled by the common `postgres_backend` crate.
-Its `run_message_loop` function invokes the `page_service` specific `impl<IO> postgres_backend::Handler<IO> for PageServerHandler`.
-Requests are processed in the order in which they arrive via the TCP-based pq protocol.
-So, there is no concurrent request processing within one connection/task.
-
-There is a degree of natural pipelining:
-Compute can "fill the pipe" by sending more than one GetPage request into the libpq TCP stream.
-And Pageserver can fill the pipe with responses in the other direction.
-Both directions are subject to the limit of tx/rx buffers, nodelay, TCP flow control, etc.
-
-### GetPage@LSN Access Pattern
-
-The Compute has its own hierarchy of caches, specifically `shared_buffers` and the `local file cache` (LFC).
-Compute only issues GetPage requests to Pageserver if it encounters a miss in these caches.
-
-If the working set stops fitting into Compute's caches, requests to Pageserver increase sharply -- the Compute starts *thrashing*.
-
-## Motivation
-
-In INC-69, a tenant issued 155k GetPage/second for a period of 10 minutes and 60k GetPage/second for a period of 3h,
-then dropping to ca 18k GetPage/second for a period of 9h.
-
-We noticed this because of an internal GetPage latency SLO burn rate alert, i.e.,
-the request latency profile during this period significantly exceeded what was acceptable according to the internal SLO.
-
-Sadly, we do not have the observability data to determine the impact of this tenant on other tenants on the same tenants.
-
-However, here are some illustrative data points for the 155k period:
-The tenant was responsible for >= 99% of the GetPage traffic and, frankly, the overall activity on this Pageserver instance.
-We were serving pages at 10 Gb/s (`155k x 8 kbyte (PAGE_SZ) per second is 1.12GiB/s = 9.4Gb/s.`)
-The CPU utilization of the instance was 75% user+system.
-Pageserver page cache served 1.75M accesses/second at a hit rate of ca 90%.
-The hit rate for materialized pages was ca. 40%.
-Curiously, IOPS to the Instance Store NVMe were very low, rarely exceeding 100.
-
-The fact that the IOPS were so low / the materialized page cache hit rate was so high suggests that **this tenant's compute's caches were thrashing**.
-The compute was of type `k8s-pod`; hence, auto-scaling could/would not have helped remediate the thrashing by provisioning more RAM.
-The consequence was that the **thrashing translated into excessive GetPage requests against Pageserver**.
-
-My claim is that it was **unhealthy to serve this workload at the pace we did**:
-* it is likely that other tenants were/would have experienced high latencies (again, we sadly don't have per-tenant latency data to confirm this)
-* more importantly, it was **unsustainable** to serve traffic at this pace for multiple reasons:
-    * **predictability of performance**: when the working set grows, the pageserver materialized page cache hit rate drops.
-      At some point, we're bound by the EC2 Instance Store NVMe drive's IOPS limit.
-      The result is an **uneven** performance profile from the Compute perspective.
-
-    * **economics**: Neon currently does not charge for IOPS, only capacity.
-      **We cannot afford to undercut the market in IOPS/$ this drastically; it leads to adverse selection and perverse incentives.**
-      For example, the 155k IOPS, which we served for 10min, would cost ca. 6.5k$/month when provisioned as an io2 EBS volume.
-      Even the 18k IOPS, which we served for 9h, would cost ca. 1.1k$/month when provisioned as an io2 EBS volume.
-      We charge 0$.
-      It could be economically advantageous to keep using a low-DRAM compute because Pageserver IOPS are fast enough and free.
-
-
-Note: It is helpful to think of Pageserver as a disk, because it's precisely where `neon_smgr` sits:
-vanilla Postgres gets its pages from disk, Neon Postgres gets them from Pageserver.
-So, regarding the above performance & economic arguments, it is fair to say that we currently provide an "as-fast-as-possible-IOPS" disk that we charge for only by capacity.
-
-## Solution: Throttling GetPage Requests
-
-**The consequence of the above analysis must be that Pageserver throttles GetPage@LSN requests**.
-That is, unless we want to start charging for provisioned GetPage@LSN/second.
-Throttling sets the correct incentive for a thrashing Compute to scale up its DRAM to the working set size.
-Neon Autoscaling will make this easy, [eventually](https://github.com/neondatabase/neon/pull/3913).
-
-## The Design Space
-
-What that remains is the question about *policy* and *mechanism*:
-
-**Policy** concerns itself with the question of what limit applies to a given connection|timeline|tenant.
-Candidates are:
-
-* hard limit, same limit value per connection|timeline|tenant
-    * Per-tenant will provide an upper bound for the impact of a tenant on a given Pageserver instance.
-      This is a major operational pain point / risk right now.
-* hard limit, configurable per connection|timeline|tenant
-    * This outsources policy to console/control plane, with obvious advantages for flexible structuring of what service we offer to customers.
-    * Note that this is not a mechanism to guarantee a minium provisioned rate, i.e., this is not a mechanism to guarantee a certain QoS for a tenant.
-* fair share among active connections|timelines|tenants per instance
-    * example: each connection|timeline|tenant gets a fair fraction of the machine's GetPage/second capacity
-    * NB: needs definition of "active", and knowledge of available GetPage/second capacity in advance
-* ...
-
-
-Regarding **mechanism**, it's clear that **backpressure** is the way to go.
-However, we must choose between
-* **implicit** backpressure through pq/TCP and
-* **explicit** rejection of requests + retries with exponential backoff
-
-Further, there is the question of how throttling GetPage@LSN will affect the **internal GetPage latency SLO**:
-where do we measure the SLI for Pageserver's internal getpage latency SLO? Before or after the throttling?
-
-And when we eventually move the measurement point into the Computes (to avoid coordinated omission),
-how do we avoid counting throttling-induced latency toward the internal getpage latency SLI/SLO?
-
-## Scope Of This RFC
-
-**This RFC proposes introducing a hard GetPage@LSN/second limit per tenant, with the same value applying to each tenant on a Pageserver**.
-
-This proposal is easy to implement and significantly de-risks operating large Pageservers,
-based on the assumption that extremely-high-GetPage-rate-episodes like the one from the "Motivation" section are uncorrelated between tenants.
-
-For example, suppose we pick a limit that allows up to 10 tenants to go at limit rate.
-Suppose our Pageserver can serve 100k GetPage/second total at a 100% page cache miss rate.
-If each tenant gets a hard limit of 10k GetPage/second, we can serve up to 10 tenants at limit speed without latency degradation.
-
-The mechanism for backpressure will be TCP-based implicit backpressure.
-The compute team isn't concerned about prefetch queue depth.
-Pageserver will implement it by delaying the reading of requests from the libpq connection(s).
-
-The rate limit will be implemented using a per-tenant token bucket.
-The bucket will be be shared among all connections to the tenant.
-The bucket implementation supports starvation-preventing `await`ing.
-The current candidate for the implementation is [`leaky_bucket`](https://docs.rs/leaky-bucket/).
-The getpage@lsn benchmark that's being added in https://github.com/neondatabase/neon/issues/5771
-can be used to evaluate the overhead of sharing the bucket among connections of a tenant.
-A possible technique to mitigate the impact of sharing the bucket would be to maintain a buffer of a few tokens per connection handler.
-
-Regarding metrics / the internal GetPage latency SLO:
-we will measure the GetPage latency SLO _after_ the throttler and introduce a new metric to measure the amount of throttling, quantified by:
- histogram that records the tenants' observations of queue depth before they start waiting (one such histogram per pageserver)
- histogram that records the tenants' observations of time spent waiting (one such histogram per pageserver)
-
-Further observability measures:
- an INFO log message at frequency 1/min if the tenant/timeline/connection was throttled in that last minute.
-  The message will identify the tenant/timeline/connection to allow correlation with compute logs/stats.
-
-Rollout will happen as follows:
- deploy 1: implementation + config: disabled by default, ability to enable it per tenant through tenant_conf
- experimentation in staging and later production to study impact & interaction with auto-scaling
- determination of a sensible global default value
-  - the value will be chosen as high as possible ...
-  - ... but low enough to work towards this RFC's goal that one tenant should not be able to dominate a pageserver instance.
- deploy 2: implementation fixes if any + config: enabled by default with the aforementioned global default
- reset of the experimental per-tenant overrides
- gain experience & lower the limit over time
-  - we stop lowering the limit as soon as this RFC's goal is achieved, i.e.,
-    once we decide that in practice the chosen value sufficiently de-risks operating large pageservers
-
-The per-tenant override will remain for emergencies and testing.
-But since Console doesn't preserve it during tenant migrations, it isn't durably configurable for the tenant.
-
-Toward the upper layers of the Neon stack, the resulting limit will be
-**"the highest GetPage/second that Pageserver can support for a single tenant"**.
-
-### Rationale
-
-We decided against error + retry because of worries about starvation.
-
-## Future Work
-
-Enable per-tenant emergency override of the limit via Console.
-Should be part of a more general framework to specify tenant config overrides.
-**NB:** this is **not** the right mechanism to _sell_ different max GetPage/second levels to users,
-or _auto-scale_ the GetPage/second levels. Such functionality will require a separate RFC that
-concerns itself with GetPage/second capacity planning.
-
-Compute-side metrics for GetPage latency.
-
-Back-channel to inform Compute/Autoscaling/ControlPlane that the project is being throttled.
-
-Compute-side neon_smgr improvements to avoid sending the same GetPage request multiple times if multiple backends experience a cache miss.
-
-Dealing with read-only endpoints: users use read-only endpoints to scale reads for a single tenant.
-Possibly there are also assumptions around read-only endpoints not affecting the primary read-write endpoint's performance.
-With per-tenant rate limiting, we will not meet that expectation.
-However, we can currently only scale per tenant.
-Soon, we will have sharding (#5505), which will apply the throttling on a per-shard basis.
-But, that's orthogonal to scaling reads: if many endpoints hit one shard, they share the same throttling limit.
-To solve this properly, I think we'll need replicas for tenants / shard.
-To performance-isolate a tenant's endpoints from each other, we'd then route them to different replicas.
