Otherwise, as we have a lot of tenants in production, we cannot do a sum b/c Prometheus has limit on how many time series we can aggregate. This also helps reduce metrics scraping size. ## Summary of changes Some integration tests are likely not to pass as it will check the existence of some metrics. Waiting for CI complete and fix them. Metrics downgraded: page cache hit (where we are likely to have a page-server level page cache in the future instead of per-tenant), and reconstruct time (this would better be tenant-level, as we have one pg replayer for each tenant, but now we make it page-server level as we do not need that fine-grained data). --------- Signed-off-by: Alex Chi --- pageserver/src/metrics.rs | 41 +++++++++-------------------- pageserver/src/tenant/timeline.rs | 14 +++++----- test_runner/fixtures/metrics.py | 10 +++---- test_runner/regress/test_tenants.py | 2 +- 4 files changed, 25 insertions(+), 42 deletions(-) diff --git a/pageserver/src/metrics.rs b/pageserver/src/metrics.rs index cc444c479a..43d06db6d8 100644 --- a/pageserver/src/metrics.rs +++ b/pageserver/src/metrics.rs @@ -1,4 +1,3 @@ -use metrics::core::{AtomicU64, GenericCounter}; use metrics::{ register_counter_vec, register_histogram, register_histogram_vec, register_int_counter, register_int_counter_vec, register_int_gauge, register_int_gauge_vec, register_uint_gauge_vec, @@ -95,21 +94,19 @@ static READ_NUM_FS_LAYERS: Lazy = Lazy::new(|| { }); // Metrics collected on operations on the storage repository. -static RECONSTRUCT_TIME: Lazy = Lazy::new(|| { - register_histogram_vec!( +pub static RECONSTRUCT_TIME: Lazy = Lazy::new(|| { + register_histogram!( "pageserver_getpage_reconstruct_seconds", - "Time spent in reconstruct_value", - &["tenant_id", "timeline_id"], + "Time spent in reconstruct_value (reconstruct a page from deltas)", CRITICAL_OP_BUCKETS.into(), ) .expect("failed to define a metric") }); -static MATERIALIZED_PAGE_CACHE_HIT_DIRECT: Lazy = Lazy::new(|| { - register_int_counter_vec!( +pub static MATERIALIZED_PAGE_CACHE_HIT_DIRECT: Lazy = Lazy::new(|| { + register_int_counter!( "pageserver_materialized_cache_hits_direct_total", "Number of cache hits from materialized page cache without redo", - &["tenant_id", "timeline_id"] ) .expect("failed to define a metric") }); @@ -124,11 +121,10 @@ static GET_RECONSTRUCT_DATA_TIME: Lazy = Lazy::new(|| { .expect("failed to define a metric") }); -static MATERIALIZED_PAGE_CACHE_HIT: Lazy = Lazy::new(|| { - register_int_counter_vec!( +pub static MATERIALIZED_PAGE_CACHE_HIT: Lazy = Lazy::new(|| { + register_int_counter!( "pageserver_materialized_cache_hits_total", "Number of cache hits from materialized page cache", - &["tenant_id", "timeline_id"] ) .expect("failed to define a metric") }); @@ -752,10 +748,7 @@ impl StorageTimeMetrics { pub struct TimelineMetrics { tenant_id: String, timeline_id: String, - pub reconstruct_time_histo: Histogram, pub get_reconstruct_data_time_histo: Histogram, - pub materialized_page_cache_hit_counter: GenericCounter, - pub materialized_page_cache_hit_upon_request_counter: GenericCounter, pub flush_time_histo: StorageTimeMetrics, pub compact_time_histo: StorageTimeMetrics, pub create_images_time_histo: StorageTimeMetrics, @@ -783,15 +776,9 @@ impl TimelineMetrics { ) -> Self { let tenant_id = tenant_id.to_string(); let timeline_id = timeline_id.to_string(); - let reconstruct_time_histo = RECONSTRUCT_TIME - .get_metric_with_label_values(&[&tenant_id, &timeline_id]) - .unwrap(); let get_reconstruct_data_time_histo = GET_RECONSTRUCT_DATA_TIME .get_metric_with_label_values(&[&tenant_id, &timeline_id]) .unwrap(); - let materialized_page_cache_hit_counter = MATERIALIZED_PAGE_CACHE_HIT - .get_metric_with_label_values(&[&tenant_id, &timeline_id]) - .unwrap(); let flush_time_histo = StorageTimeMetrics::new(StorageTimeOperation::LayerFlush, &tenant_id, &timeline_id); let compact_time_histo = @@ -833,19 +820,18 @@ impl TimelineMetrics { let read_num_fs_layers = READ_NUM_FS_LAYERS .get_metric_with_label_values(&[&tenant_id, &timeline_id]) .unwrap(); - let materialized_page_cache_hit_upon_request_counter = MATERIALIZED_PAGE_CACHE_HIT_DIRECT - .get_metric_with_label_values(&[&tenant_id, &timeline_id]) - .unwrap(); let evictions_with_low_residence_duration = evictions_with_low_residence_duration_builder.build(&tenant_id, &timeline_id); + // TODO(chi): remove this once we remove Lazy for all metrics.

During the rollout we got a panic: "timeline that we were deleting was concurrently removed from 'timelines' map" that was caused by lock guard not being propagated to the background part of the deletion. Existing test didnt catch it because failpoint that was used for verification was placed earlier prior to background task spawning. 2. When looking at surrounding code one more bug was detected. We removed timeline from the map before deletion is finished, which breaks client retry logic, because it will indicate 404 before actual deletion is completed which can lead to client stopping its retry poll earlier. ## Summary of changes 1. Carry the lock guard over to background deletion. Ensure existing test case fails without applied patch (second deletion becomes stuck without it, which eventually leads to a test failure). 2. Move delete_all call earlier so timeline is removed from the map is the last thing done during deletion. Additionally I've added timeline_id to the `update_gc_info` span, because `debug_assert_current_span_has_tenant_and_timeline_id` in `download_remote_layer` was firing when `update_gc_info` lead to on-demand downloads via `find_lsn_for_timestamp` (caught by @problame). This is not directly related to the PR but fixes possible flakiness. Another smaller set of changes involves deletion wrapper used in python tests. Now there is a simpler wrapper that waits for deletions to complete `timeline_delete_wait_completed`. Most of the test_delete_timeline.py tests make negative tests, i.e., "does ps_http.timeline_delete() fail in this and that scenario". These can be left alone. Other places when we actually do the deletions, we need to use the helper that polls for completion.

In case of a crash restart we can remove such half-initialized timeline and following retry from control plane side should perform another attempt. So in case of a possible crash restart during initial loading we have following picture: ``` timelines | - ___uninit | - | - | ``` We call `std::fs::read_dir` to walk files in `timelines` directory one by one. If we see uninit file we proceed with deletion of both, timeline directory and uninit file. If we see timeline we check if uninit file exists and do the same cleanup. But in fact its possible to get both branches to be true at the same time. Result of readdir doesnt reflect following directory state modifications. So you can still get "valid" entry on the next iteration of the loop despite the fact that it was deleted in one of the previous iterations of the loop. To see that you can apply the following patch (it disables uninit mark cleanup on successful timeline creation): ```diff diff --git a/pageserver/src/tenant.rs b/pageserver/src/tenant.rs index 4beb2664..b3cdad8f 100644 --- a/pageserver/src/tenant.rs +++ b/pageserver/src/tenant.rs @@ -224,11 +224,6 @@ impl UninitializedTimeline<'_> { ) })?; } - uninit_mark.remove_uninit_mark().with_context(|| { - format!( - "Failed to remove uninit mark file for timeline {tenant_id}/{timeline_id}" - ) - })?; v.insert(Arc::clone(&new_timeline)); new_timeline.maybe_spawn_flush_loop(); ``` And perform the following steps: ```bash neon_local init neon_local start neon_local tenant create neon_local stop neon_local start ``` The error is: ```log INFO load{tenant_id=X}:blocking: Found an uninit mark file .neon/tenants/X/timelines/Y.___uninit, removing the timeline and its uninit mark 2023-06-09T18:43:41.664247Z ERROR load{tenant_id=X}: load failed, setting tenant state to Broken: failed to load metadata Caused by: 0: Failed to read metadata bytes from path .neon/tenants/X/timelines/Y/metadata 1: No such file or directory (os error 2) ``` So uninit mark got deleted together with timeline directory but we still got directory entry for it and tried to load it. The bug prevented tenant from being successfully loaded. ## Summary of changes Ideally I think we shouldnt place uninit marks in the same directory as timeline directories but move them to separate directory and gather them as an input to actual listing, but that would be sort of an on-disk format change, so just check whether entries are still valid before operating on them. --- libs/utils/src/http/error.rs | 3 +- pageserver/src/http/routes.rs | 14 +- pageserver/src/page_service.rs | 6 +- pageserver/src/tenant.rs | 337 ++++++++++-------- pageserver/src/tenant/mgr.rs | 6 +- .../src/tenant/remote_timeline_client.rs | 2 +- .../walreceiver/connection_manager.rs | 2 +- safekeeper/src/timeline.rs | 2 +- 8 files changed, 208 insertions(+), 164 deletions(-) diff --git a/libs/utils/src/http/error.rs b/libs/utils/src/http/error.rs index f9c06453df..527e486fd0 100644 --- a/libs/utils/src/http/error.rs +++ b/libs/utils/src/http/error.rs @@ -1,5 +1,6 @@ use hyper::{header, Body, Response, StatusCode}; use serde::{Deserialize, Serialize}; +use std::error::Error as StdError; use thiserror::Error; use tracing::error; @@ -15,7 +16,7 @@ pub enum ApiError { Unauthorized(String), #[error("NotFound: {0}")] - NotFound(anyhow::Error), + NotFound(Box), #[error("Conflict: {0}")] Conflict(String), diff --git a/pageserver/src/http/routes.rs b/pageserver/src/http/routes.rs index fc8da70cc0..5bec07b74a 100644 --- a/pageserver/src/http/routes.rs +++ b/pageserver/src/http/routes.rs @@ -142,7 +142,7 @@ impl From for ApiError { impl From for ApiError { fn from(tse: TenantStateError) -> ApiError { match tse { - TenantStateError::NotFound(tid) => ApiError::NotFound(anyhow!("tenant {}", tid)), + TenantStateError::NotFound(tid) => ApiError::NotFound(anyhow!("tenant {}", tid).into()), _ => ApiError::InternalServerError(anyhow::Error::new(tse)), } } @@ -151,7 +151,7 @@ impl From for ApiError { impl From for ApiError { fn from(tse: GetTenantError) -> ApiError { match tse { - GetTenantError::NotFound(tid) => ApiError::NotFound(anyhow!("tenant {}", tid)), + GetTenantError::NotFound(tid) => ApiError::NotFound(anyhow!("tenant {}", tid).into()), e @ GetTenantError::NotActive(_) => { // Why is this not `ApiError::NotFound`?

Logical size calculation currently does synchronous disk IO. This blocks the MGMT_REQUEST_RUNTIME's executor threads, starving other futures. While there's work on the way to move the synchronous disk IO into spawn_blocking, the quickfix here is to use the BACKGROUND_RUNTIME instead of MGMT_REQUEST_RUNTIME. Actually it's not just a quickfix. We simply shouldn't be blocking MGMT_REQUEST_RUNTIME executor threads on CPU or sync disk IO. That work isn't done yet, as many of the mgmt tasks still _do_ disk IO. But it's not as intensive as the logical size calculations that we're fixing here. While we're at it, fix disk-usage-based eviction in a similar way. It wasn't the culprit here, according to prod logs, but it can theoretically be a little CPU-intensive.

I suspect that is why they take so much time between the locks. * 80+% of wall-clock time spent writing layer files * Lock acquisition time is irrelevant (low double-digit microseconds at most) * The generation of the holes holds the read lock for a relatively long time and it's proportional to the amount of keys / IO required to iterate over them (max: 110ms in prod; staging (nightly benchmarks): multiple seconds). Find below screenshots from my ad-hoc spreadsheet + some graphs. image image image ## Changes In This PR This PR makes the following changes: * rearrange the `compact_level0_phase1` code such that we build the `all_keys_iter` and `all_values_iter` later than before * only grab the `Timeline::layers` lock once, and hold it until we've computed the holes * run compact_level0_phase1 in spawn_blocking, pre-grabbing the `Timeline::layers` lock in the async code and passing it in as an `OwnedRwLockReadGuard`. * the code inside spawn_blocking drops this guard after computing the holds * the `OwnedRwLockReadGuard` requires the `Timeline::layers` to be wrapped in an `Arc`. I think that's Ok, the locking for the RwLock is more heavy-weight than an additional pointer indirection. ## Alternatives Considered The naive alternative is to throw the entire function into `spawn_blocking`, and use `blocking_read` for `Timeline::layers` access. What I've done in this PR is better because, with this alternative, 1. while we `blocking_read()`, we'd waste one slot in the spawn_blocking pool 2. there's deadlock risk because the spawn_blocking pool is a finite resource ![image](https://github.com/neondatabase/neon/assets/956573/46c419f1-6695-467e-b315-9d1fc0949058) ## Metadata Fixes https://github.com/neondatabase/neon/issues/4492 --- pageserver/src/tenant/timeline.rs | 262 ++++++++++++++++-------------- 1 file changed, 139 insertions(+), 123 deletions(-) diff --git a/pageserver/src/tenant/timeline.rs b/pageserver/src/tenant/timeline.rs index 122331ac19..060000a01a 100644 --- a/pageserver/src/tenant/timeline.rs +++ b/pageserver/src/tenant/timeline.rs @@ -129,7 +129,7 @@ pub struct Timeline { pub pg_version: u32, - pub(crate) layers: tokio::sync::RwLock>, + pub(crate) layers: Arc>>, /// Set of key ranges which should be covered by image layers to /// allow GC to remove old layers.

The problem we're solving is that, before this patch, we'd execute `Layer::get_value_reconstruct_data` on the tokio executor threads. This function is IO- and/or CPU-intensive. The IO is using VirtualFile / std::fs; hence it's blocking. This results in unfairness towards other tokio tasks, especially under (disk) load. Some context can be found at https://github.com/neondatabase/neon/issues/4154 where I suspect (but can't prove) load spikes of logical size calculation to cause heavy eviction skew. Sadly we don't have tokio runtime/scheduler metrics to quantify the unfairness. But generally, we know blocking the executor threads on std::fs IO is bad. So, let's have this change and watch out for severe perf regressions in staging & during rollout. ## Changes * rename `Layer::get_value_reconstruct_data` to `Layer::get_value_reconstruct_data_blocking` * add a new blanket impl'd `Layer::get_value_reconstruct_data` `async_trait` method that runs `get_value_reconstruct_data_blocking` inside `spawn_blocking`. * The `spawn_blocking` requires `'static` lifetime of the captured variables; hence I had to change the data flow to _move_ the `ValueReconstructState` into and back out of get_value_reconstruct_data instead of passing a reference. It's a small struct, so I don't expect a big performance penalty. ## Performance Fundamentally, the code changes cause the following performance-relevant changes: * Latency & allocations: each `get_value_reconstruct_data` call now makes a short-lived allocation because `async_trait` is just sugar for boxed futures under the hood * Latency: `spawn_blocking` adds some latency because it needs to move the work to a thread pool * using `spawn_blocking` plus the existing synchronous code inside is probably more efficient better than switching all the synchronous code to tokio::fs because _each_ tokio::fs call does `spawn_blocking` under the hood. * Throughput: the `spawn_blocking` thread pool is much larger than the async executor thread pool. Hence, as long as the disks can keep up, which they should according to AWS specs, we will be able to deliver higher `get_value_reconstruct_data` throughput. * Disk IOPS utilization: we will see higher disk utilization if we get more throughput. Not a problem because the disks in prod are currently under-utilized, according to node_exporter metrics & the AWS specs. * CPU utilization: at higher throughput, CPU utilization will be higher. Slightly higher latency under regular load is acceptable given the throughput gains and expected better fairness during disk load peaks, such as logical size calculation peaks uncovered in #4154. ## Full Stack Of Preliminary PRs This PR builds on top of the following preliminary PRs 1. Clean-ups * https://github.com/neondatabase/neon/pull/4316 * https://github.com/neondatabase/neon/pull/4317 * https://github.com/neondatabase/neon/pull/4318 * https://github.com/neondatabase/neon/pull/4319 * https://github.com/neondatabase/neon/pull/4321 * Note: these were mostly to find an alternative to #4291, which I thought we'd need in my original plan where we would need to convert `Tenant::timelines` into an async locking primitive (#4333). In reviews, we walked away from that, but these cleanups were still quite useful. 2. https://github.com/neondatabase/neon/pull/4364 3. https://github.com/neondatabase/neon/pull/4472 4. https://github.com/neondatabase/neon/pull/4476 5. https://github.com/neondatabase/neon/pull/4477 6. https://github.com/neondatabase/neon/pull/4485 7. https://github.com/neondatabase/neon/pull/4441 --- pageserver/src/tenant/storage_layer.rs | 51 ++++++++++--- .../src/tenant/storage_layer/delta_layer.rs | 15 ++-- .../src/tenant/storage_layer/image_layer.rs | 15 ++-- .../tenant/storage_layer/inmemory_layer.rs | 15 ++-- .../src/tenant/storage_layer/remote_layer.rs | 13 ++-- pageserver/src/tenant/timeline.rs | 73 ++++++++++++------- 6 files changed, 118 insertions(+), 64 deletions(-) diff --git a/pageserver/src/tenant/storage_layer.rs b/pageserver/src/tenant/storage_layer.rs index 0af3d4ce39..06b90decd2 100644 --- a/pageserver/src/tenant/storage_layer.rs +++ b/pageserver/src/tenant/storage_layer.rs @@ -12,7 +12,7 @@ use crate::context::RequestContext; use crate::repository::{Key, Value}; use crate::task_mgr::TaskKind; use crate::walrecord::NeonWalRecord; -use anyhow::Result; +use anyhow::{Context, Result}; use bytes::Bytes; use enum_map::EnumMap; use enumset::EnumSet; @@ -343,7 +343,8 @@ impl LayerAccessStats { /// All layers should implement a minimal `std::fmt::Debug` without tenant or /// timeline names, because those are known in the context of which the layers /// are used in (timeline). -pub trait Layer: std::fmt::Debug + Send + Sync { +#[async_trait::async_trait] +pub trait Layer: std::fmt::Debug + Send + Sync + 'static { /// Range of keys that this layer covers fn get_key_range(&self) -> Range; @@ -373,13 +374,42 @@ pub trait Layer: std::fmt::Debug + Send + Sync { /// is available.
