From e3ba4db2a87630d1f153328faa49dc4629d38c38 Mon Sep 17 00:00:00 2001 From: zz_y Date: Wed, 8 Apr 2026 10:21:00 -0500 Subject: [PATCH 01/19] feat: replace Arroyo pipeline with hand-crafted precompute engine in e2e quickstart MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The e2e quickstart previously required Kafka, Arroyo, and asap-summary-ingest to run the streaming aggregation pipeline. This replaces that entire stack with the hand-crafted precompute engine running inside the query engine process, significantly simplifying the deployment. Changes: - Add `Precompute` variant to `StreamingEngine` enum - Make `--kafka-topic` and `--input-format` optional CLI args (only required when streaming-engine=arroyo) - Skip Kafka consumer when streaming-engine=precompute - Auto-enable precompute engine when streaming-engine=precompute - Remove Kafka, Arroyo, and asap-summary-ingest services from docker-compose - Point Prometheus remote_write to query engine's precompute ingest endpoint - Add healthcheck to query engine service for proper startup ordering Data flow before: Prometheus → Arroyo (via Kafka) → Kafka → Query Engine Data flow after: Prometheus → Query Engine (precompute engine, direct to store) Co-Authored-By: Claude Opus 4.6 (1M context) --- asap-query-engine/src/data_model/enums.rs | 3 +- asap-query-engine/src/main.rs | 96 ++++++++------ asap-quickstart/config/prometheus.yml | 4 +- asap-quickstart/docker-compose.yml | 148 ++-------------------- 4 files changed, 73 insertions(+), 178 deletions(-) diff --git a/asap-query-engine/src/data_model/enums.rs b/asap-query-engine/src/data_model/enums.rs index ad5a090..71bbf04 100644 --- a/asap-query-engine/src/data_model/enums.rs +++ b/asap-query-engine/src/data_model/enums.rs @@ -4,9 +4,10 @@ pub enum InputFormat { Byte, } -#[derive(clap::ValueEnum, Clone, Debug)] +#[derive(clap::ValueEnum, Clone, Debug, PartialEq)] pub enum StreamingEngine { Arroyo, + Precompute, } pub use asap_types::enums::{CleanupPolicy, QueryLanguage}; diff --git a/asap-query-engine/src/main.rs b/asap-query-engine/src/main.rs index 0be1d13..e58df65 100644 --- a/asap-query-engine/src/main.rs +++ b/asap-query-engine/src/main.rs @@ -20,13 +20,13 @@ use query_engine_rust::{ #[derive(Parser, Debug)] #[command(author, version, about, long_about = None)] struct Args { -

The router hashes by group key so all series sharing the same grouping labels land on the same worker and feed a single shared accumulator. For the quickstart (189K series, 7 pattern groups), this reduces accumulator count from 189K to 7, store writes/sec from 189K to 7, and eliminates query-time fan-in merge.

charset=UTF-8 Content-Transfer-Encoding: 8bit For keyed accumulators (MultipleSum, CMS, HydraKLL), the key passed to update_keyed must come from aggregated_labels — these are the labels that form the key dimension inside the sketch (e.g., which entry in a MultipleSumAccumulator's HashMap, which bucket in a CMS grid). Previously, extract_key_from_series used grouping_labels, which the planner sets to empty for keyed operators. This caused all samples to hash to the same internal bucket, collapsing distinct keys. Now matches the Arroyo SQL pattern: udf(concat_ws(';', aggregated_labels), value) -- key inside sketch GROUP BY concat_ws(';', grouping_labels) -- output group key Co-Authored-By: Claude Opus 4.6 (1M context) --- .../src/precompute_engine/worker.rs | 132 ++++++++++++------ 1 file changed, 92 insertions(+), 40 deletions(-) diff --git a/asap-query-engine/src/precompute_engine/worker.rs b/asap-query-engine/src/precompute_engine/worker.rs index 26ed153..904bde5 100644 --- a/asap-query-engine/src/precompute_engine/worker.rs +++ b/asap-query-engine/src/precompute_engine/worker.rs @@ -490,6 +490,12 @@ pub fn parse_labels_from_series_key(series_key: &str) -> HashMap<&str, &str> { } /// Route a single sample to `updater`, dispatching keyed vs. non-keyed based on config. +/// +/// For keyed accumulators (MultipleSum, CMS, HydraKLL), the key is extracted +/// from the series' **aggregated_labels** — these are the labels that become +/// the key dimension *inside* the sketch (e.g., which bucket in a CMS, which +/// entry in a MultipleSumAccumulator's HashMap).
