ClickHouse Support & Maintenance

Acosom provides ClickHouse support and managed services for enterprises running ClickHouse in production — on-premises, in the cloud, or hybrid.

Our engineers help you keep ClickHouse clusters healthy, performant, and up-to-date. From query optimization and schema management to cluster scaling and disaster recovery — we handle the operational complexity so your team can focus on analytics.

Whether you need ad-hoc ClickHouse support for an urgent issue, an ongoing maintenance contract, or full 24/7 managed operations — we have a plan that fits.

What’s Included

Our ClickHouse support covers every aspect of running ClickHouse reliably in production.

Query & Schema Optimization

Slow query analysis, index tuning, partition key design, and schema refactoring. We optimize your MergeTree table engines, sorting keys, and data skipping indices for maximum query performance.

MergeTree & ReplicatedMergeTree Management

Engine selection, replication topology management, and merge strategy tuning. We manage ReplicatedMergeTree configurations for high availability and ensure healthy merge operations across your cluster.

Materialized Views & Data Pipelines

Maintenance and troubleshooting of materialized views for real-time aggregations. Ensuring reliable data flow from Kafka, Flink, and other streaming pipelines feeding data into ClickHouse.

Cluster Scaling & Capacity Planning

Shard and replica management, resource allocation, and capacity forecasting. We scale your ClickHouse cluster to match growing data volumes and query workloads — without downtime.

Upgrades, Patching & Security

Version upgrades with rollback planning, security patches, and configuration hardening. We keep your ClickHouse deployment current and secure with minimal operational risk.

Backup, Recovery & Data TTL

Automated backup strategies, point-in-time recovery testing, and TTL policy management. We ensure your data lifecycle is controlled and your disaster recovery plan is tested and reliable.

Support Time Models

ClickHouse Support FAQ

What SLA response times do you offer?

We offer flexible SLA tiers depending on your chosen time model: Critical (4-hour response, 24/7), High (8-hour response, extended business hours), and Standard (next business day). SLAs are customizable based on your environment’s criticality. Every support engagement includes clearly defined response times, escalation paths, and reporting.

Can you support ClickHouse on-premises?

Yes. On-premises ClickHouse support is a core part of our offering. We work with bare-metal deployments, Kubernetes-based ClickHouse clusters, and hybrid setups. Data sovereignty and compliance requirements are fully supported.

Which pricing model is right for us?

It depends on your support volume. On Demand works well for teams with occasional issues. Flatrate is ideal if you want predictable costs with a guaranteed number of hours. All-Inclusive gives you unlimited coverage and full peace of mind — best for mission-critical ClickHouse platforms where you want zero risk of unexpected support costs.

What ClickHouse versions do you support?

We support all actively maintained ClickHouse versions, including both ClickHouse open-source and ClickHouse Cloud deployments. We also assist with version upgrades and migration from older releases.

How quickly can you onboard?

Typical onboarding takes 1-2 weeks depending on environment complexity. We handle monitoring integration, access setup, and initial health assessment during this period. Emergency onboarding is available for critical situations.
