Comparison

ClickHouse logging API without running ClickHouse

ClickHouse is a columnar analytics database, and ClickStack adds observability tools. Telemetry hosts event ingestion, SQL queries, dashboards, and alerts so you do not have to assemble or operate that stack.

Evaluation evidence

Try self-hosted ClickHouse alongside Telemetry

Choose one self-hosted ClickHouse workflow and test both systems with the same fixed dataset. Check which capabilities you still need before changing production monitoring.

  1. 1

    Inventory self-hosted ClickHouse

    ClickHouse tables and MergeTree schemas

  2. 2

    Map one workflow

    Managed event tables whose columns are inferred from stable JSON contracts.

  3. 3

    Dual-run the fixture

    Test type compatibility, timestamp units, nullability, and representative nested fields.

  4. 4

    Record the decision

    Do you need full control, OpenTelemetry correlation across logs/metrics/traces, or very large-scale analytics? ClickHouse or ClickStack is likely the better fit.

How Telemetry is different

  • Telemetry hosts an event API, inferred tables, SQL, dashboards, and alerts in one application.
  • ClickHouse is a columnar database. ClickStack adds an OpenTelemetry observability UI, and managed ClickStack runs on ClickHouse Cloud.
  • Telemetry handles event ingestion and querying in a hosted application. ClickHouse gives you more control over storage and supports a broader range of analytical workloads.

When Telemetry is a good fit

  • You want SQL-first event analytics.
  • You have backend events, jobs, API logs, or agent traces to query.
  • You would rather ship instrumentation than operate another data system.

Where each product is strongest

self-hosted ClickHouse

  • Columnar analytics with control over schemas, ingestion, query tuning, and deployment.
  • Managed ClickStack supports logs, metrics, traces, session replays, OpenTelemetry, dashboards, alerts, Lucene-style search, and SQL.
  • A stronger foundation for petabyte-scale observability, data warehousing, or custom analytics platforms.

Telemetry

  • An event API and query UI that does not require a ClickHouse deployment or OpenTelemetry pipeline.
  • Automatic table creation and a guided workflow for app, product, job, webhook, and agent events.
  • SQL queries and coding-agent templates for tasks such as tracking API errors and job failures.

Evaluation checklist

Test the decision with a real workflow

  1. 1Do you need full control, OpenTelemetry correlation across logs/metrics/traces, or very large-scale analytics? ClickHouse or ClickStack is likely the better fit.
  2. 2Do you have the engineering capacity to own schemas, ingestion, upgrades, backups, and security if you self-host?
  3. 3Prototype one real event stream and compare query capability, operational ownership, dashboard needs, and total cost at your expected scale.

Migration path

Plan the query and event migration before changing tools

List the queries, alerts, exports, and retention you use today. Define the event fields they need and translate one query. Run both systems with the same test data. Check null handling, timestamps, and aggregates before moving more queries.

Self-managed ingestion, storage, replication, and tuning

Telemetry mapping

A hosted ingestion-to-query path with fewer infrastructure controls.

Dual-run validation

Benchmark the real payload distribution, concurrency, retention, and query windows before migrating.

Try one workflow

Start with one backend workflow

Pick an API route, AI workflow, webhook, or job queue. Send structured events and query them before expanding coverage.
