From 30990a07eb1b51de5ea56037499e46d85ae57e04 Mon Sep 17 00:00:00 2001 From: Mingwei Zhang Date: Mon, 29 Jun 2026 21:42:16 -0700 Subject: [PATCH 1/5] perf: optimize database refresh with drop-and-rebuild indexes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three optimizations cut database refresh (bulk insert) time by 21–49% across all repositories: 1. Drop and rebuild indexes around bulk inserts — indexes are dropped before the insert loop and rebuilt in one efficient pass afterward, instead of being updated per-row. This is the primary win. 2. Remove redundant pfx2as indexes — idx_pfx2as_prefix_str (redundant with the BLOB range index) and idx_pfx2as_validation (3-value enum not worth indexing). lookup_exact rewritten to use prefix_start/ prefix_end/prefix_length BLOB range index. 3. Fix PRAGMA restore bug — store() methods no longer toggle synchronous/journal_mode PRAGMAs, preserving the connection's WAL/NORMAL defaults. Previously every refresh left the connection in DELETE/FULL mode, degrading query performance until restart. Also switches INSERT OR REPLACE to plain INSERT (tables are cleared before insert) and adds a db_refresh_bench example for measuring refresh performance with real production data. Performance (real data, release build): asinfo: 988ms → 330ms (67% faster) as2rel: 2230ms → 1765ms (21% faster) pfx2as: 8631ms → 4433ms (49% faster) rpki: 71ms → 66ms (already fast) All queries remain well under 1 second on 1.6M rows. --- CHANGELOG.md | 17 + Cargo.toml | 5 + docs/db-refresh-perf-investigation.md | 124 +++++ examples/db_refresh_bench.rs | 753 ++++++++++++++++++++++++++ src/database/monocle/as2rel.rs | 92 +++- src/database/monocle/asinfo.rs | 125 ++++- src/database/monocle/pfx2as.rs | 379 ++++++++++++- src/database/monocle/rpki.rs | 98 +++- 8 files changed, 1502 insertions(+), 91 deletions(-) create mode 100644 docs/db-refresh-perf-investigation.md create mode 100644 examples/db_refresh_bench.rs diff --git a/CHANGELOG.md b/CHANGELOG.md index d39f14e..2fee14c 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -4,6 +4,23 @@ All notable changes to this project will be documented in this file. ## Unreleased changes +### Performance Improvements + +* Optimized database refresh (bulk insert) performance by 21–49% across all + repositories.

Remove low-value pfx2as indexes + +Removed two indexes from `pfx2as`: +- `idx_pfx2as_prefix_str` — redundant; `lookup_exact` rewritten to use + the `prefix_start`/`prefix_end`/`prefix_length` BLOB range index that + already exists for `lookup_longest` and `lookup_covering`. +- `idx_pfx2as_validation` — indexes a 3-value enum (`valid`/`invalid`/ + `unknown`); `validation_stats()` and `get_by_validation()` use full + scans that complete in <350ms on 1.6M rows. + +This cuts index rebuild time by ~40% (from ~4.5s to ~3.0s). + +### 3. Fix PRAGMA restore bug + +All `store()` methods previously set `PRAGMA synchronous = OFF` and +`PRAGMA journal_mode = MEMORY` for the insert, then restored to +`PRAGMA synchronous = FULL` and `PRAGMA journal_mode = DELETE`. + +**The problem:** `DatabaseConn::configure()` sets connection defaults to +`journal_mode = WAL` and `synchronous = NORMAL`. After a refresh, the +connection was left in `DELETE / FULL` — slower and less concurrent than +the defaults.

The +connection stays at its configured `WAL / NORMAL` state throughout. + +### 4.
