Plausible Community Edition at 500M+ Views: ClickHouseCalc MergeTree Sizing Guide

In our deterministic ClickHouseCalc model, Plausible Analytics stores compact integer and dictionary columns inside `events_v2` and `sessions_v2` tables, allowing ZSTD(9) compression to retain 1,095 days of multi-domain traffic on modest NVMe footprints.

ClickHouseCalc MergeTree Production Checklist for plausible-analytics-high-traffic

  • Add `TTL event_date + INTERVAL 7 DAY` to ClickHouse `query_log`, `trace_log`, and `metric_log` in `config.d/system_logs.xml` so internal system logs do not outgrow your Plausible MergeTree tables.
  • Serve the 1.2 KB tracker script via a first-party subdomain edge (such as ChemiCloud or Hostinger HTTP/3 CDN) to reduce client-side adblocker script drops.
  • Align Elixir `DATABASE_POOL_SIZE=20` and `CLICKHOUSE_DATABASE_POOL_SIZE=15` with available vCPU threads.

ClickHouseCalc Engineering FAQ: plausible-analytics-high-traffic

Why does ClickHouseCalc warn Plausible CE operators to cap ClickHouse system.trace_log TTL on 100GB VPS disks?

Out of the box, ClickHouse retains `system.trace_log`, `system.metric_log`, and `system.part_log` indefinitely; adding a 7-day TTL and truncating stale system tables prevents surprise disk exhaustion on compact NVMe nodes.

How does ClickHouseCalc evaluate multi-domain query pruning for 50+ client sites on one Plausible MergeTree instance?

Plausible leads its MergeTree `ORDER BY` key with `domain_id` (`UInt64`), meaning single-tenant dashboard queries skip unrelated domain granules via `primary.idx` marks.
